I noticed while driving the bat indication on the scan master dropping to upper 12's low 13's do I went out dnd did some checking. Engine off car had been setting a week or do battery showed 12.25 volts. Cranked it up
And I had 14 at the battery and 14.4 on the alternator stud to ground strap at the back of the engine.
The scan master showed 13 to 13.7 kinda erratic ..,
Is there a problem or is this normal . Scanmaster seemed to steady out after running about 10 minutes at 13 to 13.25 volts.
