I put a rebuilt alternator on my M923A1 it did not have one. On the bench the alt read 24.3 volts, put it in the truck and looked at the gauge and it showed in the yellow about the middle. Well knowing what the alt was on the bench I just ran it in the truck for a few weeks. Truck ran fine, never had any issues, even running full lights. I tested power at the batteries and same readings 24.3 pulled the gauge panel out and pulled the single wire that goes to the gauge and tested it there and it was 24.3 So I figured it must be the gauge so I bought a new one, not used.
Installed the new gauge started the truck, and the needle went right to the middle of the yellow. So volts read 24.3 at the alt, the batteries, and at the gauge, but the gauges still show middle of the yellow. Looked at the TM's and they showed to check everything that I checked. Has anyone ever heard of this where it is showing the correct volts even at the gauge wire but still shows low charging at the gauge.
Thank you for any help.
