have johnson 40hp.mod#rkl265-ser#2413557.found many short/grounded wires.done. started twice and ran smooth.sat a while.went to start and puff of smoke.think solenoid fried. friend put spark tester on both wires, no spark in lower cyl.did i burn points or maybe the vacuum switch is hot and killing cyl.will replace solenoid and need to replace worn gen. belt so top must come off.with key on, should cutout vacuum switch be hot or not? wont crank with key so sol. is probably toast. ideas? thank you all.
