If you are using a meter put it on the bench.Get a tet light and see if it lights.The meter can lie to you on voltage.I had a 90s Mopar that wouldnt charge.Folled the flow chart with my meter.Spent 6 hours trying to figure it out.Ended up the wire from the computer tested over 12 volts on a leter.Put a tets light on it and it wouldnt light as it didnt carry enough amperage to turn on the alt or light the light.Spliced a piece of wire in and it charged perfect.Rocky
