Re: Gauge Cluster in and Functional

I figured out what the problem is, there is a ceramic resistor or something on the back of the guage that is shorted out, causing more than full ground to the guage. It points to full right when powered. I ordered a new one from the dealer today.

Good job.

It sounds like the shunt resistor burned out on the gauge.

I threw together a quick table showing the gauge reading based on the resistance sent to the signal lead from the oil pressure sensor. It also shows the reading for an open (unplugged) and a short (grounded) conditions.
