Can be a couple of things, the belt may be slipping on the pullys or the brushes are worn in the alternator, possibly the latter, take to a mechanic he won't charge you to look at it. Good luck

Dear Squeaky....
You have a belt that is obviously squealling.This belt is automatically tensioned by one tensioner......have (or take) the alternator off and any autoparts store can have an electrical charging bench test done on the alternator, if that passes then have the tensioner inspected, with that belt squeal i'd be suspect to the tensioner failing, after that spin the rest of your pulluys to make sure they are ot bound up or starting to seize up, get back to me if ya have any other questions, I'M HERE TO HELP!!!!

Alternator won't charge although alternator repair shop said it is ok


First did you clean the battery terminals and posts on your battery and how old is the battery and did it pass the load test ? Is your alternator belt squealing while everything turned on? If so it needs to be tightened , After doing all this Put a volt meter on the battery terminals while the car or truck is running , It should read between 13.5 V and 14.5 V and if so check with every thing turned on and if the voltage drops below 13.5v and If so the Alternator is bad

Battery lite on,charge gauge dropped below half


Hi, If the belt is good then a visual inspection of the wiring at the back of the alternator is first, give it a wiggle and make sure its sound. If you have a multi meter and you can check battery voltage at the alternator then make sure you have good battery voltage at the main positive terminal at the rear of the alternator(should be the biggest red wire) and then if you can safely check the voltage engine running to eliminate a fault further up. If you have good voltage stood and it doesent change when engine is running then alternator is probably dead.

How to tell if alternator is gone on 2000 protege


Hi John, The easiest way to check the alternator is to connect a voltage test meter between the positive and negative battery terminals. A fully charged battery should give 12 and a half to twelve and three quarter volts. Have some one start the engine (making sure the vehicle is in neutral or park and with the park brake fully applied). Voltage during start should not drop to lower than eleven volts. With engine running the voltage reading should be around thirteen volts. Turn on the head lights (full beam) and the heated rear window. The voltage should be maintained or increase slightly above the previous reading. If during start up the battery voltage dropped below that stated earlier the battery will probably need replacement. If the voltages remain constant or drop during the engine run, and if voltage drops below pre start conditions, the alternator requires attention. Regards John

Replaced alternator and battery still showing low/varying voltage


check the battery ground cable and make sure that you have a good engine ground.to do this you need to use a voltmeter and check for voltage drop between the battery terminal and engine it should not be more 0.4 volts .if that is o.k. the alternator internal voltage regulator is not good and replce the alternator again.also make sure the drive belt is tight.
