At random, my bike shuts down electrically. No radio, guages, or nothing, it just shuts down. I wait a few min. and everything comes back on. I know it's heat related because thats the only time it does it. I checked the dealership and they told me that the main circuit breaker had been replaced. I really need some direction on this....please help?

 

probably the main breaker.

circuit breakers are tripped by heat- meant to be the heat of current flowing through them, but proximity to exhaust etc. can play a factor

circuit breaker reset themselves when they cool down, they do get "weak" and at that point need to be replaced.

have any accessories been added which would increase the load on the electrical system- extra high power lights for instance ?

You could rig up a test light or LED to the load side of the main breaker and if it stays on when the bike dies- then you know the breaker is fine.

next is the main ign. switch.

these do fail, the contacts burn and pit if too much current goes through the switch, esp. if extra lighting is added up front.

wiggling the switch will often result in the lights etc turning on and off if the switch is on it's way out.

Agree with mkguitar. The 03 faired touring bikes had a main circuit breaker issue. The fix was to replace it with a 50 amp so I'd check there first.

 

Thanks Pal, I'll try the test light and see what happens!

 

Don't just replace the main CB, you also need to put on a thicker terminal on the silver stud, it is part of the service pack to change the breaker.

 

Has a friend with the exact same bike and issue. He changed relays, fuses but it continued to do it. Finally he changes the battery cables and that solved the problem. The cables looked fine but had suspect there was corrosion at the terminal ends.
