[@johnstephens5227]

Amen doctor, I spent 43 years in the automotive after market parts business, in the last twenty years everyone wanted to know what codes meant I would have to explain that there may be more than one problem causing that code to appear. Keep up the good work.🤓

[@allentaylor9073]

Everything you said is 100% true. As the saying goes "well, it's not that simple"

[@greenmarine5]

As always great Info Doc. I've got an 08 FXDL that I'm pulling my hair out with, with different codes while the errored components work fine and read fine on the multimeter. I've had the bike apart checking all wires, connections, sensors and modules. What you said in the video is 100% spot on, " it's not that simple" I think half the issues is the previous owner put a stage 1 screaming eagle air intake on and Python pipes but never had the bike properly mapped with a fuel controller.

[@LowCountryHarleyDavidson]

Right on!….Hoping for future success…Doc

[@oldamerican8070]

Thank God for guys like you, if it's electrical I am more than happy to let my Harley tech handle it. That way I don't have to pull out the hair I have left.

[@wolfgangnapiletzki8480]

Yes doc, I fully agree. In my practice (Ducati bikes) we have had various problems with broken cables or simple corrosion at plugs or mechanical connections. Sometimes hard to find. One thing is for sure, a diagnosic, even with a code is not always possible. Regards from Austria.

[@LowCountryHarleyDavidson]

Thanks for watching and your important info....Doc

[@michaelhazen8658]

Nice one Doc. There is a lot to it. and depending on the generation of system, the methods of troubleshooting can get all sorts of wild and wonderful. I just spent a ridiculous amount of time chasing down a cam sensor code on my new to me 2000 electra glide. Falsely assuming that the "professional shop" had done the job right caused me to chase all sorts of dead ends. In my frustration I had forgotten the basics: stop. assume nothing. approach it methodically. build an order of operations. The root cause? when updating the engine to use hydraulic cam chain tensioners, the professionals had used the cam sprocket that came with the kit and installed it without ever reading the instructions in, or description of, the OEM kit; which clearly states that an original style sprocket must be used and is not included. Nor had they even stopped to wonder why the original sprocket was so radically different than the kit sprocket. That the bike ran at all in that state is a mystery I havent solved yet.

[@doylehenderson319]

Thanks once again Doc!!!!! Not long ago while we were riding in the mountains my wife's 2018 Tri Glide had a dash light come on, so we pulled over and luckily we had cell service and after a Google search was able to learn how to see/pull the code to make sure we could make it home... luck was with us and we took the bike in to our dealer and it had a bad O2 sensor. Smart bike.... ;-)

[@leudwigvonshwartsenhelm3624]

Just bought a 2024 street bob. I love the bike, however It has a voltage problem. It threw up three codes and left me stranded on the side of the road. I had to get towed home. And then the dealership came by and picked up the bike. I'm still waiting to hear back from them. The bike has less than 200 miles on it. Gotta say i'm not impressed. When I buy a brand new anything, I expect it to work......

[@LowCountryHarleyDavidson]

I apologize for your experience. And inconvenience. A possible reason you have not heard news is because this is not normal and the dealer is working with the Factory……Doc

[@jamesedward4283]

Yes I agree a process in deed! I have a 21 Harley 48 and threw a B1211- fuel level sender shorted high side The dealership already replaced the pump and are going to replace the harness but I told them it's probably the resistor based of the wiring diagram because the pump still works when fuel gets to low than light comes on

[@Ken-wu6hr]

I deal with that everyday. Being a Automotive Technician. They go to a part store & get the codes read. Bring a part. I say. Do you want me to install your part, or fix your problem

[@richconstantino8485]

Too much technology for our own good!!! I know "we must embrace technology". Ok, so where has that brought us to. Bring back the old days of carbs and cables. No need to rely on all theses computers and sensors and chips and other countries to make them. Just my 2 cents. Love the videos and look forward to them every week

[@LowCountryHarleyDavidson]

Thanks for watching and sharing. In my opinion, The riders (owners) of today have not been exposed to How a Motor, Carb, Trans works so we have this tech so they too can enjoy what we love....Doc

[@donaldcross7978]

Great answer , one thing I learned on new electronics, mine was Forklifts, but same type - is 1 wire might do 2 to 3 things , atleast on the Newer Hyster forklift , one wire my do horn , and the same wire my also do 4 way flashers . At first I was saying it was crazy , but the Voltage , and lack there of can change how a switch works , learned that in Shop class in Jr High. Using a Orthoscope seeing how Voltage works in Waves shows how it works. Confusing, but how they work . I left forklift industry about almost 10 years ago , they seemed to be ahead of Auto industry on changing DC Voltage to AC , where a 36 volt DC battery would last 8 hour shift , changing the system to work on AC and same battery would last over 3 shifts of usage. Wave's of power will change the World if used Properly !!!

[@CVO_GUY]

I was getting a constant red security light and intermittent check engine light while riding down the road. When the HD tech pulled up the codes there were multiple ones. Come to find out it was all caused by a defective brake light switch.

[@grumerguy]

96 harley davidson ultra classic Electra glide was doing something really weird. A engine light came on but went off just as quickly. Then I would get the engine light on start each time I rode but it would go off. It wasn't a solid code and I was never able to get the code. My fuel mileage went bad and sometimes I couldn't even get it out of the drive before it died. It would die at stop signs and red lights. I looked up the symptoms and it would come back as the magnetti marelli fuel injection system that is on the bike. One weekend recently, I went on a 200 mile run on the old girl. She ran okay for the first 170 miles but the last 30 miles, she would kick off the cruise control with every bump on the highway and she just wasn't running good. When I got her home, I looked her over and I shut her off. The very next time I was going to ride her, I noticed the ammeter showing 10 volts and would not go any higher. I replaced the alternator earlier this year and it was working fine as far as I could tell until I took that 200 mile run. This whole time I'm thinking I'm gonna have to replace the magnetti marelli fuel injection with a delphi or a carburetor along with replacing my alternator. I decided to take it to a shop and have the alternator replaced. The shop did a fantastic job and were really fast and affordable to boot! Lo and behold, the new alternator alleviated all of the problems I was having with the fuel system. To date, I have had no problem with how she is running. I replaced the alternator myself the first time and I must have gotten some of the parts wrong. The stator must not have been rated 45 amps or the rotor rotor itself may have been the problem. The rotor taken off the first time had all of the magnets grouped together on one side of the rotor and the stator was burnt. The voltage regulator was also bad the first time. This second time it went out on me, exactly the same thing was found. All the magnets on the rotor I replaced had grouped to one side. The high temperature glue had failed. The stator was burnt and the voltage regulator was out. The guy who did the repair this time said it was a 45 amp alternator and the rotor was a sealed rotor. My fuel mileage is back up to 45 mpg where it had slipped to 41 to 39 with the old alternator and that was right after I installed it! It is much better now. I am elated I don't have to replace the fuel injection system. Some people have replaced their fuel injection to carburetor but at 2000 dollars to redo it, I was not looking forward to the cost. I could have done the delphi for a lot less but still the hassle of replacing it was not appealing in the slightest. We are coming to the end of the riding season but I'm gonna ride as long as I can before I have to cover her up for the season. I love my evo. She's been mine for three years and this is the first time I've had any trouble with her. This bike has been to Daytona week before. Apparently the old boy that owned her had some issues with the alternator on that trip. I am hoping we've got that issue solved permanently. I plan on riding her until I can't ride any more.

[@babybugspaw7085]

Thank you Doc, I’m so furious right now, I bought new 23’ RG and ordered stage 1 and new bars for it, parts came in and dropped off bike, days later (late yesterday) went and picked it up & 40 miles later, west to take ride to dinner and 3 lights came on and codes are P1100c and C1032c, I have suspicions that the dealership cleared codes to get me to pick up the bike knowing the lights would come on after I left, can that be possible to ride the bike until Tuesday (dealerships closed) with those specific codes showing? Any light shed from you would be great.

[@LowCountryHarleyDavidson]

It is possible the codes were created when connection were separated during the handlebar exchange. As long as the bike is running well. You will be fine. They are Historic codes. The concern is when the light stays on while riding. Please do not assume the dealer and techs are out to do you harm. Mistakes can be made. We…I am human…..Doc

Great job Doc, I'm a licensed automotive, marine mechanic and of course play with bikes.. but I know my limits... even after 44 years wrenching.. I literally could of been rich just answering those questions or the client puts the phone near the noise.. absolutely hilarious.. I so have a question if you could answer.. I have a 05 fat boy CVO with 18,000 kilometers on it.. it drives me nuts why my machine seems to idle to high after warm up. It's always idling around 1000. Now that's what the tach reads.. haven't verified with timing gun.. but I really loved that classic lower Harley shuffle that the old carbs did, you lnow the classic of timing of Harleys.. I've verified no vacuum leaks, never touched timing or mods on this prestine factory screaming eagle set up.. Any suggestions or theories?? Thank you for your time.. Pete from Canada

[@LowCountryHarleyDavidson]

Fuel injection changed the way Harleys sound at idle. You would think with all the sensors and mapping they could recreate the awesome shovel idle. There are reasons for the 1000 rpm idle. It take a lot of juice to run fuel injection. If you notice all Harleys with FI when started go to 1350 to 1450 rpm. thats to help the rotor/stator to send as much voltage to the battery after the starter took so much. at Idle the charging system in 05 barely keeps the battery up above 12.8 with all the lights adn FI system running. The bike's oil pump supplies oil and returns oil as fast as it turns. So if the idle was set at 750 lopping the motor would be starving for oil. The best way to get the sound you want is to research cams. Some manufactures can play with cam timing that comes pretty close to sounding old school......Doc

[@petehalasz7547]

@@LowCountryHarleyDavidson thank you so much for your quick response Doc... I do agree with the very hard and struggling start.. it's a shame that after warm up and full batt it wouldn't drop.. what kind of cam could create a lumpy idle without bad performance.. especially off the line..

Doc your good and we all know it. Here is a question I can not find the answer to. I have what started off as a winter project. Which is know a major build. Have a 2003 soft tail heritage with a numbered paint job with only 7,000 mls. Attempting to change out the gauge and have found that the new gauges will only function on a 2004 and newer. Why is this. Dakota digital phoned me and informed me that they were out of stock and would take six month to get one made. What is the change from 2003 to 2004 and it is not the injection that should have nothing to do with the gauge. Right??

[@matt8863]

Unless folks are mechanically inclined, and have that picnic table of diagnostic goodies...It's really best off to the dealer for DTC issues.

[@CenobiteBeldar]

But there are dealerships who will say it's normal. So, no, they're not always the best for issues. A Honda dealership has techs who work like drunks. There's a cable on my Honda Shadow 750 that they forgot to run through the clip that keeps the wires together. I asked the service writer at the desk at the dealership if the tech could simply just put it back through the loop. He didn't write it down and the tech didn't do it. I've taken my bike there several times for service over anything (I don't have a garage nor access to a lift) and the techs fail EACH TIME to spot the flaw. If you have pride in your work, show it. If you like what you do, it should come out of those hands working on the machine. Everything is artwork and mechanics are really just morticians/surgeons. Repair it and make it look like it's supposed to. But mechanics don't want to do that. Makes no sense to me whatsoever.

Just turned to E but should have made it at least 10 more miles, but so tried jumping, no. Tried with a little fuel, no. Even being jumped by a charger/jump pack, half the time barely cranked and other half cranked strong but no.

Tune went right in no problem until I started the bike. engine light was on. Check the codes and had P0031, P0051 (CURRENT) P0134, P0154 (HISTORIC) deleted with tuner. Now Im a smart guy, I have another bike, a boat, I like to tinker. I found the code and what it was. 02 sensor. So I follow the videos advice and tried to delete the codes. By the way you cant delete the codes with the Tuner attached. So the Codes come up and I click and hold, delete comes up, I click and nothing happens. Then Part number starts to scroll pass. So I head to Harley dealer. Now I know it may run like crap and/or crappy fuel millage. Harley said you cant delete current codes. (on going maybe?). So, appointment made for June 7th $130 to delete codes and plus parts and labor for those parts. What really got me was he didn't know what the code was he never asked and really didn't seem like he cared if I was doing damage to it by driving it up there. You would think he would have checked the codes give advice and said Mr, smith your ok to drive it home and come back later. or you should not drive the bike with this code it could damage it.

Codes are numbered. The lower numbered codes need to be addressed first. Many times the larger numbers are a by product of the smaller number codes…Doc

What a bunch of bullshit , pump it two times pull the choke out kick it and go riding !

I had a 2014 Streetglide sold it and bought a 2009 Heritage with 12000 miles one owner that has just a ECM & Catalytic Converter for the engine. Only thing I miss is the abs braking system.

😵‍💫 The two week waiting period to actually get the bike into the shop. Then they where unable to replicate the issue…….🤦‍♂️

Another reason for checkups at dealerships are to update your software

Awesome Scott....Doc

Hear is my comment,what does "no rsp"mean

[@LowCountryHarleyDavidson]

No communication between ECM, BCM and Speedo....Doc

Doc... I hope you check the comments on KZbin. I have a 2014 Fatboy Lo and I want to buy the protective rubber cover that goes over the data port. I asked the parts counter at my local HD dealer and she blankly looked at me like I was from Mars. If you could please give me a part number, I'd be forever grateful. I wish shops would stop hiring staff that know nothing about bikes/parts.

[@LowCountryHarleyDavidson]

This was not an easy find. Your year bike's Part break down does not include this part....finally found it! labeled a Weather Plug Part # 6990...Your welcome....Doc

[@beri232]

@@LowCountryHarleyDavidson oh boy.... I hope this is the wrong part number because my dealership just ordered up a 3992 part number. At least I have 2 part numbers to aim for now I guess.Thanks Doc.

bUS Er code

[@LowCountryHarleyDavidson]

No such code. But every code with a “U” in front of the number has to do with the failure of the ECM or BCM able to communicate with all the systems on the bike….Doc

[@markjames495]

I thought You were going to tell us what the codes THEMSELVES meant. You just told us how the check engine light works. worthless to Me.

[@LowCountryHarleyDavidson]

I'm sorry to disappoint. Any knowledge is worth having...Doc

[@dejonsmall9886]

If the bikes were made better, there wouldn't be any need to have codes...
