Charging??

I get 13.2v at idle and 13.8 at 2000rpms. Is this good. I checked my draw when all accessories are on and it never drops below 13.1v but my dash gauge shows 12v.

Sounds good.

That voltage should keep the battery charged. I would hook a volt meter straight to the battery and see what the readings are. I like to see 13.4 to 14.2 volts.

My snap on dm shows 13.4 at idle and 13.8 at 2000rpms. Still does not drop below 13.1 with all accessories on at idle. I think im good.

One would think so! Wouldn't be the first time one of those old analog meters went south. There is a way to calibrate those old movements but unfortunately, you have to know what you are doing AND have a delicate touch! Waaaaay back in the early 70's I used to calibrate analog meters, there are three sliding weights that have to be adjusted so that the meter reads the same vertical, on each side, and upside down, and it is soooo easy to accidentally nick the winding and turn the entire movement into junk!
