    Have all the WSM and wiring, which includes the legend page for the A/C schematic #28, that schematic is not included.

    Trying to chase a no voltage signal to operate the compressor It works when jumped, the tri pressure switch on the Rec/dryer is OK.

    Big thanks for any info

    Thanks Chad, we have replaced that switch and bypassed it, on these it is an integral unit for hi and lo pressures, mounted on the reciever/dryer, that was replaced as well as the compressor.
