Hello, friends. I have a 54 Crestline V8 and have a little prob with the temp sender and gauge talking to each other correctly. The car has been converted over to 12 volts. Should I have the 6 volt temp unit in running up to the volt reducer or should I have the 12 volt sender in? Car came with the 6 volt temp unit and no voltage dropper and the temp gauge was acting weird and riding all the way to the hot side even tho the car was not running hot. My mechanic worked on it some using the old 6 volt temp unit and installed the reducer at the gauge. It does not rest on hot like I have heard they should when working properly. He told me that he did some calibration with the gauge but it is not acting right. After driving, the gauge needle stays in the same position as it was in when the car is turned off. Then when you hit the key it goes down to the cold side and works its way back to half way or so even when the car is cold. Any tips would be appreciated. TY!
Sender don't know 6-v or 12-v, it just goes to ground. To much thread sealant can screw that up. A Runtz regulator at the power in to gauge is all you need. So power to Runtz from Runtz to gauge from gauge to sender and sender grounds it all.
Thanks, Wizz. We have the 6 volt temp sender in and have a good reducer installed at the gauge. I will take a look at the sealant- if any was used. My buddy said that he worked with the calibration of the gauge so Im not too sure what that would do or not do for me.
I have no idea how anyone would adjust a gauge or why. You might disconnect the power wire at the gauge and see where the needle parks itself. That's where it should live until you start making heat in the motor. Same system as my 51 Ford.
Thanks, Wizz. I will take a look at the power wire idea just to see where the needle rests. Thanks much.
I would also like to know how he adjusted the gauge.the old saying********* baffles brains comes to mind when he says that
