Fuel Level System

Hi Folks, Have seen several threads on this subject. Here's what I have. Fuel guage pegged at 3:00 position. I know that this corresponds typically to a poor ground. But when I ground the tan wire at the sending unit to the frame, the guage stays pegged. Does this mean that there is a disconnected tan wire somewhere further upstream towards to the firewall and instrument cluster? Has anyone run into this before and what was the outcome, before I start tracing wires. Thanks

Re: Fuel Level System

Have you tested the wire from trunk to gauge for continuity?
It is a single connection trunk to gauge. You can test the gauge on the bench by using different ohm resistors on the tan lead to mimic the sender once you confirm the gauge is working. You can bench test the gauge and ground the tan lead to peg the gauge.

Re: Fuel Level System

Thanks, I'll give that a go. Might also try and just ground it at the guage lead to rule out the guage itself. It has to be in that run somewhere between the instrument cluster and the sender.
