thank you

 

will the bike turn over or start and run fine. just a lighting issue?

 

Bike will not start @ all no power

 

ok this sounds like your main circuit breaker or main fuse (sorry can't remember which is on that particular bike)
have you verified that you have excellent ground connection at both ends of the battery cable?

The connection are good @ the battery thank you for information hopefully this is the problem

 

pay special attention to the ground wire on the battery where it attaches to the frame. That MUST be a good solid connection free of corrosion.
