How do you test a Harley Davidson regulator?

Posted on by Arif Clayton

How do you test a Harley Davidson regulator?

To check the regulator unplug it from the stator. Take a test light and clip it to the negative terminal of the battery and then touch first one pin and then the other on the plug that goes to the regulator. If you get even the slightest amount of light from the test light the regulator is toast.

How do you change the voltage regulator on a Harley Davidson?

This specific video shows you how to change your Harley voltage regulator, also known as the voltage regulator rectifier. We remove the old regulator and the wire off the 30 amp breaker and install a new voltage regulator and wire it correctly. We then insert the plug into the Stator allocation.

What should the voltage be on a Harley Davidson battery?

Turn the ignition and start the bike. The volts should not drop below 9.6 volts when the starter engages. Turn the throttle to rev the engine. As the engine is revved, the volts should go up to 13 or 14 volts. Identify the wires. The battery charge lead runs form the voltage regulator to the positive side of the battery.

Where does the charge lead go on a Harley Davidson?

The battery charge lead runs form the voltage regulator to the positive side of the battery. The AC output lead wire leads from the voltage regulator to the stator.

Why does my Harley Davidson have a voltage drop?

’88 Softtail (FXSTC). Your right NewHD, he may have a ton of current draw with that kind of voltage drop. Something sure is not right. Either a bad battery or too much current draw due to possible engine drag.

What does the regulator on a Harley stator do?

The regulator protects the battery voltage and when the battery voltage climbs too high it shuts off current to ground and bleeds it off as heat. That is what the heat fins on the regulator box are for, to dissipate the heat.

What should the voltage be on a Harley Davidson Charger?

Generally speaking, 14.6 volts is a hard set regulation point on most 12 volt systems such as a Harley. Basically, this does not allow the regulator to send voltage to the battery any higher than 14.6 volts. If the stator fails, your battery will no longer be charging when you’re riding your motorcycle.

Where are the stator wires on a Harley Davidson?

If you have a short to ground then you have no output from the stator. Find where your 3 stator wires are. On a Harley, this is up front near where the inner primary connects to the motor case. Right by the seam. The three wires will track straight from there to your regulator/rectifier.

How to test the battery and voltage regulator on a Harley?

Step 1. Check the voltage of the battery while it is disconnected from the bike using the multimeter. The volts should be no less than 12 volts.

Can a stator be replaced on a twin cam Harley Davidson?

In this video, Mike walks us through the process of a full charging system test, along with the removal of a complete charging system on a Twin Cam touring model. He demonstrates the stator replacement with a 50 amp upgrade. This upgrade will keep your battery up to snuff as the demands on the battery and charging system keep growing.
