have 2002 heritage softtail that has been shop and thousands of dollars spent hope someone can help. bike is cutting out power just shuts off while riding. have had dealer replace ignition module, voltage regulator, battery, starter, tilt switch, oil sending unit, all electrical parts have been replace, ignition coil, low oil pressure switch u name it it has been replace. has become dangerous to ride hope u can give me some answers. thanks

 

Yeah, I bet that's dangerous to ride. Sounds like you've tried all the usual suspects. Hate to say it, if you can't find the short, you might just need to put a new electrical harness on it. Not cheap but that might be the only remaining answer. Sorry to hear about your troubles.

 

1st try replacing your circuit breaker with stock one then if that dont work then try a 50amp circuit breaker.

when my charging system took a dump and i replaced it with a Compu-Fire 40 AMP 3 Phase charging systems i took it for a test ride and as i was riding it would go out just turn off well heres what i did i swapped out my stock circuit breaker with a 50amp circuit breaker from harley but you probably can get it at any auto parts store and if you dont know where your circuit breaker is located at its behind your splash guard between tire and frame.

remember my problem was i was tripping my circuit breaker with my new 40amp charging system and the old circuit breaker was 32 or 38amps max yours might be different so i am not responsible for what ever happens to your bike.

 

is the bike fuel inj,i remember in sturgis in 05 there was alot of HD's being towed out for no start and shut off because of a wire in the harness under the tank was too short and shutting the FP off,u never said if it just shuts off or starts to break up and stall,does it immediatly restart or do u have to crank the hell out of it

 

no it is not fuel injected but thanks for your help

 

thnaks for advice the bike shuts down and when i turn key on and off as i am coasting the bike will refire then shut down acouple minutes later so frustrated. bought bike in february and has been in shop since lol any ideas would be appreciated

 

how about the ign switch,kill switch,i work on waverunners,bad kill switch seen alot go bad , only thing left to do is an ohms test on all ign wires associated with the + and - from switch,same to ign mod and coils,something is breaking down,bad connection ie corrosion,it will overheat a wire and break a connection even intermittently,did u pay for all the parts ?

 

yes i bought all parts and the worst part is no electrical parts are warranteed.. brought it to dealership and said they were going to change all the parts that were replaced from another mechanic and then they were going to change the crank at the sum of 4000 or more but could not guarentee anything guess what the bike went back on trailer is now down at another guy two hours away. This mechanic comes highly recommended we will see. hopefully i will be able to enjoy some riding thanks for all the help

 

I had a similar issue a few years back and it wound up being dirty contacts in the Ignition Switch...I'd lose 12V to the ignition coil and when I cycled the IGN switch the engine would fire and all electrics came back...After I replaced the IGN Switch I took the old one apart and found the contacts were covered in a black soot...The reason for the soot was water intrusion into the switch!

 

it's the ignition relay, key switch or wiring harness. Since it's random it's probably were a mechanical connection is made. Hard to believe you have spent a $1000 and it's not fixed. I realize there is a lot of parts on a Harley but only a real few make the motor actually run. You need a new mechanic. At that many dollars, I would think a part changer would have hit it by now.
