Hi,
posted yesterday probs in wrong forum, anyway i purchased a secondhand running 110cc quad brand unknown. it was running perfect then one day turned it off and lo and behold it would,nt fire up, cranking over but no spark.
Anyway i replaced the plug / coil/5pin cdi/stator/ removed the black/white kill switch wire from the cdi unit still no spark just cranking over. Only thing left is the black box with fins which i presume is the rectifier. i do remember the h/lights being erratic when running ,on when they should have be off if i remember rightly.
thanks for any help

 

are you holding the brake on when trying to start? their is a safety

 

Yes im holding the rearbrake in but still no spark
cheers

 

Try earthing the kill switch wire on the cdi, some of them work the opposite way round.

 

Decided not to bother cos im getting nowhere with it so iv give it to my local scrapyard
