"Synch Pulse" (Stator)

Using an analog voltmeter, insert positive probe into Blue wire at distributor connector. Insert negative probe into Gray wire with tracer at distributor connector.
NOTE: Do not remove connector from distributor. Insert voltmeter leads from rear of connector. Do not puncture wire.
With voltmeter set on "15-Volt A/C" scale, turn ignition on. Voltmeter should indicate 5 volts. If voltage is indicated, go to step 4). If no voltage is indicated, check voltmeter leads for good connection and go to next step.
If there is still no voltage reading, turn ignition off and remove ECU. Reconnect harness and turn ignition off and remove ECU. Reconnect harness and turn ignition on. Check for voltage between ECU pin "C-16" and good ground. If voltage still does not register, test system with System Tester (M.S. 1700).
If 5 volts was detected, check for continuity at the following points:
- Between Blue wire at distributor connector and terminal "C -16" at ECU.
- Between Gray wire with tracer at distributor connector and terminal "C-5" at ECU.
- Between Black wire at distributor connector and good ground.
If no continuity is shown, repair wiring harness. If continuity is shown, reconnect voltmeter as in step 2).
While observing voltmeter, crank engine. Voltmeter needle should fluctuate back and forth during engine cranking. This verifies proper operation of distributor stator. If voltmeter needle does not fluctuate, replace stator.
