How do you test a Harley Davidson voltage regulator?

How do you test a Harley Davidson voltage 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.

What should a Harley charge at?

Regulation Point: Generally speaking, 14.6 volts is a hard set regulation point on most 12 volt systems such as a Harley.

How do you test a motorcycle charging system?

Disconnect your multimeter for a sec (so voltage spikes don’t nuke it). Now turn the motorcycle on, let it warm up for a bit, and check the voltage at the battery again. At idle, the voltage should be around 12-13V. At 3,000rpm, the voltage should be no more than 15V.

Can a bad voltage regulator drain your battery?

There are many reasons your car’s battery might be dead, and one of them happens to be a broken voltage regulator. This is because when this part burns out, the battery will no longer charge, meaning it will eventually die.

Will a Harley start with a bad stator?

As a result, if your stator is going bad your motorcycle will run very poorly. Eventually, your stator can prevent your motorcycle from starting at all. There are so many different signs pointing towards a failing stator.

Can a Harley run without a battery?

So, can your motorcycle run without a battery? Most modern motorcycles cannot run without a battery. If the battery is at marginal health and some life is still left in it, motorcycle can be started with a push/bump start.

What happens if voltage regulator fails?

A damaged or failed voltage regulator can rapidly diminish the alternator’s ability to cycle power from the battery. This may cause the vehicle to experience dimming or pulsating external systems, such as headlights and dashboard elements.

What should the charging voltage be on a Harley stator?

You can use 13 as a good all around battery voltage. That is a good healthy battery staying charged just above 12 volts. Example only: Let’s say the stator is rated for 10 amps x 13-volt battery: 10 x 13=130 watt charging system. So you have a 130-watt charging system in this example.

Where can I test my Harley Davidson battery?

The battery needs to be a fully charged battery and load-tested to ensure proper readings. If you are not working with a fully charged and functional battery, all other voltage tests will be incorrect. Most places like Auto Zone, Advance Auto, and Pep Boys will charge and test motorcycle batteries for free.

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 is my battery not charging on my Harley Davidson?

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. Often times, a short can happen in the windings around the stator.
