Gauge Cluster Issues/IVR
I just resistance checked the three gages from my 67 Barracuda.
Each one was 20 ohms.
In operation; the fuel gage worked, the temperature reads low, and the oil pressure seems high.
Measurements in the engine bay had indicated to me the IVR output might be seeming resistance.
So even though the circuit board looks pretty good, before removing the gages a resistance check in the line was in order.
Using probes tips on the board itself shows it to have no resistance.
So one issue must be the oxidation on the studs and PAL nuts.
I don't know if this may be applicable but seemed like it might be.
