I have a 01 polaris scrambler 50 & I cant get the thing to fire. When I pulled the plug & grounded it to the case it didnt make a spark when being turned over. Does anyone know how to test the coil to see if it is bad??? Or is there anything else I should be testing??? Ive already checked the basic wiring to make sure everything was plugged in, key & kill switch, etc...

Also there is a black plastic peice that goes down into the top of the carb with wiring coming out of it. I found a parts breakdown & I think it listed that peice as a starter plunger, what does it do??? could it cause the bike not to fire??? is there a way to test it???

Thanks!!!
