electrical belt squealing problemos

[oldblue1968chevy]

okay..

i have a going alternator bearing, so i decided to take the atlernator off my gmc......it looked newer and i was bored....well turns out it didnt work so i swapped back for my old alterator and while i was doin that, forgot to disconect battery so i shorted something out and caught a wire on fire(went from alternator to starter/starter solenoid) well i replaced that and put everything back they way i thought it went...

well i wake up this am with no power to my ignition switch, so i roll it off goin down into the field, and take off for school, wen i got to school i disconnected the pos. so i can start it this evening after school..

so whats my problemo

oh and wen i push the clutch in and slow down sometimes my belts sqeal like a mofo lol

thanks
