I just did a diagnostic on my girls Heritage with a 103 engine. I found the stator was good. Before I removed the voltage regulator I checked it to see if it had a good ground to the bike and it did not. Her regulator is mounted on a stamped bracket bolted to the frame. I removed the regulator from the bracket and the bracket from the bike. Everything behind the regulator was caked with road crap and what looked like old engine oil...possibly from a messy oil filter change or 2. I cleaned everything with brake clean and cleaned the 2 plugs going in and out of the regulator, roughed up the back of the regulator and the bracket and frame mounts with emery cloth and put it all back together. The ground between the regulator and frame was now good. The charging system went from 12.6 volts running at the battery to 12.9 at idle and 13.8 reving the engine. Once the battery returns to full charge all should be fine.
I've done this twice on my own Fatboy, learned that running that primary wire back to the connection was easier by cutting the old one at the regulator & connecting the new one to it to 'fish' it back thru the frame to the actual connection.👍
sound like a great hack for running the wire with ease thanks
My 2010 fat boy lo started with the engine light coming on and after 60mph my speedometer light would go out! Pain in the arse!! I ended up taking it claiming it was the stator however it was in fact the voltage regulator that was going out. I had them replace both to be safe. Mind you my bike has 57k miles on it. I appreciate this video as a woman who rides as it helps me to know what it is getting done to my bike!
The only video i found showing how to remove the black plastic fender to get to the long wire from VR. Thanks for showing that.
Hey man, thanks. You described exactly what just happened to me this afternoon. Except I didn’t make it home. Got bike towed to home. Found your video. Followed your lead, (no pun intended) found it was the regulator and now I’m shopping for a new one. Bravo! You just saved me hundreds of $$$ !!! Just one thing. On your stator test, you could have informed us that you are testing each plug against the other all the way around the three way phase connector. That was the only thing I did not hear or see you do or talk about. I guessed that was what you did and I duplicated your meter readings. Thanks for the great video. 👍
Awesome news glad it helped, there is a link in the video to the regulator I used, also do me a favor and hit that subscribe if you haven’t yet.
Done. I’m a subscriber 👍
Thanks for the sub
satwatchers awesome it helps us out ty also tell you friends
Mine just did this 2 days ago, so now got to check it. Happened to remember you had a vlog about bike quit charging. Came in handy to review
Awesome glad it helped. If you haven't subscribed yet please do I you already have Thank You!!
Thanks for a perfect video! My
2000 FATBOY is getting the exact same fix tomorrow after work.
Also from the BADGER STATE.
Ive done the regulator on my 76 chopper and my 08 heritage but my dads 06 had me stumped. Thank you
I might have to do this same thing. after a few days of not riding or starting the bike, it won't start. Hopefully mine is this simple. I just have to get back to my tools so I can get my multimeter to test. Thanks for putting this info out there though.
You are welcome, please subscribe if you haven't yet it helps us out alot.
Very useful information. I ended up on the side of the road today. Called the bike dealer cause its under warrAnty but it turns out it was the regulator... nice to know it’s a simple fix it it happens again in the future.
Sorry you broke down but glad they fixed you up.
I’m confused on your 3 pin setup and how you connected your meter to it. Can you explain that?
It was years ago, but I put pins in the connector so I could test the the voltage, sorry maybe search some other videos on the topic and they explain it better than I did

Thanks for the reply. Ride safe!
This same thing happened to me but i was 400 miles from home up in McCall, Idaho engine lght the battery light came on made it to Boise then it wouldnt start. Bought a new battery it fired up and i started my ride home at dusk about 50 miles later my lights started dimming nad then the bike started backfiring then shut off. Anyway after checking everything come to find it was my Stator replaced and all is well now. Nice video.
Sorry the bike quit on you, but awesome news you were able to fix it. Thanks for watching and subscribing.
Thanks I had the exact thing happen to my 2000 ultra, I don’t see the link to the voltage regulator on Amazon
I had a bad battery, jumped my bike, hopped on and rode off. A few minutes later the radio quit, followed by the gauge pegged out past 16V. Kept riding to find a place to pull over and smoke came out from under the seat. Found the stator shorted, and the artery cooked, seems like the voltage regulator is bad also. Used a meter to test the diodes, reads “OL” across all the terminals, but this method is surefire. Great opportunity to check those grounds as well. I would also not recommend jump starting a bike with a running vehicle.
Wow I have jumped a bike with a car before, and never had an issue but this will make me think twice.
What was your fix for this? My bike did this this weekend on a trip. The only thing yours did that mine didn’t was mine didn’t smoke.
Thank you so much for this video! Saved me a lot of money…
Awesome glad it helped, be sure to subscribe.
Perfect video,
Thank you sir!
YUP ur stator is good, thumbs up. Just went through this on my 91 Sporty1200, that was weird, I really thought my stator was toasted as the connector between it and RR was so hot is was
smoking. But knowing how to test the stator was good as it would have been a lot of trouble to
get a trailor and get the bike to a dealer, and of course what the would cost.
hi nice video, I had the same with my heritage M8 114, the regulator is'nt in the best of ideal places especially if it's raining a lot of spray comes off the front wheel, when mine broke it over charged the battery at 17.2 volts and distroyed that as well ,Hmmm
Hmm never heard of that, but anything is possible for sure, Thanks for watching, and if you haven't please subscribe.
Good video. Thank you for taking the time.
The first test to get the ac volts reading. Was nt he connected to stator and not the voltage regulator? The stator makes ac . The reg makes dc .it converts it to dc .
Excellent video!
Thanks hopefully it helped you
It's happening to me right now in the middle of nowhere, Good to know though , what I was thinking too✌️
I have a 2011 Fatboy low with only 16 K miles on it. I’m trying to buy that voltage regulator that you shared in your video. I don’t know how to check the link with Amazon and you can you share that with me. 😊😊
Thanks Sonny
You are welcome hope it helped
Thanks for the information
Well done thank you
Our pleasure!
Good video. Very useful
Excelent video Mate
Thanks !
than you i learned alit from you today
Glad it helped
Check all 3 coming out of the primary cover, to check before the regulator, check at the battery to check after the regulator.
Great video, very well done, thank you!
Thank You I hope it helped.
Thank you badger. This video showed me everything I needed to know. You're awesome!
just what I needed to know, thanks
@Ron Richter awesome glad it helped, if you haven't already please hit that subscribe button that is what helps us out.
Which wires are you testing?
couldnt see exactly where your test points are on the regulator. where are you hooking the ground up to test the three wires?
The ground is one of the wires.
Where did you get those 3 pins?
Mac tools is where I got mine probably 25 years ago these look about the same and less expensive. amzn.to/3cMigMW
Top video tiger 🐅
Thanks
Great video. However, I never saw which wire behind the fender is which and how to get to it. Oh well. Another day, another video.
Justjack613 just follow the wire from the regulator to where it is attached, it help on with a small nut
thanks!
You are welcome hope it helped
I’m having this exact same problem
I hope you get it fixed
Very useful .
Thanks

Thanks
Thanks for watching hope it helped
Thanks. 👌🏾👌🏾
Put a new battery on. Same lights came on. My next move is my voltage regulator then stater

before what is the stator
i got an iron 883 those 3 wires i think run to the stator on my bike,my regulator has gone again and i only got it replaced 1337 miles ago
Jesus loves you !
Um ok does he fix Harleys also.
