New here and hope someone could help..I know its not a (bike) .I have a quad with a 350 Yamaha engine,It starts when pulled but when I try the electric start it has no spark at the plug Any help appreciated .thanks

Thanks for all the replies chaps .Very informative

I had a similar problem once with my old XJ550 Seca.....

It ended up being a Starter Cut-Off relay .......which I cured by installing jumper wires across the connector to that relay......in effect by-passing it........rode it like that for another 6 years before I sold it.

Your Quad might have a similar circuit.

BTW.... to the forum

Sorry for the delayed response
