I'm looking for some help on the next steps for troubleshooting.

'37 Chevy 1/2T

Ammeter was always showing above 0 bouncing around and seemed to dip (left) with headlights and / or brake lights illuminated.

Now the meter reads straight up zero with the vehicle running. It will dip (left) with above lights as well. Truck off the gauges falls completely left.

After charging the battery fully, I started the truck and measured 6.5 - 6.7 VDC at the output of the regulator.

Where should I go next?

Thanks,
Justin

My Grandfather bought it new and Dad drove it through highschool. The 3rd & 4th generations put it back on the road on 8/8/2015!
