Hello everyone, I'm new to the forum and I was hoping to get some advice from you.

My daughter's 07 LTZ 90 stopped running yesterday and I've traced it down to having no spark at all. The fuse is good and I don't see anything wrong with the wiring.

I'm open for any suggestions!

Thanks,

Mark

Welcome to the forums. :)
I guess that I'd start checking the switchs w/ohm meter.
ie: handlebar on/off, foot brake switch (if there is one), the key switch.

Still giving my ohm meter a work out, and haven't come up with anything yet. I'll keep searching! Thanks for the help.

Did you check the battery?

Yes, I replaced that first. It had been dragging some when turning over, and the new battery took care of that.

First, you ned to by-pass any and all safety features that quad has, next, I would check the cdi. THE LTZ50's are known for having crappy cdi's,but Im not sure of the 90's.
