42RH OD and LU testing

The pressure switch itself can only complete the circuit when the pressure increases enough to close the switch. If it’s an adjustable pressure switch it can be adjusted to close based on the speed you want the OD to activate. I know....I know....you already know that..lol.

Lol. I don't have a vacuum switch, so I'll double check the power on the middle pin..I so have the toggle switches for LU and OD, in case I want to turn them off. I'll check the continuity there also.
