Troubleshooting Stator 173-1235

  This information was packed with stator number 173-1235.  It is not for every stator. Some  tips are some good ones that the customer can use to help trouble shoot other stators as well.   The wiring codes could be different on other stators. These products were designed to be installed by a professional marine mechanic.

No fire at all:

1. Disconnect the kill wire and retest.  If the ignition now has fire, check the kill circuit.

2.. Check the resistance between the brown and brown/yellow wires.  You should read approximately 450-600 ohms.DVA (peak voltage) should be 150v or more.

3. There should be no connection from any of the winding leads to the metal body (core) of the stator.

4. Inspect the flywheel outer trigger magnets to see if they are loose or broken.

5. Disconnect the rectifier/regulator and retest.  If the fire returns, replace the rectifier/regulator.

No fire in one cylinder:

1. Swap the brown wire and the brown/yellow wire and see if the problem moves. If it does, the stator is likely bad.

2. Check the power pack and the trigger

High speed miss or weak hole shot:

1. Connect a DVA meter between the brown and brown yellow wires and do a running test. At no time should the voltage exceed 400v. If it does, the regulator circuit in the power pack is bad.  The voltage should show a smooth climb and stabilize, gradually falling off at high RPM (above 5000). If you see a sudden drop in voltage right before the miss becomes apparent, the problem is likely in the stator.

2: Disconnect the rectifier and retest.  If the problem disappears, replace the rectifier and retest to verify that the problem was the rectifier.
