Where is the voltage regulator located?
On most vehicles, the voltage regulator is either located inside of the alternator or mounted to it. But vintage vehicles often have an external voltage regulator, which may be mounted to the fender well, firewall, etc. It's also important to note that some modern vehicles do not have a voltage regulator at all.

Does a golf cart have an alternator?
Unlike with a regular car battery that charges as it's running, a golf cart does not have an alternator in which to do this. It should be a 3-phase charger and pay close attention to the position of the battery poles while charging.

How many volts should a starter generator output?
It should peak at about 15 volts (the maximum output of the Starter/Generator’s charge ability). If it does increase, then the Starter/Generator is alright. If it doesn’t, there is a problem with the Starter/Generator.
How to test a starter generator?
In order to test the function of the Starter/Generator and the Voltage Regulator, the wire attached to DF can be removed and while a meter is used to monitor the voltage B+, DF can be shorted to ground (with a jumper) with the motor running. Before the jumper is shorted to ground, the voltage at B+ should, of course, reflect the charge state of the battery (around 12 volts), but when the jumper is touched to ground (which is what the Voltage Regulator does in instantaneous bursts), the voltage at B+ should rise as the motor’s speed is increased. It should peak at about 15 volts (the maximum output of the Starter/Generator’s charge ability). If it does increase, then the Starter/Generator is alright. If it doesn’t, there is a problem with the Starter/Generator. If the voltage does increase, but the voltage at B+ doesn’t increase when the wire is re-attached to DF as the speed of the motor is increased, the Voltage Regulator is the culprit.
What happens when a starter generator spins?
That completes the circuit, so the Starter/Generator begins to spin. As it spins, a voltage appears at the DF terminal of the Starter/Generator, which is connected to the Voltage Regulator.
How many volts should a jumper have before it is shorted?
Before the jumper is shorted to ground, the voltage at B+ should, of course, reflect the charge state of the battery (around 12 volts), but when the jumper is touched to ground (which is what the Voltage Regulator does in instantaneous bursts), the voltage at B+ should rise as the motor’s speed is increased.
What to do if your golf cart is not charging?

A faulty voltage regulator can lead to many problems, including an overcharge which can burn out numerous electrical components or having a golf cart battery that will not hold a charge at all.
How to read voltage on a car?
It's time to use your voltage meter. Connect the meter to the battery poles and then start your engine whilst being careful not to spin. You want the voltage to read over 12.6. Now slowly increase your engine speed. You should find that your voltage increases until you hit around a thousand revolutions per minute (RPM). From that point, the reading will stay in one place. This should be 13. volts, though it is fine if it remains in the spectrum of .5 volts higher or lower than this.
