you now should have an alarm,3 bars flashing on the tach and 180 seconds of transfer.
if switch SWB,remote tank level, is bad or the wiring is bad NO automatic transfer will ever occur and the center bar or yellow lamp is illuminated.
that enine you can test the engine oil tank switchs with key on engine off UNLESS it has the updated oil control module that has a green/white wire going to the pulser coils.
No green/white wire, just white, brown, black and red.
When you say switch are you referring to the control unit?
