- Set your multimeter to DCV (DC Volts) above 15.
- Make sure your alternator’s positive and negative terminals are clean.
- Put the multimeter’s black cable to the negative terminal and the red cable to the positive terminal.
- Look for an ideal alternator reading of around 12.6.
Is the alternator a generator?
No. An alternator is a device that converts mechanical energy into AC electrical energy. A generator is a mechanical device which converts mechanical energy to either AC or DC electrical energy. An alternator always induces an alternating current.
Why is my alternator overcharging?

- Unusual Sounds.
How do I know if my alternator is charging without a multimeter?
Start the car and rev the engine to 2000 RPM. Observe the ampere or voltage gauge (if your car has one) on the instrument panel. Turn on all of the car’s electrical accessories. A high reading on the gauge while the car is idling indicates that the alternator is charging the battery.
Can you test an alternator without removing it?
If you’re tempted to test an alternator by disconnecting the negative battery cable, don’t do it. A good alternator may indeed keep the engine running without the negative cable, but this was never a good test. In the pre-computer days, you could pull it off without damaging anything.
Is it my battery or alternator?
If your engine won’t turn over or takes far longer than usual, it’s time to grab the jumper cables and attempt a jump-start. If your engine starts and stays running but won’t start again later, it’s likely a battery problem. If your vehicle immediately stalls, it’s probably a bad alternator.
Is an alternator AC or DC?
Car batteries operate on one-way direct current (DC) electricity, while alternators output alternating current (AC) electricity, which occasionally flows in reverse.

What is the purpose of damper winding in alternator?
Damper Winding:
Therefore, damper winding provides starting torque necessary for starting the synchronous motor. It also prevents hunting of synchronous motor, that is it reduces oscillations of the rotor when the motor deviates from synchronism.
Why is my alternator not charging my battery?
The most common reason an alternator is not charging the battery is due to worn carbon brushes or a damaged alternator itself. It can also be caused by a blown fuse or bad wirings. If your serpentine belt snapped off, the alternator will, of course not charge then either.
