How to test the stator on a motorcycle?

The orientation of the test leads does not matter in this test. Set your meter to AC Volts and start your motorcycle. Use the choke or have someone help you hold the throttle at around 4000 rpm and check the output between the legs. The output between each pair (A-B, B-C, A-C) should all be equal to each other and above 60 volts AC.

How to check the continuity to ground on a stator?

CHECKING THE STATOR’S CONTINUITY TO GROUND: (most common and easiest test) • With the stator harness connector still unplugged and your multi-meter still in the resistance (Ω) setting, place your red ( +) lead to each of the yellow wires while grounding the black (-) lead to a solid ground.

Can a stator check a DC ignition system?

DC CDI systems use battery power rather than AC power from an exciter coil in the stator so the exciter coil check does not apply for models using DC ignition systems. I’ve never seen official specifications published for checking AC output, so these are numbers that usually work for me.

What should the stator output be at idle?

With the motor at idle you should see around 13 volts or better. At 4000 rpm you should see around 14.5v. As you can see, this motorcycle has a problem with its charging system. The connections between the stator output and the regulator/rectifier input are usually on the left side of these GS motorcycles.

How do you test a stator?

Testing Your Stator So, here is how to test your stator: First, disconnect the stator connector on the left side of the bike. There are three wires. With an AC voltmeter, measure the voltage across each combination of the three wires (pins 1-2, 2-3, and 3-1).

How to check the output?

  • Check the amperes your alternator produces if it operates correctly. Look in your car’s manual and go to the specification section: it’s usually at the back.
  • Wear protective gloves as you need to be in close contact to the car battery to check the ampere output from your alternator.
  • Open the car’s hood and secure it.

    What is a stator on a motorcycle?

    A motorcycle stator is the stationary part of the alternator. The flywheel, or magnet rotor, rotates around the stator to generate sufficient AC power for the motorcycle’s ignition system A motorcycle stator has between four and 18 spokes arranged in a circular fashion.
