I have a 1965 Chrysler 300. It was experiencing over charging and under charging. That problem has seemed to be fixed. However the voltage meter on the dash is no longer working. It was taken apart and the back of the volt meter was fried. it looks like there was a short of some sort across the board. On the board is a volt delimiter much like those found on my 70 Cuda and challenger. The question is what should the output of the volt delimiter be on the 65? I don't want to assume it is it is the same as the 70s. I could not find it in the repair/service manual.

65 Chryslers had voltmeters?


If you are referring to the instrument panel regulator, these "pulse" like a blinker. Because the gauges are slow to react, you don't see this pulsing in the gauge action. I think pretty much all of them are close to the equivalent of 5V, Ford or Mopar.

On a '65 the "Alternator" gauge is wired directly to the Alternator. In the engine compartment at the bulkhead, check the connections of the lone black and red wires. They will be on a post style connectors between the Engine Harness plug and the Forward Lamp Harness plug. You may have some corrosion on these terminals which could be causing a short. Also check the Fuseable Link. Are you sure the Alternator is good? If you disconnected the red and black wire off the Alternator gauge it will not read. It is a separate gauge from the main cluster. These are just the basics. You should post your issue on a C Body specific forum such as:

or
www.moparfins.com

There are a lot of knowledgable guys on these boards that can help you with what I believe is a one or two year only wiring design. Both of these boards were a tremendous help in the restoration of my '65 300 'vert.

Good luck!
