Since I replaced water pump, belts, hoses, thermo I've had a 'pulsing' temp gauge. After reading posts here, I replaced cap, both sending units, and another thermo. Same problem. I learned to ignore it.
NOW, TODAY.........
I looked down and the temp gauge was almost pegged, but motor was running fine. I watched briefly, then turned A/C off. Not only did gauge drop to 'normal', it dropped IMMEDIATELY.... I knew A/C could not have truly affected temperature that quickly.
I then started experimenting with fan switch. I figured out I could make TEMP gauge go up and down by FAN SPEED, regardless if it was simply on vent or A/C (no difference between the two).
After my next stop and restart, it was 'fine', and I had no issue with temp gauge regardless if fan was on or off.
Does dash have a separate voltage regulator?
ANY STARTING POINTS? This one was weird enough to post for input.... Thanks,
