Repairing Temp. and Fuel gage Indication on a 1969 Dart Swinger 340

Cubzy said

Hi All,

Today while out for a nice drive I lost indication on both the Engine temp indicator and Fuel gage at the same time. What do both of these instruments have in common. Perhaps a power supply or a ground connection? Connections on intake and gas tank are all good. Everything worked fine up to this point. What should or I check? I'm thinking its a corroded connection?

Thanks in advance.

Even if it is a bad connection, upgrading to the solid state device is simple and safer. I am told. dont quote me.... that when the mechanical VR fails, it fails in a way as to deliver 12 volts constant. This will kill your gauges as they require 5 volts.

I took a simple trip to the local electrical supply house and bought all the necessary components for less than 20 bucks ( I have enough supplies to make 5 VRS)

It was a fun project and it works like a charm.

Let me know if you get hung up...... I could probably pop a set of ingredients in the mail for you.
