HARNESS INSPECTION PROCEDURE

USING OSCILLOSCOPE





1. Primary signal of ignition coil
- Run the engine at an idle revolution speed.
- Connect the probe to oscilloscope pick-up point 1 as shown in the circuit diagram, and check the primary signal of the ignition coil.





2. Control signal of ignition power transistor
- Connect the probe to oscilloscope pick up point 2 as shown in the circuit diagram, and check the control signal of the ignition power transistor.
