Ok, on my 87 4.0L the volts read almost down into the red at idle with the a/c or lights on. When the rpm's come up it gets up to almost 14V, most of the time. I've done the alt wiring upgrades and am running 0/1 welding cable from the battery. is it time for a new alternator or is there something I'm missing?
Thanks
Keith
