ELECTRICAL SYSTEM 6-19
Step 2
1) Measure the battery voltage between input lead wires (O/W and B/W) at the CDI unit with the ignition
switch in the “ON” position.
Is the voltage OK?
Step 3
1) Measure the ignition coil primary peak voltage. (
6-20)
NOTE:
This inspection method is applicable only with the multi-circuit tester and the peak volt adaptor.
Is the peak voltage OK?
Step 4
1) Inspect the spark plug. (
2-8)
Is the spark plug OK?
Step 5
1) Inspect the parking brake switch. (
6-23)
Is the parking brake switch OK?
Step 6
1) Inspect the ignition coil. (
6-21)
Is the ignition coil OK?
Step 7
1) Measure the CKP sensor peak voltage and resistance. (
6-21)
NOTE:
The CKP sensor peak voltage inspection is applicable only with the multi-circuit tester and peak volt adaptor.
Is the peak voltage and resistance OK?
YES Go to Step 3.
NO
• Faulty ignition switch
• Faulty engine stop switch
• Broken wiring harness or poor connection of related circuit couplers
YES Go to Step 4.
NO Go to Step 5.
YES Go to Step 6.
NO Faulty spark plug.
YES Go to Step 6.
NO Faulty parking brake switch.
YES Go to Step 7.
NO
• Poor connection of the ignition coil.
• Faulty ignition coil.
YES
• Faulty CDI unit.
• Poor connection of generator coupler.
• Open or short circuit in wire harness.
