To recap: 4 months ago, temp gauge was dead. I bypassed the temp. faker, and the gauge read 1/4 after car fully warmed up. I replaced the thermostat--still 1/4. Today, I put a 68-ohm resistor between sender wire and ground, expecting to condemn the sending unit. Nope! Gauge read only a needle's width above 1/2 instead of 3/4 per Bentley.

The voltage regulator seems to be fine (fuel gauge accurate and measured 9.8v out. So, can I condemn the gauge now, or am I still (potentially) missing something? I suppose I'll have to track down another gauge or cluster to be totally sure. From the archives, a gauge this far off seems rare. I don't suppose there;s any adjustment posisble?

It's my wife's car, so I'd rather red mean red. If it were mine, I'd probably just recalibrate my eyes.

Edit: I should probably mention that I know little about electricity. I just bought a 68 ohm resistor at Radio Shack and alligator clipped it between the sender wire and the body. I did try a couple of different ground points to make sure I had a decent one.
