Interestingly the pressure sensor was not wired in even though it was
in the factory schematic. It’s easy to see where is could be added
into the circuit, but clearly had never been wired in when the AC was
installed. You almost cannot see the pressure sensor. It is wired in
right under the Dolphin and on top of the AC compressor. No mating
connector in sight. It was so hard to reach I could not test it’s
continuity with my meter. The spare compressor I have shows infinite
resistance at no pressure. So I am assuming that my charged system
would show close to zero ohms. This means the compressor could be run
without pressure, at least on this truck.
Slick system. As the temperature knob is rotated warmer, the
compressor slows down. It pulls around 5 amps from the pack at max
output in about 75 degree air. So it’s not well loaded for a max amp
test. That will have to wait until summer.
This truck is becoming a keeper.
