How to Test a Stator
How to Know if a Stator is Defective
To know without a doubt if your stator is defective, there are 3 simple tests you can do.
You will need a multimeter set to Ohms for this test. Test every lead of the stator’s connector and note the readings. The reading of each combination should be the same (test leads 1-2, 2-3, and 3-1). If they are different, your stator is defective.
Set your multimeter to Ohms. Put the negative lead on the engine’s ground and the positive lead on each wires of the stator’s connector one by one. You shouldn’t get a reading at all. If you get a reading, even very small, on any wire, the stator is defective and must be changed.
AC Output Test
Put your multimeter to AC Volts and start you vehicle. As with the Ohms test, test between each lead of the connector (1-2, 2-3, 3-1) and note the readings. They should all be the same (E.g. 20v/20v/20v). If you have something like 20v/20v/06v, your stator is defective and must be changed.
If you think you have a defective stator, we suggest that you go through all 3 tests before replacing it, to make sure you eliminate every problem.
