No Spark

[phild]

Hi Folks I'm looking for some advice re a problem on a quad bike not my Storm.

I think I have narrowed the cause of it not sparking down to either the coil or the cdi unit with the cdi being fav, but as they want over £250(ouch) for a replacement I need to be sure.
There may be a clue to the fault in that when I leave it overnight and charge the battery to full then try it again for a couple of turns there is a good spark and it will even start for a few seconds then dies and then its no spark again. Have checked all the readings from manual for the electrical tests as best I can but nothing conclusive is showing up.

Have replaced plug and plug cap already!

Its a Polaris Sportsman 335 1998 model if anyone can help?

Cheers Phil

try it with a different battery before you go spending silly money.
could be the old r/r failure - it doesnt just happen to storms you know
