Hello all! I am currently restoring a 79 Shovel and I've hit a snag. I finished it about a week ago and it was running fine and all the sudden I have no spark to the plugs. I sincerely believe it's not the points or the coil. My question is this. Can it be the 30A main breaker coming off the battery? I've seen that it runs directly from the batt to the upper controls to the coil. Any insight would be helpful.

 

A circuit tester is your friend. You might want to direct your questions to the Shovelhead forum.

 

if that shovel has the factory electronic system still in it. swap it out for points.
