He mentioned it: The main fuse inside the power box on the right side of the cab.
Op: the lightning strike probably took out your varistor as well, open the power box and check. If it hasn't, unplug power to all boards, replace main fuse. Turn on game, and plug in one board at a time until the mainline fuse blows. This will tell you what board(s) have the issue.
