and then connect the test harness (3
pins) a.
2. Measure the lighting coil output peak
voltage between all combinations of the
terminals. Replace the lighting coil if
below specification.
3. Measure the lighting coil resistance.
4. Disconnect the test harness a, and then
connect the lighting coil coupler a.
