I've noticed the last few days that the scanguage is telling me at first start up in the morning, that my voltage reading is at high 11's low 12's eg: 11.9v. This is while it's still idling in the shed.
Once driving it goes up to high 13's.
Is that normal??
Should the alternator be throwing out high 13's low 14's from the very first second?
Could it indicate that the alt is on the way out??
