Gauge Cluster Issues/IVR

Sad and unfortunately all too common situation.

I'm going to leave the IVR and gages alone assuming they pass the remaining tests. Since the fuel gage worked OK, and the oil and temperature senders were getting less than 5 Volts (need to find my notes on exact number) I suspect the problem is in circuit resistance. I need to prove or disprove that.

The mechanical limiter emits a pulse voltage. Analog meter will show something like 5 to 6 volts at senders. Digital meter will show the 2.X, 3.X pulse that averages 5 to 6 volts.
