You have a short somewhere. Since both generator and alternator are positive ground should not be a polarity issue. If the alternator is a negative ground and battery is hooked positive ground that could cause the problem you are seeing. Put the generator back in and hook up. If fuse does not blow and when you connect the alternator it does, then the alternator has the wrong polarity.
