I think my oil pressure switch on my 3.2 that is located on the top back of engine next to the tranny is bad.
So I am finally hooking up the wiring to my 4 gauge cluster gauge. I have the oil pressure gauge, oil temp gauge, fuel tank, and voltmeter working. The only problem now is the oil pressure switch "idiot" light not working. When I check the continuity of the green/red stripe wire from the 914 harness to the 1988 911 engine harness it checks out great. When I pull the wire off the oil pressure switch on the top of the 911 engine and ground it, and turn on the ignition the oil light lights right up on the gauge cluster and then goes off when I remove the ground. When I plug the wire onto the oil pressure switch and turn on the ignition and start the car the light doesn't light up at all. How can you tell if the oil pressure switch is bad? Thanks, Buck |
