alternator upgrade question

Thanks for helping me with this. I already have the blue and the brown soldered together and taped up like I did before the alternator went out. I wish I new exactly what went wrong the first time so it won't happen again. But I have everything wired like I did before except this time I have a 20 amp buzz fuse wired in under the dash on the blue wire. I am going to drive the car today and hope everything goes well. I haven't drove it but cranked it up to see if the alternator was charging. I wanted to ask this question before I fried another alternator (not sure if it was my wiring or the alternator went bad) because I don't want to have to take another alternator back to the parts house.
