Gas Gauge issues

I know I have a sending unit problem, no reading when checking with a ohmns meter. My question is my gauge,it is reading about an inch passed full. When I check the terminals on the back of the gauge I get continuity between the two terminals,is this right I can,t get the needle back to empty.I know my feed from the tank is good because of grounding the tan wire the needle moved to this position.Any advice on checking this gauge sure would be a lot of help. Oh by the way I,am working on a 68. Thanks

Re: Gas Gauge issues

Use the following troubleshooter to test the sender, wiring, and gauge.
Reading past full indicates a ground issue with the sender. Ground is at the rear pass side fuel tank strap mount.

Re: Gas Gauge issues

How do I get the gauge to read back to empty it seems stuck at inch above full. I,am pretty clear on the part where I grounded the tan wire in the trunk and yes the gauge when to full and beyond,didn,t hold it at ground but for a second. And what about the continuity between the terminals at the back of the gauge. I would have thought one would be positive and the other negative. Thanks

Re: Gas Gauge issues

Follow the troubleshooter once you are finished you will know the status of the sender, wiring, and gauge.

If the gauge is in working condition you will peg it to empty and to full in the troubleshooter steps. If it doesn't you need new wiring or gauge depending on what the rest of the troubleshooter results are.

Just because it has power to it, doesn't mean it is capable of reading the Ohm's being sent from the sender.
