Fluttering Voltage, Backfire, Engine Quits

Thanks 67Dart273 for your quick reply, as well as your suggestion KitCarlson. I did just that and started going over major connection points, starting with the battery, then bulkhead connector. Then got thinking about that rattling alternator, so checked it and sure enough........a wire, i think Ignition wire had jumped off the FLD terminal and had been touching the outer case of the alternator. Upon closer inspection of the alternator, I could see melted wires within the alternator so just picked up another from the local parts store. I am assuming this was the issue, but wont be able to get the alternator back on until this weekend. I will be sure to post my results though once I get it back on so hopefully others can benefit from my experience and save a ton of time looking, or better yet.......be proactive and make sure those connections to the FLD posts are secure. Had that wire stuck to the alternator case, things would likely have been much, much worse. I'm feeling lucky.
