I didn't quite follow all of that, but I'll offer a couple of experiences with a Rule
switch that I recently replaced.
1. The old switch showed continuity when tested, but it had a high internal resistance, so the motor
did not get enough current
to run. (Mine was one of the old mercury
2. The old snarl of spliced wires in the bilge was utterly repulsive, in more ways than one. It seemed to me that the proper way to deal with serviceable equipment
was to connect everything at a terminal block high and dry in the engine
compartment. No splices in the bilge. This makes troubleshooting and maintenance
a lot quicker and easier.
