I grounded the gauge as described. I turned on power and verified 12 volts to the plus post on the gauge then touched a grounded wire to the sending post on the gauge. Nothing. It just sits there looking useless.
Does that mean the gauge is bad? Or could I have some other problem.
I used teflon tape on the sending unit and in looking for answers noticed the instructions say not to because it needs to ground. I did a continuity check from the base of the sending unit to the intake manifold and it checked out so I'm sure I'm OK there but just wanted to give as much info as possible.
I bought these gauges from someone and they were still in the boxes but had been opened. So far I've had to replace the tach and as if that didn't make this already a really bad buy, now if I've got to replace another one.
Please tell me there is another answer! Pleeeease
