2004 270 Sundeck 8.1, accidentally touched the wrong battery cables together when installing a new battery. Stone dead at ignition switch and resettable circuit breaker next to engine ECM. I hear of a fuse on the starter, which is virtually impossible to reach, and a 15 amp ignition fuse on the purple wire. Any idea where that purple wire ignition fuse is? The little fuse box in front of the helm is dead, and if I solve the other problems, I suspect I will get that back. The Perko switch is sending good power to the big battery cable going to the starter, but I can't reach any of the other wires around there. I'm going to build a 12 inch probe extension. Of course, I have a trip to Lake Powell in a day, with people flying in from Maine and Illinois.
