Electrical Disaster

There's a main fuse which will be separate to the box of fuses for individual circuits but I don't know where it is on you bike. Thing is, for any of the fuses to go it with have required many Amps of current to flow, and if that is happening the wrong way through the circuit things could be very bad.

Edit: It's possible for things like the ECU, ABS unit, and instruments, to have a protection diode inside them which will short out any reverse polariy supply and blow the fuse for that circuit. You should check every fuse in the system.

 

Thats what I always do, blame the son!!! Seriously, I hope that it's only fuses that have blown, best of luck.

 

Have you managed to find the main fuse?
