XR400 - electric fault finding without starting the engine

[masehare]

Hi Guys, I need to check why the one rear indicator isn't working on my XR400. I suspect a broken wire on the loom for the rear cluster. For troubleshooting purposes, how would one go around powering the electric system without starting the motor?

Cheers
Christo
