does anyone have a wiring diagram for a chinese hawk 90cc quad
loncin engine
everything has gone wrong
firs was starter switch would blow fuse so had to start it by shorting the solonoid
then battery wouldt hold charge
then while driving the engine just died and wouldnt start with the solonoid now there is no spark at plug

 

I've never heard of this quad, but there are so many generic chinese brands out there I probably haven't heard of the majority of them.

Is this quad two stroke or four stroke?

How many pins on the CDI?

Since you have multiple problems it is probably best to solve them one at a time in the reverse order of how they appeared. So I would focus on the no spark problem first (still jumping the solenoid to get the starter motor to spin). Then fix the battery charge problem, and then fix the starter button/fuse popping problem.

You will need to get yourself a meter .
