Fuel Gauge Prob
 

1987 Wrangler, 4.2L 5spd

Fuel tank is new, sending unit is original, and worked prior to tank
replacement.

Problem is, with switch on, gauge on dash reads full until tank is almost
completely empty, then gauge drops down to
1/4 mark.

I'm scratching my head over this one, but I'm guessing I've got it grounded
wrong somehow.

Any ideas?

I might add, there is no rust on this vehicle.

Check the ground from the battery negative to the body. The wire can
corrode inside the connector and look OK from the outside. Use a jumper
cable from the battery negative to something mounted to the body (horn,
starter solenoid).

Jumper from battery negative to starter relay? I can think of a _lot_ of
less hazardous places to put a jumper on.

Especially since the wires on a starter relay/solonoid are hot.

The test for rotted motor strap is battery ground (or frame) to
the engine block side of the motor mount or somewhere out of the
fan and belts.
