I was in a hurry the other morning trying to get ready for a bowfishing trip with my son and hooked my motors (1979 Mercury 500 Thunderbolt 50HP) negative battery cable to the positive terminal and my negative accessory wires (including my closed kill switch) to the negative battery terminal. I heard a pop at the motor (guessing the switch box) and now the engine will not even crank. Even the choke switch does not click when pressed? Would a blown switch box prevent the motor from cranking and the choke from engaging? Just need confirmation or diagnostic steps before I order a new switch box or take it to the shop.
Thanks
Mike
