2015 Cummins Home Standby Generator IS IT DEAD ALREADY? Pt. 1/2

Cant make you buy a new one if the old one doesnt break down.

[@ryanhoaglin9907]

Planned obsolescence at its finest! Make it barely good enough so that it lasts a year after the warranty then croaks. Then make sure you don't sell the part to fix it. Short term thinking.

[@scdevon]

@@ryanhoaglin9907 It's why I only spend $400 bucks at a time on a Chinese knock-off inverter generator. I don't need 20kW to keep my food from spoiling in the fridge and to run a space heater. Hasn't failed me yet in 4 years of off and on RV and storm use.

Definitely consider blobbing those entire connections with some epoxy/resin so the copper doesn't work-harden from the vibrations; it seemed like the wires were floating a bit. I'm sure you already know that, but then I'd see absolutely nothing going wrong with those connections - lovely solder joints!

[@tomhoehler3284]

That bad connection to the slip rings is not poor assembly by workers; it is very bad engineering by the people who designed it. There are so many ways to make this connection properly, it's a shame they bypassed all the good designs and chose the worse possible design. But your repair is one of the best I have seen. Bravo, better than new!

[@HillbillySailor]

I love field repairs, especially if the field repair is better than the original design! You just came up with a fix you can apply to a customer's unit (who didn't think to but the extended warranty). Might be a little expensive, but it would beat replacing the whole gen set!

[@roygunter3244]

I will be the first to admit as soon as I saw the difference in colors on the windings I jumped to the immediate conclusion that the winding had let part of the smoke out of the unit. I have not ever tried to trouble shoot a generator but I did work on wound rotor motors that used remote resistor banks for speed control on 480 volt 3 phase. This was back in the 1980s and the cranes were 1969 series machines for the most part so it was all mostly relay controls with mechanical timers, motors up to 60 horse power. I recognize your trouble shoot technique, you have an analytical approach to trouble shooting. Not a shotgun approach where you just try everything in no particular order, which I have often observed. Good job.

Thanks! Working on a generator now that does not make power. Stator wires were black so I assumed the stator was bad even though it tested well and the ropes were not burned or broken. Just had another look and found the bridge rectifier was missing a diode. Will find out tomorrow if it lives again.

My brother-in-law is an electric motor rewind technician, he got me enough of the proper size wire (13 ga) to replace the damaged winding. I took the transformer to a local motor shop and they dipped and baked it for me. I used it for years after that.

[@daveberry5901]

@John Everlasting What gets me is, the first one of these videos was about one of the machines where because of Emissions laws the crank case vent has a short hose that dumped the crank case venting into the carburetor to such up and burn any oil vapors. Its a retarded idea. It kept freezing over. Whats really stupid is the idea of natural or propane gas. That thing will empty even a large household tank in a very short time, and if its a storm how to you get it refilled that fast. Just dumb.

[@daveberry5901]

@John Everlasting No No my good man. There was a great video this guy had talking about the propane/natural gas issue. . . The thing ran out much faster than he was told. And during a storm your not going to get a tanker truck out to get a refill.

I had bought a dishwasher and one day it wasn't starting the cycle. The service technician didn't even know what was wrong and said it was the logic board. But they didn't follow it up and they said they'd refund the money after waiting for almost 2 years and filing a complaint. I didn't touch it during the period to not void warranty. Later, I took a look inside and turned out it was a tiny reed switch for the flow sensor that wasn't making contact. By this time the tub had pitted with rust from the salt and moisture.

Great troubleshooting! Many years ago I had a british car with an alternator that only worked if you were accelerating. Finally found that one of the windings (3 phase) was cracked right were where it left the rotor - when accelerating the two ends touched and it would work, otherwise it was air gapped. Joe Lucas and all... But one technical note - when you moved from outdoors to your shop the right audio channel died. You might want to upload a fresh copy for those of us deaf in the left ear 😁

[@davidschwartz5127]

The first thing I noticed that when you were tapping the rear end bell off white dust was dropping out, I would not expect to see white dust maybe carbon dust if the unit had many hours on it. Wow, great diagnosis and find for an intermittent problem! A very primitive connection method for such an important connection looks Chianeezim. I like your repair, put but some epoxy on the pins and #14 wire to keep the wire tight to the rotor. Oh, one more thing, invest in a Milwaukee 3/8" drive battery-powered impact driver and retire the old-school ratchet but keep it because you still may need it once in a while. Thanks, I enjoyed it!

[@thefixerofbrokenstuff]

Might want to reinforce your 14 ga to rotor winding connection with some loom tape or string. The centrifugal force at 3600 rpm might cause a failure in the long run. I use a piece of plastic about 1/64 thick to wrap the rotor when pulling rotors and stators. Most of the units I work with dont have studs, they have bolts so you will get contact. I also tend to remove the rotor. No big deal. Just take a rotor bolt, cut off the head and about 1" off the bolt, saw in a screwdriver slot, and run a jacking bolt in the end of the rotor up against the modified rotor bolt. They usually pop right off. Nice to see that you and yours are still having fine days. Winter will soon be on us.

[@JBK63]

In the process of doing virtually the same thing on a Kohler 11RMY. Had a great deal of difficulty getting the end cap of the alternator off the rotor shaft, bearing on the Kohler is on the opposite side of the slip rings. Normally the endcap will pop off the bearing, and you were good to go, but in this case, I was ultimately able to get the bushing to slide off the shaft, but that took the slip rings with it. Currently in the process of replacing the bearing cleaning things up risotto ring the slip ring assembly to the windings and then put it all back together. I probably could have fixed the mouse wire damage, but I figured the smart thing to do would be pull the endcap off and inspect everything too bad it didn’t just come off easily. Like it’s supposed to, or at least with a few hammer taps.

Your observation at 19.26 regarding the different colour winding wire makes me wonder if they’ve been saving money by using aluminium wire , I’ve taken any amount of generators and motors apart for recycling, I quickly learnt to scratch the winding wire to ascertain whether it was copper or aluminium , if it was aluminium I didn’t bother wasting any more time to recover a metal that was a quarter the value of copper.

As others have stated, that is probably why that rotor is no longer made! One thing I would do is somehow support the 14 ga. wire and your solder connection. Maybe with a blob of epoxy or something that would stick to the nylon? Vibration and centrifugal force may break the connection. Just a thought.

I really enjoyed watching you also the fact that you improvised to find solutions I have many years experience and was truly impressed with your approach to getting the job done thanks for the video

I replaced a rotor on a 20K Kohler in the snow and rain. The rotor had slightly high resistance that was probably caused by the same the exact same issue. Fortunately the new rotor solved the problem. It was about a $900 part.

A jones is 100% right Cummins has taken the cheap route out. But look what it cost them the original buyer got a new unit. And Mike gets to give us a lesson in a great way by the way he explains very well. Mike the Bibs look great yeah.
