Hello,
I have a 1999 Sportster 883. After leaving it sit for several weeks (ran fine) when I turn the key on there is no lights, start, turn signals, etc. I tried a battery out of another bike that runs fine and no go. I also, at the recommendation of the dealer replaced the circuit breaker. All 15 amp fuses are fine.

Any thoughts?? Thank you!

 

Try the relay, mine was a hit and miss item. Worked sometimes and not others. Auto Zone about 9 bucks.

 

Are you saying no power when you turn the key? if so, be sure your ground connection on the frame is tight .

 

I tried a new relay, and the ground connection is tight. No go unfortunately. Could it be a battery cable? Not sure where to go next.

Thanks again for all the ideas!
