I just hooked up a powermaster alt. 60/100amp. I have it wired direct to the battery master disconnect. Is this right?

I have ran the original 37 amp alt. for 2 years with no problems with blowing fuses. I have dual electric fans from some unknown car, they work great. I have the wired with a relay and a 30amp fuse on the ground wire. What would cause this fuse to blow?? No shorts in the wire, I traced them and all looks good. Are the fans just getting worn out?? I am trying to tune in the timing on my motor, could being too far advanced put a strain on the electrical system?? I have an old MSD-7a with fixed curve timing computer, MSD billet locked out dist. I am also running a holley blue pump. any help is greatly appreciated.

Thanks,

Travis
