Water temp gauge

    My water temp gauge has worked fine for many years. Yesterday, however, it began to fluctuate radically finally settling to the far right. If I put my finger on the gauge and press firmly, the needle moves properly to the mid range. When I let of the pressure, it may stay at the mid range for moment or two but swings again to hot. I put nearly 100 miles on the car yesterday with the gauge acting this way and the engine is not overheating. Is it time for a new gauge or is something else likely amiss?

    The problem is somewhere within the gauge. I am not familiar with their construction, but it is possibly an electrical problem. When you press on the gauge does it move enough to possibly change electrical contact?

    I'm just going to throw out a guess here, if the gauge is working correctly by pressing on it, I would think it has to be an electrical contact. Possibly a ground? I would certainly start there. Or it's making contact with something else electrical?

    Series 2 gauge? Start simple - remove and reattach the B & T wire connections on the back. Also make sure the gauge housing has a good ground.
