So as much as I love beating on this dead horse...
67 Newport base, 383, auto.
The car came with a new sending unit installed but the gauge never read full. I had another, supposedly better sending unit installed just over a year ago and it worked great for about 2 tanks of gas and now it has the same issue.
It reads almost half when really it's full.
I can ground the wire from the sending unit and the gauge will go all the way up.
I sink tested the "old" unit and it works fine. I hung that under the car and hooked it up, moved the float but same result, only about 1/2 on gauge when it should be full.
I've got the gauge in my hand and I can put 4.5v across it and it goes full.
I'm trying to test the voltage limiter that is tacked on behind the gauge but not sure how. I assume 12v goes in and 5 out?
If I put my 4.5v in I get 4.5 out. 12v in and nonsense readings out.
How do I test the condenser?
Really getting tired of the same old horse....I've got $300 into now...and many of my own hours now too..
