Won't fire. Have 12 volts to both sides of the coil but no spark to plugs. Have new cap & roter installed. Bad coil (how do you check it)? Reference sensor? Overload relay? And...how do you check these out? Any help in heading me the right direction is appreciated.

 

I cranked the engine...no spark at the plugs or coil. How do I test the coil?

 

OK Mr. Moderator...if I replace the coil it will then run? Any other possibilitie before I spend a precious $120?
