Question

85 monte carlo ls 4.3 2 new alternators put on the alternator charges when tested off the car but doesnt charge the battery also this is the 4th belt put on it (v-belt system) the belt squeals even when its tight or loose PLEASE SOMEBODY HELP ME BEFORE I DRIVE IT OF A CLIF

Answer 1

How do you know it isnt charging? are you basing that off a continual dead battery. Probably one of your accessories is pulling all the power-either when the car is on or more likely off

Answer 2

Check for a lightbulb that doesn't shut off (trunk, underhood, glovebox) cigarette lighter not popped out, something in your sound system wired direct so it doesn't shut off....

Belt squeels because you have wrong size pully on alt.or it's misaligned, or if you have serpentine belt idler pulley is bad....

Answer 3

Wrong belt if it will not tighten up. See if the bulb in the dash is working as this is the turn on "switch" for the alternator. bulb should be on if switch on eng. off

Answer 4

When you have it running....take it to Auto-Zone...they will check it free while it's on the car to see if it's charging. Squealing could be idler pulley or any one of the other things the belt goes around. Make sure you have the belt going around the right things.......if not you could have the alternator turning backwards...and that will NOT charge.
