Thanks for your input to the Forum. Help please with fuel gage pegged on F. '64 GTO. What next steps?
Using volt ohm meter:
1. Key on, 11v on tan wire unplugged and grounded to ground point near tank
As above, gage needle is past F. Switching key off needle moves down from peg slightly and back to peg switch on
2. Key on sending unit terminal grounded and needle pegs F
3. Sending unit terminal to ground 74 ohm. Tank is down a little from full
4. Unplugged tan wire to ground 45 ohm.
I have spare gage pn 6430125 I think is 1965 so 90 ohm. Across the wire wound resistor between the two blades 40 ohm. Left blade to ground stud 90 ohm. Right blade to ground 130 ohm.
