Toyota gt four alternator wont charge battery?
Check fuses first. If fuses are good, check the voltage from the negative battery cable to where the wire bolts onto the back of the alternator. (With the engine running). If you can't reach the back of the alternator, then measure across the posts of the battery. Voltage should be about 14 volts DC. If lower than that, replace the alternator. When you replace an alternator, it's a good idea to replace the battery, as a precaution.
Your car has gone dead 3 times in the last two weeks but it will start with a boost What is wrong with it?
Three things to look for: (1) A loose belt will not spin the alternator fast enough to fully recharge the battery - tighten and/or replace the belt; (2) A bad or weak alternator will either not provide enough charge, or any charge at all to the battery - have the alternator checked out and replace if necessary; (3) a battery with a dead cell will not hold a charge and will "die" quickly - have the battery checked out and replace if necessary.

Why won't my battery keep a charge?
When a battery reaches the point where it will not hold a charge, either your alternator is bad, or (much more likely) the battery has reached the end of it's useful life. The only solution is a new battery. Any retailer who will replace your battery while you wait will also be able to check your alternator.
How can I test my alternator to see if it is discharging my battery?
You can have the alternator tested free of charge at just about any major auto parts store. By the way, a bad alternator will not "discharge" a battery - the alternator's function is to provide the charge to the battery. If the alternator is faulty, then it is not providing the charge necessary to keep other components from discharging the battery. I had the alternator tested and it was charging. If the alternator has a bad diode, it will discharge the battery. I replaced the alternator and everything is fine.
