[QUOTE="Imatk, post: 16162135, member: 75573"] I would probably first check for parasitic draw. You can do this with a 30-dollar multimeter. If you don't know how there are plenty of youtube vids that show how to do it... but basically you set the meter to amps and then disconnect the negative terminal of your battery and touch the negative probe of the meter to your now disconnected terminal and the positive to your battery. If your reading is higher than 80 milliamps then you have a problem with a short. From that point you need to start pulling fuses. Fuse, by, fuse until your reading falls into a normal range. Once it falls whatever fuse you pull is the culprit and then you go about finding that circuit. It sounds difficult, but it isn't. If you don't have the issue at all though, that's a very fast check to make sure... meaning if your meter reads 80milliamps or below you know you're good, and it's just the alternator. You might also have an issue with the alternator ground, and or power wire. Again you would need to do a test on those lines to see if you have any voltage drop from one end to the other. My GUESS is that you just need a good alternator (I went through three before I bought my Nations alt) but 30 bucks and an hour or so with a meter will save you some money if it's some other culprit.
