Also - can I have a blower motor and a three speed wiper checked for proper function before I clean up and re-install ? 7332682-P1090816(Small).JPG (80 downloads)

Bypass it. Right is a condensor I believe to help protect the reg from voltage spikes that would fry it live every 24 hour block of time like it's your last day on earth

Jump 12v positive to the blower motor hot wire and 12V negative to the case & if if turns with no grinding/excessive noise you're good. live every 24 hour block of time like it's your last day on earth
