I am having trouble getting a spark out of my 400 Scrambler. Suspecting a motor to chassis grounding connection problem, maybe... What I am wondering... There is a mounting plate that harnesses the motor to the bottom of the atv chassis, if this is not connected correctly, example.( JB Welded to frame instead of acually bolted to it, I do not know why, but thats how it came to me) will that cause that grounding point not to ground? Thus causing the engine not to fire. Even though the engine has more than that one ground point. Is my theory in the right direction?

I would appreciate any experienced/expert help.
Thanks
