Hello, The first thing I would check is the cooling fins on the cylinder jugs. There is a little circuit board inside those coils and extreme heat will take them out. The cooling fins need to be clear of dirt and debris so air from the flywheel can pass by to cool properly.

Also there is a wire that connects the two coils. There is a Diode in that wire so current can't flow back to the coils. Sometime Mice chew threw the wires and customers will just replace the wire not thinking or knowing about that diode in the wire.
