Do I need a new alternator?
Have a 1999 F250 7.3L diesel with an alternator issue. Alternator crapped out about 11 mnonths ago, replaced it without any problem. Did have a little intermittent battery light, nothing much - checked the output (batteries and alternator) and figured there might be a loose connection somewhere but couldn't find it and am a complete amateur (trying to learn). So last Friday, truck pulls in to the driveway and battery light on all the time. The batteries were brand new three months ago (Interstate). Took a reading and they were lowish so put them on charge. Noticed that the alternator connector was loose so pushed back the rubber boot and almost as I touched the nut, it fell off in my hand. I took off the alternator to get a better look and it looks like it had melted or something. See below, the piece that fell off is sitting in the middle. The question is, can it be mended or should I get a new one?

In the pic the alternator is on it's side - left front is where the connector cable attaches. The red housing has black burn marks on it and is warped/melted. The screw post inside is sheared off (nut with the remaining screw part is on the white circle in the middle of the pic). I'll take it back to NAPA and see what they say - bought it about 11 months/1 year ago. don't know where the receipt is though

No high drain devices. I think maybe Senix had the right idea. I took the alternator back to NAPA and they confirmed I bought it in June last year and replaced it under warranty. Slapped the new one in, no problems, no battery light. Batteries were reading 12.38 with engine off and 13.8 with engine running so we're looking OK right now I think. Thanks for everyone's comments. Now on to the brakes and calipers!
