How do you wire a voltage regulator to an alternator?

How to Wire an Alternator Voltage Regulator

1. Open the hood of your car.
2. Remove the black battery cable from the car’s battery terminal using a wrench.
3. Locate the voltage regulator.
4. Find the multi-wired harness nearby the alternator and voltage regulator.
5. Insert the plug into the socket on the voltage regulator.

What is the difference between 1 wire and 3 wire alternator?

“The 1-wire alternator only has a sense of what it is sending current to, which is the battery. The three wire alternator senses voltage at the fuse block and the ignition, and the alternator will then charge more to get all the systems up to power,” Overholser sums up.

Do you need a voltage regulator with a one wire alternator?

YES, especially when using a one-wire alternator. Changing the pulley ratio of the alternator by slowing it down will generally keep the one wire regulator from cutting on . This may also produce a low voltage problem at engine idle speed, depending on the amount of reduction.

What does the alternator exciter wire do?

The exciter wire is used to turn on the voltage regulator. This wire, when unplugged, should have approx. 12.5 volts with the key on. If it does not then the alternator will not work.

Does alternator need excitation?

Without the excitation system the AC alternator would have no way of building its voltage as it starts to rotate, nor would not be able to regulate its voltage to the pre-set nominal level while running at its rated speed. So, without an excitation system, an AC alternator would be useless for its purpose.

Why DC is used for excitation?

Originally Answered: Why dc is used as excitation of alternator? Its because you need a constant field. If you give ac it produces a time varying field. In a constant field the armature cuts the flux, hence a time varying emf is induced.

Will an alternator charge at idle?

Yes, the alternator does charge the battery while the car is idling – regardless of the load on the battery. However, if your electrical use load (radio, lights, fan, etc) exceeds the amount of charge the battery is receiving from the alternator, you will end up with a discharged battery at some point.

How long does it take for an alternator to charge a battery at idle?

Basically, at idle you can probably get 80 amps out of your alternator. You can charge a flat battery to 80 percent full in about 2 hours, so long as you alternator can manage produce around 14 volts at the battery terminals this whole time.
