I'm having nothing but trouble with my rallye dash gauges. The only one I know works for sure is the ammeter, at least it moves when I use a blinker. How can I test the fuel level, oil pressure, and water temp gauges out of the car? Is it best to test them on the circuit board or remove them and test seperate? All I have for testing is a cheapo volt/ohm meter and a power supply.

I think the Moparts tech archives have the information. The first test would be to check for a slowly pulsating voltage on the wire to the sending units. It should average about five volts.
