Hoping someone can help me with finding a short. I have a VESPA LXV 150 and the main fuse blew out 3 times while driving the bike. Each time the bike completely stopped working.
- Engine died
- All lights and functions went out

I am using a 15 AMP main fuse which is what was in the bike when purchased and seems to be the correct fuse

It seems odd to me that the engine would stop running when the fuse blows. This leads me to believe the short is in the ignition. Can anyone confirm my assumption and the best way to test this?

Thanks
David

shocking
hi buddy,
you have one serious short there, i suspect it is the main battery lead chafing the bodywork.
look at the wiring diagram on wiki and follow the circuit.
cheers Andy

Thank you. I appreciate the info. It just seems that the motor would keep running for anything other than the ignition, but I guess it could be before the ignition. Anyone have the schematics for the LXV150?

I've asked before - but no-one seems to have the circuit diagrams for the LX or LXV125/150s. It can be purchased for a few $ from AF1racing.

If anyone *has* got the proper pdf to hand, I'd be grateful if they'd email it to me so it can be included on my website (which will be undergoing a change soon. ).
