I have a somewhat related question:
I am trying to troubleshoot why my gas gauge is kaput. I read that often
the problem is the fuel tank sending unit. If that is indeed the case, how
do I test to see if it is the sending unit or the gauge itself? (hoping for
the cheaper alternative - sending unit) Also, when I looked at the sending
unit, there are 2 terminal connectors, but only 1 has a wire attached. This
may be a stupid question, but are both supposed to be connected to
something? If so, what connection may be missing?
Thank you,

Subject: Oil pressure sender
Hi all,
Now that the car is running I working through some electrical problems.
Managed to determine the cause of my malfunctioning water temperature
and gas gauge today (bad voltage stabilizer). Also found out I have a
faulty oil pressure sender. A couple questions:
1. What should the resistance of the sender be at rest? (mine shows
infinite currently)
2. Anyone ever replace a oil pressure sender on a '69 B with a modern
sender unit? (Or if I know the resistance I can cross ref to one)
3. One wiring diagram I have (Haynes) shows the oil gauge to be fed
power from the voltage stabilizer. Mine is fed from a green wire on the
"B" side of the stabilizer (not regulated) which is consistent with the
factory workshop manual. Since I have seen it both ways I am curious if
the oil pressure gauge should have regulated power. Thoughts?
So many questions.
Thanks,
Chris
