Mark -If you find your gage regulator(stabilizer) is at fault, you might
want to bid on one of the SOLID STATE units I am selling on e-bay. I can
sell you one directly as well. see

Subject: is this the voltage stabilizer?

> Symptoms:
> 1. fuel/temp gauges do not work

> 3. even when it does not blow, I can turn on the vent fan and the fan

> This is what I have done so far:
> 1. tested fuel gauge with a 9v battery -- appears to work ok.
> 2. disconnected voltage stabilizer and problem 2 and 3 seem to go away
> (at least they do running the fan for 5-10 min.)
> 3. measured input voltage to VS -- almost exactly 12.
> 4. bench tested stabilizer with a multimeter. I see wild swings from 0
> to 5v to 7v. Nothing higher than 7v ever. I was expecting 10v.

> Am I right to suspect the stabilizer? What in the world could have made
> it go kaput just by removing/refitting the speedo/gauges?
