Help! My 96 cobra mustang (82000 miles) is eating alternators...I'm on my 3rd on this year, 2nd in one month...no mods to engine, new battery, new plug wires...the plastic regulator is also melting...if I can't get this sorted out I'm going to have to go back to Jap cars...:(

it sounds like either a short or a bad battery. Have you replaced your battery wires also?

Battery is new (1 month), wires are a possibility...the car is at Goodyear for diagnostics...is there anything you'd recommend I discuss with them? Thanks for any help.

well, the regulator melting would indicate a short or degradation in the main power cables on the battery. I would have them look for corroded wires or a short in you main battery wiring.

Thanks guys, turns out there is a TSB that reads "if the battery is weak, the alternator will continue to attempt charging the battery causing the alternator to fail"...so another new battery, a new alternator (covered under warranty), a new serpentine belt and assurance that all wires were sound, got me back on the road...kudos to the Goodyear guys in Clearwater for a great job and getting me back into my Cobra and keeping me "with the force":)

:thumbsup: good to hear thing are squared away. You would be surprised how many batteries cause failures prematurely

one thing I have noticed in my vehicles, is after a battery is used till it completely dies, the alternator dies within a year after replacement of the battery. I alway figured it becuase its life was diminished by the strain of a battery going dead.

Go ahead and change the cables and regulator. Easy cheap upgrade, wont leave you on the roadside. :)

Sorry to get on a old post but ford has allways had a problem with there plugs for electric stuff(alt, blower motor , headlight switch). I would make sure the plugs are clean and making good contact. They also make a grease to put on the plugs.

Blew the doors off a Mercedes 600 SL...I guess 150,000 doesn't buy everything.

My mother has a 500SEL and it runs good for a luxury car. But for speed you cant beat a cobra.
