Your battery is kaput, and your faithful alternator was doin' all it could to charge up a non-charge uppable battery....check the date on the knock off stickers indicating the date of the first charge....five years is pretty much it. because batteries will degrade, not accepting a charge ten percent per year...so if you're runnin' with a ten year old battery will not be charging up...at all and force the alternator to run till smokin'..just as yours has done~

You need a need a battery recommend Interstate, Prestolite or NAPA because of their warranty and "pro-rate" givin' you some credit for the oldie---clean the connection from the black 1/0 battery cable to the chassis ground with a coarse wirebrush and check the connection to the starter solenoid with a smaller brass brush....turn the key...keep your fingers crossed that Altie wasn't cooked and be prepared to remove it as a core for your replacement unit...should be under a hundred bucks for a remanufactured one~
