When I bought my car, Ross Miller checked it out and as part of the inspection told me my voltage regulator (VR) was not charging correctly. He adjusted it and I was on my way. Here it is a couple of years later and the ammeter gauge was fluctuating wildly. I had a new VR so I decided to install it.
As part of the testing, I had to make sure my battery connections were good and the battery water levels were correct. Well, the cells in the battery were half full! EEK! So, I filled them with distilled water and went for a test drive. I checked battery voltage when I returned and it was 6.25 volts.
Here is what is happening and I was wondering if it is "normal".
At idle, the gauge is just slightly to the left of the center of the gauge.
When I drive, and use the turn signals, there is a big swing to D.
If I turn on a small draw like the heater motor, it almost pegs to the D.
With the engine off, and the ignition on, the needle is little to the left of center.

Data
Specific gravity all cells 1.300
Voltage at terminals 8.4v (after overnight charge)
Amp Clamp readings
AMPS
With just heater blower motor on 5-8
Headlights only high beam 18
everything including radio 38
just turn signals 5-10
Question: Is the ammeter working right?
