[Healeys] Fuel gauge reading full at all times

[Bruce Steele]

Thanks Roland.  I should have also mentioned that I have a ground wire from the collar of the sending unit to the frame.  But I also did not check that it was a good ground at this point.  It was previously.

Bad ground connection to sender would look like high ohm connection and give you a 'full' reading. That's my guess anyhow

After the harness meltdown, which impacted the battery lead to the fuel gauge, the gauge has read full and there is currently about ¼ in the tank.  The gauge has been checked twice and pronounced OK.  Today I bypassed the tank-sender wire with a jumper, same result—reading full.  I removed the sender and bench tested the resistance and got 2 ohms with the float fully down and around 70 ohms with the float lifted to approximately where it would be in a full tank.  From what I can find online this is in range.  So I’m stumped as to why the gauge is reading full.  Thoughts?
