What wires go to the voltage regulator?

Connect the positive battery cable wire — usually red — to the regulator. Connect the wire to the terminal marked “B” (sometimes this terminal is marked “BATT”). Connect the generator or alternator wire to the regulator.

Can you bypass a voltage regulator?

If you have a decent power supply and can control the voltage out of it, AND you know what voltage the regulator you’re bypassing is supposed to product, then yeah, sure – it’s possible.

Does a one wire alternator need a voltage regulator?

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.

Does a voltage regulator have a ground wire?

So the ground is absolutely necessary for voltage regulator to work.

Do all alternators have voltage regulators?

Basically, the voltage regulator controls field current through the rotor, inside the alternator, in order to control alternator output. Without a voltage regulator, an alternator may put out up to 250 volts. The voltage regulator is usually found inside or on the back of the alternator case.

Where does the alternator exciter wire go?

Voltage goes through the light and down the exciter wire to the alternator. The wire is connected to the “L” terminal of the alternator. The exciter wire is used to turn on the voltage regulator.

Does a car voltage regulator need to be grounded?

Other than the possibility of damaging a regulator the answer to the question is no. The case to the voltage regulator is not grounded, it makes zero connection to the case…so it wouldn’t matter. The charging system gets it’s ground from the wire the back of the alternator.

Where are voltage regulators used?

Such a device is widely used in motor vehicles of all types to match the output voltage of the generator to the electrical load and to the charging requirements of the battery. Voltage regulators also are used in electronic equipment in which excessive variations in voltage would be detrimental.

Can you use an external voltage regulator on a 1987 Dodge alternator?

This kit can be used on Standard and High Output Alternators with External Voltage control. Also, this product can be used as a wiring harness and external voltage regulator replacement kit for any 1987 and earlier Chrysler Family vehicle alternator with dual insulated brushes.

When to use an external voltage regulator on a jeep?

For Chrysler and Dodge vehicles after 1987 and Jeep vehicles after 1991. This kit can be used on Standard and High Output Alternators with External Voltage control.

Why is my alternator not working with an external voltage regulator?

Often, especially after installing a high output alternator with external voltage regulator, the alternator voltage control module in the ECU will fail , leaving you with a dead charging system where your external regulator alternator doesn’t work , or doesn’t work the way it should , yet your engine runs fine.

Do you need an external voltage regulator kit?

IMPORANT: IF YOR VEHICLE IS NEWER THAN 2006 YOU MAY ALSO REQUIRE A MODIFIED DRIVER AS WELL AS AN EXTERNAL REGULATOR KIT. MODIFIED DRIVERS SUCH AS PART NUMBERS 150240091MOD, 4622071MOD or 4622081MOD, CALL TO VERIFY IF YOUR VEHICLE IS NEWER THAN 2006

How to make an external voltage regulator to bypass a Dodge?

This can also be done to regulate any 12 volt battery alternator combination. It completely separates the voltage regulating from the computer . Here are the parts I use. A junk yard would also have these parts. Wire Nuts (I solder the connections together but some people use wire nuts.) Loading…
