Dean,
It sounds like your wiring my have seen better days. If the wiring fell
apart on the switch and then on the solenoid, your wiring may be very
brittle. You could have a broken wire in the middle somewhere. It may
be
a good idea to ohm out the wires to be sure they are good. Wire is
pretty
cheap.
