Check Engine Light

By Dennis Santopietro & filed under Harley Tips.

Q: I have an 07 Ultra Classic with just over seven thousand miles….not a typo…7K…the original owner never road it. I put about 150 miles on it and then pulled the fairing off to replace the stock mirrors with fairing mounted type …..and now the “check engine light” and charging light both light up about a minute after starting the bike. The bike had the stock battery from 2007 in it which I replaced with a new one. Problem still exists. Looked at the battery and realized I had forgotten to tighten the small bolts on the battery posts. After tighting them, the lights are still coming on. Switched out battery with another new battery…no help. I didn’t pull the maxi fuse when I removed the outer fairing like the instructions say to do. All the fuses are good….I’m thinking that the stator is bad but with so few miles, makes me wonder if that’s a good assessment. I DID NOT drill through any wiring installing the mirrors. Any ideas….? Thanks

A: Would be disappointing to have a charging system problem with so few miles. Regardless, that is where we would suggest you start. Test your charging system. Also, check your speedo head for stored diagnostic trouble codes.

    Try reading your codes and write them don if trouble.
    Hold your trip odometer button and turn on. Let go of button and you will enter. Look at trip odometer. Push 1 time and the p will flash. Push and hold to go into p. A code will show up. Write it down. Then push and hold to clear it. More than 1 code maybe there. Clear the same way. When done turn off ignswitch and give it a try.

    I have a 2014 street glide and my check engine light stays on. The diagnostic trouble code indicates P1655 ACR solenoid low/open. What is that and is this an easy fix?

    I’m having a similar issue with my 2015 Road King, check engine light comes on, I get P1510, P2127 & P2138 codes which seem to indicate there’s an issue with the throttle sensors? Stealership wants $125.00 just to diagnose, plus any other additives…has anyone had a similar issue?

    I have a 2014 Ultra Limited. The check engine and temp lights come on after a few miles. I checked the codes and got codes P1019 and U0184. I also checked the fans come one when I test them but when needed. I changed the temp sensors in the head and radiator in the left lower fairing. The U0184 code went away but the light still comes on and I still get code P1019.

    Why would a check engine light come on and stay on with my softail in off position? Light stays on all time

    where do I find what these codes are. I am sorry I bought this Twin cam it is designed so you can’t do your own work. I love my 72 FLH it is just a big lawn mower and easy to work on.
