Gas Guage Issue

Gas guage is almost on full. Sending unit ohms are within range (0-90) have continuity to the fuel gauge. When I ground the tan wire to the sending unit the guage doesn't move. NO isuues with ground. I am totally perplexed!! WTF

Do you have the key on when doing this?

Re: Gas Guage Issue

When checking ohms-no when grounding the tan wire-yes.

Re: Gas Guage Issue

If ground is on the tan wire, the gauge should go to empty.
No empty, bad gauge.

Re: Gas Guage Issue

If I'm reading ohms from the guage does this still mean its defective or could it be the guage resistor?? How would I test that?? are there perameters for this??

Yes you can test the resistor using your meter.

Re: Gas Guage Issue

what range of resistance would I get?

Re: Gas Guage Issue

If you are running an AC-Delco factory fuel gauge you might have an OEM (thin wire wound around fiber or plastic board) style resistor and it should read aprox 40 ohms plus or minus a few.

If you have a replacement OER fuel gauge there is no resistor - its built in.

If you are running a Classic HQ reproduction fuel gauge you need either an original style wire resistor or a replacement style "shunt" made of ceramic material.

Ceramics are 45 ohms,
