possessed temp gage

Postby azruss » Thu May 18, 2017 3:38 am

When i restored the car, I picked the best of 4 temp gages I had. Everything went fine until several months ago. It would read fine, then gradually increase, then drop down again. I just thought the stat was opening and beginning to stick. It would also jump 20 degrees when I turned the lights on....ground issue?
So lately, it would get to temp and stay there a while, then start to go up and would peg in less than 30 seconds. Increase was too fast for it to be a cooling issue. I stuck my finger under the dash and wiggled the gage wiring and it would immediately drop down to normal and start the whole process over again. Now when it dropped, it showed a lower temp than it every had before. 195 vs 185. So i replaced the gage with one of my spares. Now the temp sits at 185 and steady as a rock.

Those cheap infrared handhelds from Harbor Freight and others are a great sanity check. I carry one in my tool kit.
