What should the voltage regulator read on a Harley Davidson?
If any of the following tests fail, the voltage regulator needs to be repaired or replaced. Clamp the multimeter positive lead on the AC output wire and the negative lead on the battery charge wire. The multimeter should read .5 volts.
How to test a tractor Dynamo and regulator?
· Start the tractor and run at low speed (about 600 RPM). · Measure the voltage between the power terminal and earth – this is typically 2 or 3 volts but may initially be lower. · Link the field and power terminals with a piece of wire, taking care not to short either terminal to earth. The voltage should rise (possibly to around 8 or 9 volts.)
What does it mean when a voltage regulator reads over 14.5?
If the voltage reads over 14.5, it probably means that you have a faulty regulator. If your voltage reading is below 13.8 volts, you have a weak battery and will need to replace it soon. Read the schematics that came with the voltage regulator.
What to do if your voltage regulator is leaking?
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.

What should the voltage of a voltage regulator be?
Voltage Regulator Test Charging voltage can vary between 13.5 and 14.8 volts, depending on ambient temperature. In a nice, 70 F (21 C) day, you can expect a voltage regulator charging your car’s battery at about 14.2 volts. And the higher the temperature, the lower the charging voltage.
How do you test an alternator voltage regulator?
This test is a simple procedure to check alternator voltage regulator output. You need a digital multimeter for this test. Set the parking brake and shift the transmission to Neutral (manual) or Park (automatic).
What causes a Harley Davidson battery to go bad?
The most common cause of electrical problems on a Harley Davidson is the battery or the voltage regulator. Troubleshooting can be performed in any garage, and it saves on expensive service bills.
What are the symptoms of a bad voltage regulator?
Bad Voltage Regulator Symptom #3: You Notice Engine Problems. A bad voltage regulator can even affect your car’s engine. For example, as this car part stops working properly, you might notice your car’s engine sputters or stalls once in a while. It might also have trouble accelerating as you drive.
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.
