When alternator went out, it could have taken out a fuse if the alternator shorted. The main battery cable to the alternator is not fused, but in your panel you should find an ALT fuse. most alternators have two to three small wires that are in a pigtail that plug into the alternator. these small wires are fused. if your car can't pass current through an open fuse. then there is nothing to essentially tell the alternator to turn on. another thing to check, is whether the battery light comes on. if you turn the key to the forward position, without trying to strart the engine, your prestart lights should all light up. this is a system precheck before the engine starts. the battery light should come on at this point. if the light doesn't come on that is an indication of a fuse being blown. in a lot of vehicles, from the seventies to the late nineties, the charge light, or battery light has to work in order for the alternator to work. if the bulb in the dash(which is behind the battery light) burns out, your alternator will not receive power to turn on and work. again, newer vehicles do not have a light circuit that it relies on for the alternator to function. keep in mind, your battery light should have come on and been on the entire time the old alternator was in the vehicle. if it wasn't on, then this is something to pursue further.

How do you run car to charge up new battery?

New batteries almost always come fully charged. If it was not then charge it with a battery charger and do not use your vehicle alternator to charge a dead battery. You may do harm to the alternator which is not built to charge a dead battery but is instead built to keep a good battery fully charged.


Will battery recharge after bad alernator is replaced?

An alternator is designed to keep a fully charged battery at peak level. It is not designed to charge a dead battery. Installing a new alternator on a car with a dead battery can in some cases ruin the new alternator. Fully charge the dead battery before starting the engine.


Can a faulty alternator drain a new battery?

It can, though it is unlikely -- the alternator and the voltage regulator would both have to be faulty. A faulty alternator will not charge a battery, though, so it may seem normal until the charge put into the battery at the store runs out.


Why new battery and alternator won't hold a charge when car is running?

The alternator does not hold a charge. It charges the battery. If it will not charge the battery then either the alternator is defective, battery is defective, or the connections are corroded or loose. You should read 13.5 to 15.5 volts at the battery with the engine idling. Check it with a DC volt meter. If you get less the alternator is defective. If you get much more the voltage regulator is defective.
