Default Alternator fuse keeps blowing

Ok so this one is really getting me. I recently replaced the battery and alternator and everything was all good for like 2 weeks and now out of nowhere my alternator fuse just keeps blowing. I have checked and rechecked all wires at the battery and alternator and in between the 2 and nothing. Ill put a new fuse in and then it charges at idle but after about 1800 rpm the fuse blows every freakin time.

Is it the right alternator? Where did you buy it from?

Also, are all the contact nice and clean free of grease... you might have a bad wire too.

I'd have the alternator tested. You could have possibly gotten a bad one that has an internal short. Had practically the same issue on another vehicle one time and it turned out to be the alternator itself.

It's from orielys. Connections are all clean. I've replaced the power wire as it was very corroded. It's such a pain to get the alt out of there. Couldn't I just test the amperage right off the alt while it's running?
