Walt, I'm hoping you can help me as you seem to know your electrical stuff regarding Porsches. The problem I am having ('89 911 Turbo Cab) is that my oil pressure guage just started reading zero all the time. I disconnected the wire from the oil sender and the pressure guage pegged to 5. When I grounded the wire the pressure guage went to zero. This means my guage is good. However, you hinted at a test to determine if the sender is bad. Can I ask you what that test is? I've read multiple threads on replacing the sender and it's more involved than I initially thought. I'd hate to go through all that trouble (plus the cost of a new sender) if it's still good and the problem is somewhere in the wiring.
On that note, would I have a wiring problem if I got the pressure guage to peg at 5 (sender wire open) and 0 (sender wire closed)? Any help you could provide would be greatly appreciated.
