I just installed my console gauges over the weekend. They were working fine up until Tues night. I wanted to run my car out of gas to fine out how true the thing read. I did. After adding a couple of gallons and restarting the car the gauge went all the way over and off the scale on the full side (I haven't filled it yet) I just checked all the connections. It is grounded and has power, I even turnned the gauge upside down and let the needle fall back to E. As son as I turn the key on it went back to way past F. It is a brand new OEM console gauge set.
Bad gauge or did my sender or wiring from the tank go bad. Pretty strange timing if it is the latter.
Any thoughts on how to test the signal from the tank?
