I have a reducer on the gauge. I put a meter on the gauge side of the reducer and with the key off or on I get no voltage.
So I put the meter on the hot wire side of the reducer and I get 12 volts with the key on and no volts with it off.
It appears to me the reducer is bad.
I jumped out the reducer and the gauge went to full with the key on.
It returns to 1/2 when the key is off. It appears the gauge may be stuck and can’t go below half. It used to float a little when driving before the 12 volt conversion.
I also grounded the sender side of the gauge and it stated at 1/2. Didn’t even budge a little.
I called vintage auto for a new reducer. Should I put and aftermarket gauge in. The in dash gauge is only 10 or so years old. Replacing it is a nightmare.
What’s a good after market gauge that will work with my sending unit. I believe the sender is 30 ohm. I bought it from LMC truck with the gauge.
Thanks
