the auxiliary power valve. This is a safety type switch
to make sure the auxiliary power valve is in the
neutral detent (Fig. 088).
1. Disconnect the switch from the wiring harness.
Leave the switch in the Auxiliary Power Valve.
2. Using a VOM multimeter (ohms setting) there
should be continuity between the two wire
terminals.
3. Leave the Multimeter (ohms setting) leads
connected to the two wire terminals. Move the
auxiliary power valve handle to either the reverse
flow or forward flow position. There should be NO
continuity.
