electrical belt squealing problemos

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

At first I thought you had fried a fusible link, but if you were able to bump start the truck then you had power to the fuse panel and to the key switch. The ignition comes off the key switch as does the starter solenoid power wire (purple). Did you mean that you weren't able to start the truck with the key switch? If not then either you have no power to the solenoid via the purple wire or you have fried the solenoid or worse the starter.
Try jumping the starter solenoid with a screwdriver, short the battery cable post to the S terminal on the solenoid where the purple wire should be connected. Make sure the truck is out of gear and the wheels are blocked!!!!!!!!. If the starter turns then the problem is in the purple wire from the key switch. If it doesn't then the solenoid is bad. IF you hear a loud click then the solenoid is probably good and the starter is bad.
Here's a pic to help.

Re: electrical belt squealing problemos

If the belt is tight then the squeal is most likely from the bad alternator bearing you mentioned. Mine used to do the same thing. Sometimes if I turned it off and restarted it the squeal went away but not always. As for no power at the ig switch, I second VetteVet.

We can deal with that when we get his starter working. It may not even be a belt squeal,sounds to me like the throw out bearing and it could be the old alternator and or a waterpump bearing. belt squeal usually happens when accelerating not letting off. It's a good chance the belts are loose since he just changed the alternators.

Re: electrical belt squealing problemos

Bad battery. Your battery shorted a cell or two when you short circuited the wiring. Now the alternator is putting out way too much current trying to charge the dead battery which in turn makes the belt slip. If it was a fuel injected vehicle it probably would not run at all. What is the battery voltage with and without the engine running?

Re: electrical belt squealing problemos

okay...right now the key is off, batt. is hooked up, it will most likely not start tom. am when i wake up, so i'll roll it off down the driveway...and when i get to school i undo the + (look like i having engine problems, so embarrasing but idc) and get outta school, go crank it the voltage meter reads 7-8 and it barely starts (but its always done that, thats nother problem in itself lol)

okay, that pic up there, ive gotta wire going from the BIG nut going to a lil bolt sticking out of the alternator..thats how it was, would not suprize me if thats wrong, po tried to 'rewire' everything lol

i think the starters good. might be the batt...whats a good way to check the batt. ive gotta atv batt. tester lol and might go put it on the trickle charge overnite and check the wtaer level right now...brb thanks!
