Electrical short?

My 08 CBR1000RR is having an electrical problem. The headlight is usually not coming on when I start the bike. It may come on when hitting a pretty good bump. If I use the turn signals the bike stalls. My electrical troubleshooting skills are really limited... Any ideas on what to check for this issue? Thanks!

Ok, no responses. Anyone know where the ground connects to the frame?

You can follow the Neg cable from the Battery and it should connect to the frame. That would be the main ground.

At 12:10 in this Bazzaz install video it shows the ground lug that is under the tank. There may be more - I don't see a thick battery ground on it:

Check that none of the connectors on top of the airbox are loose.

Do you have power to your high beam low beam switch? Sometimes the switch can get corroded, and your headlight wont work.

Thanks for the ideas. Checked these out and the inside of the headlight switch looks a bit nasty. Weird, I've only got 62k miles on it. I'll pick up another one on ebay and see if that takes care of it.

The replacement switch came in but did not fix it. I'm going to pull the tank and dig in to the wiring there a bit.

Hi KirkRoy,

I believe you have two issues here.

have you checked the power at the headlamp bulbs?? If you do, then apparently the bulb is bad. if you do not have power, you have to trace the positive cable until you get to a point where there is power, it might be a connector, a relay, or a broken cable.

the starting issue might have to do with the headlight. there are a few threads on bikes not starting. find one that has a trouble shooting process and dig in.
