He's got something draining the battery while the key is off, he's hasn't said the alt wasn't charging. Maybe in his next reply he will update us and tell us what voltage he's getting while running.
Started with 320 wet/dry, then 600, then 1200, and 2000. Then hit it with some Mothers metal polis it took about an hour after work one day. The idler pulley is actually a polished billet item from eBay.
