Had to jump start one of my daily driver cars (1999 Falcon Ute, battery dead flat) so that I could get the Mustang out for a drive.
So I ran the jumper leads from my Mustang, while it was running, to my Falcon. Well the Falcon wouldn't turn over at all, just various clicking noises and such, so I came to the realization that I needed to hook the Falcon up to a battery charger and get at least some charge into it before jump starting.
So after half an hour on the charger I hooked up the jumpers again from the stang and this time the Falcon roared to life.
Went back to the Mustang and noticed the volt gauge showing low, so check the stang's battery with a voltmeter while it was running and sure enough I am only getting 11.89 volts across the terminals.
Immediately thought that I've wrecked the regulator so swapped it out with a brand new solid state one that I had lying around, still no good.
The charge light on the dash goes out like it should, I've checked all my wiring to make sure no wires had come loose or broken and it all looks ok. It was running at about a 13.5 volt charge before the jumpstart episode.
So I'm at a loss, did I just wreck my alternator? Anybody got ideas as to what can go wrong during a jumpstart that would stop my stang from charging??
Thanks
