get a multi meter that reads dc voltage & touch the black (negative -) wire to the negative battery post & the red (positive +) wire to the positive battery post with car running. car off is battery voltage, car on is alternator voltage.

Car has very low voltage?
Put a new alternator on it or tear the old alternator apart and replace the voltage regulator in it.
What can cause low voltage in a car?
Alternator going out.
Where is the voltage regulator on 1988 Lincoln town car?
The voltage regulator may be on the alternator.
How do you derive alternating current from car alternator?
The car's alternator is a three phase generating system. Inside the alternator is a three phase full wave diode bridge that changes the AC generated voltage to a DC voltage.
What causes over voltage in a car battery?
A bad voltage regulator in the alternator. Depending on year make and model it may be outside or separate from the alternator.
If a car has a voltage regulator in the alternator does it still work if the cars off?
No, the regulator in the alternator only regulates when the alternator is charging (alternator must be rotating).
Can a car's alternator charge the battery while the car is not running?
No. The alternator has to be turning to produce the charging voltage. It only turns when the engine is running.
Does a voltage regulater make the car run?
No. It controls the output of the alternator.
Where does the voltage regulater go on the 1988 town car?
Inside the alternator
Where is voltage regulator on 2002 Lincoln town car?
It is built into the alternator.
What is the voltage for a car battery whilst car is running?
The voltage for this is 12 volts The alternator/generator should be producing 13.5 to 14.5 volts
Is a diode part of an alternator or the car?
There is a three phase diode bridge in a vehicles alternator. The voltage is generated as three phase AC. The diode bridge converts the AC voltage to DC voltage. This is the DC voltage that is used to charge the battery of the vehicle and run the vehicles electrical systems and equipment.
