All tested and working great. Car runs up to temp and all gauges are dead accurate. Temp reads perfect, oil as well.
My question is:
When i turn the key "on" the guages power up-as normal
But, when i hit the key to "crank" the temp needle pegs itself violently over to the Hot side. Once the car is running and the key is back to the "on/run" position the needle goes to the correct temp, and all is wonderful, needle reads dead acurate.
Bench tested the whole thing before install, had the sender in pot of water on stove, etc, etc. the guage and sender are grounded no problems.
My question is: normal for the needle to pin over like that only under cranking???
this car had an idiot light originally but i studied all the schematics and the wiring was the same, just the sender and the conector on the back of the gauage that was different from what i saw.
The reason i ask is that my 67-72 trucks both have temp guages and they do not do this.

It's the same idea as the bulb test when you turn on your key and the "temp" lights up when you crank it. Simply showing you that the gauge circuit is good.
I wonder why they wired the pickups different? Or maybe it's just because it's later. Maybe the cars didn't do that either in later years.
