Lovers of all bikes

I know some people hate Harleys and some love them. Some love all bikes. This is aimed at those who love bikes including Harleys. I have had very little issues with my Harley. Love it equal to all my other bikes.

I have been trouble shooting my 02 Wideglide. It flashes trouble codes of 1 1 which is a high voltage above 15 volts for more than 5 seconds. I have read voltages at the battery while running at various times and could never read overe 14.4 volts. Puzzled I have lived with this error for about 2 years.

I picked up my research on this 1 1 issue and decided to pursue the warning. What I did was connect my Fluke 87 to the battery, put it in the record mode and went for an hour long ride varying the speeds I rode at. When I got home I discovered my low voltage was 12.05 and high of 17.48. Ok, now I have observed the high volt situation. I ordered and replace the voltage regulator. My fault codes have been reset and I have been out on the bike 5 times without fault codes. I think I corrected my problem.

Prior to replacing the regulator my question is can high voltage open the main circuit breaker? While out on a ride one day I was coasting to a stop light and realized the bike was not running. I coasted to the shoulder of the road and shut it off. Key on engine started and I rode home. No I did not think of looking to see if the headlight was out or not. I have not experienced this again. Strange. Circuit breakers to my knowledge were for over current situations.

Looking for Harley information on a BMW forum may not be the best course of action so if you have other connections, I suggest you follow them as well.

Depending on how high the voltage got, it could trip something even a circuit breaker depending on how close it was running to the trip current. Keep in mind that as the applied voltage increases, so does the current through a particular circuit or component. It is also possible that if your bikes computer can detect a high voltage situation, it can also detect an extremely high situation and take some preventive action like shutting off the ignition. Those are questions for the Harley techs. Circuit breakers however usually require manual intervention to reset or in the case of a heat sensor, time to cool and auto reset so if the bike stalled and immediately restarted, I think determining the direct cause would be difficult if all else appeared normal. Hopefully it was somehow associated with the bad regulator and you won't have any further issues with stalling.
