still no air!! put on a set of gauges to confirm system was charged. gauges read a static pressure of around 110 on the low and high side. I think this is in the ball park, since today was around 90 degrees. since the clutch does not engage, the pressure doesn't change when engine is running. found an electrical wiring diagram in the manual, of course the wire colors don't match what is actually on the MH! anyway, found the location of most of the air conditioning parts. with the key switch in the IGN "on" position and the air conditioning selector switch on "max air", I traced the 12v
to the thermostat, low and high pressure switches. all seem to be working. the output of the high pressure switch, according to the wiring diagram, goes directly to the a/c clutch, and engine processor. the a/c clutch connector does not have 12v
. I applied 12v
directly to the a/c clutch, and the clutch engages. I assume the 12v to the engine processor is to signal the engine processor to increase engine speed due to the clutch being engaged. my question is, does the engine processor also send 12v to the a/c clutch on a different wire? does anyone have a ideal where the engine processor is located?
