Ok, so I brought different multimeter (fluke) I checked the battery 12.7V, checked alternator lug same voltage, started the car, slow idle 13.4-13.8V, if I rev up over a 1000 rpm ( just guessing) it’s stabilizes at around 14.8V
I think I’ll leave it for now, I’m happy with that. At the idle of I turn lights and fan on it’s not enough juice produced so it’s draining battery, but if I bring revs up, it’s all good. I think I’m happy for this portion and on to next thing. I need new brake lines, changed master already, electrical wire change as needed, steering box adjustments, full on suspension bushings, leaf springs, carb rebuild or replacement, possibly rear end rebuilt, new exhaust and manifold, and lots of rust repairs lol
