when I start my 66 the temp and oil gauges move all the way to the right and stay there, the amp and fuel do not move at all any ideas? thx

 

Possibly a short? Or not hooked up correctly?

Has it been running right? Have you changed anything?

 

runs fine.

 

The temp/oil/fuel gauges are fairly easy to troublesoot.

Pop the hood, turn the key to the on position, but don't start the car. Disconnect the wire from the temp gauge on the intake manifold. Ground the end of the wire to a good known ground. Watch the guage. As the wire is grounded, the gauge will sweepall of the way to the right. This test will work for oil/temp/fuel gauge and verify if the gauge is working.

Since your oil and temp gauges are already doing this, I suspect that you have a short somewhere as these 2 gaugesare both sensing a full ground.

Try grounding the one wire connected to your fuel sending unit back at the gas tank? Does the fuel gauge sweep to full? If so, your gauge is fine and the sending unit (inside the tank) is bad.

how do I fix these ground problems? thx.

 

You need to follow the wires, to look and see if anywhere along the wire the sleeve has been rubbed off/down to the wire.

 

check wiring,,, theres a 5 volt volt reg above the speedo or so... runs the gauges
