[Healeys] Fuel gauge reading full at all times

[Bruce Steele]

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?
