6.1 Preparation data
Matters needing attention in operation
1. Inspect the ignition system in accordance with the order stipulated in the fault diagnosis table.
2. The ignition system is an electronic auto-advance device integrated in the CDI group, therefore the ignition
time needs no adjustment.
3. Inspect the ignition system in accordance with the order stipulated in the fault diagnosis table.
4.Take particular care in disassembly that the CDI group of ignition system should not fall off and drop down
or should not stricken with might（which is the main cause of fault）
5. Bad socket contact is the main cause of the ignition system fault, so inspect whether the joint of each part is
in poor contact or not.
6. Inspect whether the spark plug is utilized at a proper thermal value. Improper spark plug may lead to
unsmooth operation of engine or burn-out of the spark plug.
7. Inspection in the chapter is based on explanation of peak voltage and the judgment whether the resistance
value of ignition coil is OK or not according to records after the inspection.
8. Inspection of the main switch should be performed in accordance with the conduction table.
9. The disassembly of the alternator and stator should be conducted in accordance with the disassembly
explanation.
