Ignition Troubleshooting (Engines With Black Stator)
STEP 3 – Stator Low Speed and High Speed Test
Stator Low Speed Test
DCV ACV
DVA
1. Use Multimeter / DVA Tester 91-99750.
2. Crank engine and observe meter reading.
IGNITION VOLTAGE – 9 AMP STATOR
Tested Part
Stator Low Speed

TEST RESULTS
If voltage output is low to either the stator low
speed or stator high speed, the stator or switch
box is defective. Go to stator test and test stator.
If stator tests OK, replace switch box and repeat
step.
If voltage output is good to either the stator low
speed or stator high speed, replace the switch
box and repeat step
