Hi my name is ***** ***** you still need help on this, and also do you access to a multi-meter as you will likely need to check for some voltages and resistance checks ?

OK, I need to remove the power commander and then tell me what you have


Customer: replied 1 year ago.
done that and still have the fuse blown
Expert:  Kenny O. replied 1 year ago.

OK, those are generally the cause, has the bike ever been down (crashed) and do you have a multi-meter, (volt meter) ?

Customer: replied 1 year ago.
Expert:  Kenny O. replied 1 year ago.

Well for me to help you further you are going to need a meter as part of the diagnostic tools. I'm going to opt out and maybe someone else can help you.

Hi and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, the ignition fuse powers the red/white wire that feeds the:

  • • instrumentation (least likely);
  • • OFF/RUN switch (less likely);
  • • starter relay, starting circuit cut-off relay and radiator fan motor relay (likely);
  • • ECU (most likely).

Propose simple test would be go/no-go; i.e. remove the connector that feeds the above 1 at a time until the ignition fuse no longer blows. Then the faulty circuit/component can be identified.

It has to be posted that it is still very possible for a pinched wire that is inadvertently shorting to frame/chassis ground. Trace/check all the red/white wires.

If by chance the ignition fuse no longer blows with the Engine OFF/RUN switch OFF, then trace/check all the red/black wires all the way to the ignition coils.
