Re: Lsx swap with some electrical issues.. Help!

Ok, this is making more sense now. So you have the alternator wired like stock, controlled by the PCM, and it's charging correctly? This is what I'm getting, but the wire that powers up the rest of the trucks electrical system/fuse box has a fuse in it that keeps blowing? First off, how do you know what size of fuse to put in it? You say it does it mainly when it's raining or snowing, so have you checked your wiper motor? Maybe it's going out and pulling too many amps? Or could be that with the heater blower on, the headlights on, the wipers on, and the radio on it's just too much for what ever fuse you have powering up the fuse box.
