How do you change a regulator on a Harley Davidson?
Removal
- Unplug the regulator from the alternator lead; this is beneath the regulator.
- Cut the six cable straps and bend back the two metal tabs securing the regulator wire to the frame member. Remove the battery, battery tray and the seat. Disconnect the regulator wire lead from the main circuit breaker.
Why is the voltage regulator on my Harley 06 not working?
The regulator on my ’06 just went last month, low battery voltage was the cause. The dealership has it now to repair. We’ll see what they come up with. It was the voltage regulator. They said there was a string of defective regulators that they were required to turn in.
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 to do if your battery regulator is leaking voltage?
If the regulator is leaking voltage, the battery will also be leaking voltage. This is a condition that’s easy to test. Using a multimeter, clip the test light on to the negative terminal of your battery. Next, unplug the regulator to get an accurate voltage reading. Using the test light, touch each of the regulator terminals one at a time.
What causes a solid state regulator to fail?
My experience with solid state regulators has been that when they fail they fail, don’t work intermittently, as Jack said you should have the battery and stator tested. The regulator on my ’06 just went last month, low battery voltage was the cause. The dealership has it now to repair. We’ll see what they come up with.

What should I do if my Charger regulator is not working?
Assuming your rectifier part of the unit is still working, you’ll see current flowing to your battery. You will see your battery voltage increasing because it has current flowing into it. If you suspect the regulator part of the unit is not working, you can set your multi-meter to the “DC Volts” setting, generally a 20-volt setting.
What’s the hard set regulation point on a Harley?
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.
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.
