I’ve read over all of the comments and watched the video. Firstly, really enjoyed the video and the troubleshooting steps. It reminds me of a trip to my ex father in laws house to check out an issue with his Generac 36KW. Yes, it’s a big house on Houston. He had been getting his Gen serviced by a company that mainly dealt with Kohler, and had dropped anout 5k in repairs. First thing I found was that the tech had put the wrong size fuse in which was….interesting to say the least. Gen then started fine but I’d noticed that the gas install was poor to say the least. Flex was used in a way it should not have been. Gas line was coming out of the house, which was a clear indicator Gen had been installed at time house was built (Note: ex FIL had NOT been original owner). I located the gas meter on the other side of the house and was shocked to find that the meter had a standard regulator with 7 in WC. Meter was….80 feet from Gen. One thing we do when we bid the install of a Gen regardless of brand is recommend upgrading to a 2psi meter. We explain to the customer the fact that various appliances pull gas differently. We then illustrate how those add up, and then actually add it all up! Tankless heaters are great but boy do they burn gas! If the customer doesn’t want the upgraded meter they sign an acknowledgment that they are declining despite it being recommended. One other comment on the FiL--400 amp service 200amp ATS. Which was installed against all existing codes. Builder installed generator and did so to stay within budget. Screwed up the install completely by doing so. The gen will continue to have alarms depending on what gas is being used by the appliances indoor. So, by the builder cutting corners on the install, a nice pricey unit sits there and will never work correctly. You get what you pay for. Clearly the customer cares enough to get a competent tech out to inspect and repair. Get the install done correctly up front. Period. Don’t go bottom dollar or you will run into issues! Also to poster…you mentioned Briggs and Kohler as alternatives to Generwreck, but not Cummins….what gives ?

I would say the gas pressure dip is just a normal dip if line size is marginal, a resovour (small tank) in line near the gen will make it go away completely, could install when the flex hose is installed, and it should be installed! nice video thx very much and to DM all I can say is WA WA WA

a tighter plug gap can make a BIG difference when starting. Remember , a magneto puts out more power the faster it spins, so when cranking there isn't a lot of juice to make a spark. I have had many units that were a little slow starting , and making the plug gap tighter made all the difference in the world.

14:31 the engine is partly flooded, until it can get the engine rpm high enough drag more air into the mix and lean the mix out. Incoming fuel pressure for natural gas is max 7"H2O. Your meter showed 8"H2O.

The fuel regulator doesn't have issues until it gets over 13" w.c. this is the same regular used for both LP and natural. (LP is rated up to 13") The reason they worried about the pressure being too high was the solenoid might not open. The problem hasn't returned and this was recorded over two years ago. (This must have worked) There's a reason why I knew exactly what was going to happen, this is an ongoing problem with these older models. I've spent hours and hours on the phone with tech services to never come up with anything, this wasn't my first problem like this. There was an issue with these older ones and they did not address it, if they did I didn't hear about it. I hardly ever work on them anymore. The desire is dead

I got called out for a suspected warranty issue on a newer Evolution 2 unit with the same code. Plugs were gapped to 0.040" where they were supposed to be 0.020" and the exhaust valves had zero lash. It was recently serviced by the local electrical shop, but they are not factory certified to do warranty work I had to call the owner to let him know what I found. Not a warranty issue; just incomplete service work.

Replaced w/ a 40a 12v relay (it's only 12v switching) and it's worked perfectly since. Per the relay MFG, the relay didn't even have a 12v rating.

Great Job would love to see you break down the process for checking low oil and hi temp switches also. What about the hunting problem on the 20 and 22 KW Generacs. I am in the Northeast and have had them sucking in snow in storms and shutting down. No help at Generac but I have solved the problem but would like to see what you came up with. Thanks
@HVACRSurvival
@HVACRSurvival 5 жыл бұрын
For the oil test I bought a oil pressure gauge that you would use in an vehicle and use that to read the pressure. I forget the exact pressure without looking it up but if it was well over what it should be and it's tripping out I would figure the switch is bad. If I only want to verify the control respond correctly you can always pull the switch terminal off or short it depending on whether it's an open or closed switch. Far as the hunting, I haven't had it happened too much, usually it's either a servo or a gas pressure issue. Checkout HVAC hacker, he seems to do more generators than I do. I used to do a lot more prior to where I am now.

Air filter gets plugged with snow, then residual heat from engine melts the snow leaving you with either a wet air filter or a frozen air filter. Either way about 10 min on the dashboard on high defrost dries the filter back out. A few cedar bushes about 7 foot away from the intake act as a good natural snow wind break. Curious to hear what your solution was.

This might be the case of a "Manufacturing Fault" I know at some point when they have intermittent issues like this and the problem is hard to detect, it can possibly be a factory fault. So hopefully they are within their warranty, but if not the (Relay, Starter Motor & Control Board) may need to be replaced, in that order to resolve the intermittent issue.

You need to check the voltage output, if you don't have a meter I wouldn't advise you to run it anymore until it's verified correct, you may end up blowing something up in the house. At this point it's time for you to call somebody that knows your type of generator.

Trying to figure out similar issue past few months on newer model throwing an error code (VSCF Comms Loss). Starts as needed a few times, but every so often (caught it once to actually see) starts, runs for a second or two at low RPM's but never really ramps up to full RPM like on a normal start, then quickly shuts down. Let it sit a few hours, clear code, then starts right up, engages to full RPM, and runs beautifully. AVR and wiring harness replaced plus new controller tried because of VSCF code). Like with your controller replaced, seemed to fix it only to happen again. The low RPM's before shutting itself down now seems like could be fuel pressure? Machine calls for 10 minimum, 12 maximum. Had LP supplier themselves out to check on their end with water manometer. Showed 11.8 not running and 11 running under load. So all good there, it seems. Found one case on net where entire internal regulator replacement solved similar issue and another where plunger and spring replaced, but also stepper motor and solenoid so can't pinpoint it to one item. Wondering if this, and your situation, and very similar mysteries posted out there, might be internal regulator on machine itself having occasional issues like plunger or plunger spring occassionaly sticking like you kind of allude to talking about the bellows? Unless lucky enough to catch pressure issue with gauge that one random time it might happen when temp, humidity, statistics or whatever are just right, would be difficult to catch. Thoughts? Any callback yet with winter temps affecting things? Thanks for detailed video; very thorough.

No one has said anything about it not running yet. I've had a lot of problems with low RPM test mode. I'll look in the book and see if I can figure out what's going on with yours. I assume you're a technician? Have you tried calling Generac?

I am actually the owner of a 15kW Ecogen with Evolution controller still under warranty. Have had issue for 3 months (1062 VSCF Comms Loss most often, 1063 VSCF mismatch once recently and 1064? Speed something or another one time awhile ago). Have a very good Generac technician, like yourself, working through it by the book, and yes has communicated with Generac directly. I personally am getting sucked down the rabbit hole trying to get it figured out researching documents and the internet as I need it to work automatically as it is needed often, not babysitting it wondering if it'll throw a code and being at the ready to clear said code and then manually starting it - has happened in manual start mode as well though. Works fantastic when it starts immediately and runs, which is much of the time. I've scoured the internet only to find that there are other very similar situations out there and narrowing it down to the root cause can be very difficult, as your video shows. I'm personally leaning towards internal gas regulator now, but it's not my call and must go by the book like you say - still would appreciate your opinion if willing to share tbough. Thanks again for the video.

Current spec on the oil is 5w-20 GEO oil. Conveniently it's a proprietary Generac only blend. Allegedly good for all Generac application up to 150kw. Not shure how I feel about drinking that Kool-Aid. They used tons of different engines over the years. But for my valuable 2 cents you can always gap the plugs tighter than the book value just not wider. Personally I set all the plugs I deal with to 0.020" and have not had return trips for no start issues relating to plugs. I did find a set of plugs once that refused to start at 0.023" but when reset to 0.020" started up just fine. And yes the book says the correct answer was 0.030" for that engine.

When i first started some of the older Generac guys recommended 0.02 as well, I believe that, my feeling is they were paid to design this and if they can't figure out how they wanted the damn thing set that's their own flipping fault. I don't recommend these standby generators, They're a waste of money, they're not reliable but if you have to rely on it because you're physically unable to get a portable then this is what you're stuck with or you buy a different brand. Today's current ones are much better, this is a lot older unit. Also in the book they showed multiple different oils depending on where you lived at, for where I live at in Ohio that was the best choice for multiple different temperature ranges. And that's still the same today and they never have told me that they had to have just a particular oil that they make. And I was certified up to 250,000 Watts at one time.

Don't discard mount. You will need it to lift the engine. Those stepper motors get hung up at times test 12. I replaced many stepper motors on these generac carburetors get hung up on occasion. Worked on every test except when I OHM It failed test 12. the stepper motor had uneven resistance on both coils. The resistance should be the same. Quiet mode sucks sounds like it wants to stall the whole test. You should have run it and warmed it up. I had stepper motor on a Kohler a few weeks ago hunt only when it ran for a while and started hunting. when it was cool it ohmed good when hot it failed. Your start relay contact points might not always make contact test 56. To check gas pressure leave the plastic air deflector in place and take the top gas port off the regulator you can test from there, or use a bushing on the drip leg outside the genset. Your gas pressure drop on start was too much. That generator is starving for gas that could create an rpm sense lose. Is there a pool heater connected to the gas line...

I understand not working on these enough and feeling rusty at times. In 2011 I was sent to Wisconsin for gen University at Generac. It was a 2 week training course and you have the books so you at least took the 3 day course. Generac I think has one of the most serious train ing I ever been through. So 9 hours of class and shop work to get followed by 4+ hours of homework. After I went to this class which focused mostly on larger machines and doing nothing but generator start ups my employer always wanted know why troubleshooting problems would take so long. My first generac failure was the brushes during hurricane sandy. Not a fast repair. Now lots of the 2011/2012 gen sets are aging and the starting to break down. Many repairs takes awhile just to get to the part. Your test 18 could lead you to test 60 which puts you on the magnetos. It takes me minimum an 1-1/2 - hours just to get to the magnetos if I have to replace them.

Then after replacing the carburetor since it is one piece on the newer evolution controllers. To get it to run yet still some hunting and had almost 70-hertz output. Test 60 failed while testing the magnetos. A bad diode which is tested on wire 18. Replaced the magnetos and it ran perfectly after that. I like your videos not many with techs working on Generators.

Hi Rick, great video and definitely one of of the more informative ones out there on the Generac / Honeywell units. I have a question and hope you can answer, this past weekend my in laws 17KW Generac which is 8 years old had a failure to start on Saturday for its weekly exercise. Display screen said check battery and it was obvious terminals were corroded , a wire brush cleaned things up and she fired right up with same 2 year old battery . In reviewing the event log and looking at the past start and stop indications the system logged 50 such events in chronological order with the last exercise being 8/18/2018 yet I was out there checking the unit on 12/31/2018, I asked the retired next door neighbor if he had heard the unit crank up recently and he said yes every Saturday at 10 like clock work. Do you know if the event logger only records up to 50 such past events and is that normal? Thanks in advance and Happy new year.

I believe I have discovered an intermittent bug in the Guardian controller. If you have run the generator using a manual start, for any reason - cleared a fault code and want to test it, or you have been away for a couple weeks, etc.; when you want to end the test run AVOID USING THE STOP BUTTON. Instead, press the AUTO button. If there is no backup power demand at this time, the generator will shut itself off and be ready to start on the next start command, whether it be from the controller (i.e. a power outage has occurred) or with a manual start command. I have found that using the STOP button can result in the next start command failing with a "Loss of RPM Sense" code. This only crops up about once in twenty start cycles, after being shut down each time using the STOP button (plus Enter, unplugging the 7.5 Amp fuse and putting it back in, etc.). I did not write the firmware in the controller's micro processor, but it seems like going from running on Manual to pushing AUTO, lets the controller go through a shut down routine that leaves the RPM Sensor register in a positive/confirmed state, and while cranking the engine, the controller will be in a zero fault status. However, by shutting down the generator using the STOP button, intermittently the controller will see a Loss of RPM fault status, and interrupt the starting process. I could be wrong, but going from running on Manual to pressing the AUTO button, has eliminated starting problems on my Generac Guardian backup generator.

And the owner put the negative cable on upside down. Ugh!!!!!! I was gonna mention "quiet mode" but you just wrapped up the video with that hypothesis. I'd have to agree that quite mode is ridiculous. And now the Evolutions run 5 minute exercises and if the installer put it quiet mode the oil looks like coffee with creamer. Hell even at 3600 rpm 5 minutes wont get rid of the condensation and the oil still looks like that of the gen hasnt ran much under a load between oil changes. Frustrating we cant change the run time.

I agree it does dip down, it's just the recovery time of the regulator. I'm pretty sure every generator that has a regulator seems to have done that. That's also why they put an expansion tank there after the fuel solenoid sometimes to attempt to give it some reserved capacity. Good eyes.

exactly, 100% fuel starvation, it's dropping way too low on start up, causing severe lean out(bog and backfire), then it's over-speeding pretty bad trying to catch up. First the gas line is undersized, adding a "large chamber" to smooth the flow and supply some fuel while giving the regulator, meter and line flow to react and catch up. that red handle gas valve is big restriction, replace with full port ball valve. pipe may not be reamed, probably too much dope inside at joints which restricts volume. Second thing, the paint looks fairly fresh on all the gas equipment, I'm willing to bet they got paint up on the regulator vent screen and maybe into it, which causes slow reaction. I'd say they need both a licensed gas fitter and the gas company to check and upgrade. low pressure fuels with instant high demands are a pain to deal with. same starvation issues occur on "tankless" heaters, nuisance lockout, seemingly random flame outs..

@@throttlebottle5906 I've seen pressure drops happen over and over again, even when the gas line is sized properly . I would have preferred to see it respond on a water manometer or a magnehelic gage because of the slow response the digital sometimes has. In attempts to remedy the drop I've had everything from Gas Company's coming out and digging up the check valves and upgrading meters etc etc and a lot of times the result ends up being no difference. I did check the book and gas line is under-sized. It should have been 1 inch over to the unit. If you have been dealing with customers any amount of time now, you know the next thing your going to hear is "why is it just now acting up after this many years." Then you talk them into spending the money to correct what you know is the one of the problems, then they bitch about it and then usually nothing changes. Even though it's now been corrected to Industry standards, now you're the bad guy trying to rip them off . As it stands they haven't had any problems since I was there. As I said in a video, the exercise was set for quiet mode, which I think is the biggest BS thing they've came out with. It does not allow the generator to get as hot as it needs to be to boil out the moisture in the oil, and because of the way they shut it down to achieve this, the motor runs like crap and can easily dropout on multiple failures in colder climates. If these were fuel injected, almost all the problems would be resolved. Except for one issue, = the cost of the generator.

@HVACRSurvival
@HVACRSurvival 6 жыл бұрын
Well it's not really grease, it's anti seize. I've been told auto mechanics have done it for quite a awhile. If you think about it you're putting a metal spark plug inside of another metal device of the engine, whether it be the same type of metal or a dissimilar metal there's still a chance of that metal becoming gaulded or stuck if it's left in there for a long duration of time. Generally if a spark plug is getting changed on a routine basis it's not a big deal but usually they are forgotten until it's an afterthought, spark plugs and the anti seize, (for the amount that you're using) is cheap extra protection, just like a seatbelt. Do a internet search on the Ford Triton spark plug issue. See what happens when they don't change the spark plugs for a 100k plus thousand miles. I'm being proactive, giving my customer more than they paid for. It's a total reverse logic from what this industry or any industry does. Unfortunately very few people give two farts and a flush about the workmanship they do nowadays. Not saying I'm the only one that cares but when I do pay someone to do something for me, which is almost never, I generally never get good service to the level that I try to give others. It just doesn't seem right to me but I understand I'm a little more OCD than most people .

There's a reason why Generac is the largest home standby generator provider. For the most part their newest designs are a lot better. I had problems getting technical service for Briggs & Stratton. Kohler's really good stuff but once again you got to be a Kohler dealer and if you're not you won't get any help so you're going to be very limited on who can work on your equipment. Honestly the best bang for the buck is Generac. Just make sure you go with a good dealer and the best dealer may not be always the best price but there's a reason why they can charge more, because they have great service. But do your research first before you choose.
