Looking for info on a very old Starcool system
1990 Ford E250. It has an early Starcool system that piggybacks on the dash A/C's blower and evaporator.
The dash A/C works OK while driving. When the belt-driven compressor kicks in, so does the fan on the extra Starcool condenser under the driver's side door.
What doesn't work is any of the shore power stuff. When I turn on the 20A breaker and turn down the thermostat, there's a quiet click from the relay box under the rear seat, but nothing else happens.
Found lots of info in the forum, but it's mostly for Starcool III, which is different from my system. I could use a schematic, because the wiring is surprisingly complicated.
