On my 89, there was a 12v to 5v mechaNical device, for the fuel and temp gauges.
These started reading more and more bizarre, and when i put digital voltmeter on me device it was far too confused to read average voltage.
New device was 35$+
New solid state IP68 voltage bucker was 7$.
Once added i could raise and lower the gas and temp gauges with the buckers adjustment potentiometer. 0.3v difference is a full hatchmark on fuel or coolant temp.
Later, When i noticed abnormal readings, i attached a compmuter fan connector, and 5 digit voltmeter. 5.2784 has my teml gauge reading a hatchmark above normal and fuel easily 3/4 of a hatchmark.
5.0031 and it reads normLal.
Now.i just leave red voltmeter connected, and tilt it down at night. The bucker usually is within 0.05 of 5v even, but sometimes decides 5.274 is reasonable.
Whenever i see gauges reading high, so does this voltmeter.
I used to keep the adjustment pot accessible with jewelers screwdriver velcroed next to it, but that became unnecessary work.
