OR Classic gauge and cluster going out of business

I had the same problem with my old cluster. The needle is on the discharge side when the truck is running, but I have 14+ volts at the alternator and the battery.

Thanks,
Mark

Hi Mark,

Are you running the stock wiring for the gauge cluster? What you describing sounds like the #1 and #12 terminals on the cluster connector are reversed.

This is pretty straight forward. One wire comes from the junction block (battery side) and goes directly to the cluster. The other wire goes from the voltage regulator (alt side) and directly to the cluster. One wire is black and the other is black with a white stripe. I believe 20 gauge.

Are you still running the stock external regulator? If not, get with VetVette and see if he can help you with the wiring for the amp gauge. I am sure it does not work the same if you have an internal regulator alternator.

Funny it is 14 on both sides. That should make the needle neutral (middle) of the scale.

I can send you another amp gauge if you need it but it sounds like a simple wiring problem.

Hope this helps.

Take care,
Tom
