SERVICE INFORMATION
GENERAL INSTRUCTIONS (DINK 200i)
Some electrical components may be damaged if terminals or connectors are connected or
disconnected while the ignition switch is "ON" and current is present.
When servicing the ignition system, always follow the steps in the troubleshooting.
The ignition timing cannot be adjusted since the ignition control module is factory preset.
The ignition control module or ECU may be damaged if dropped. Also, if the connector is
disconnected when current is flowing, the excessive voltage may damage the ignition control
module or ECU. Always turn off the ignition switch before servicing.
A faulty ignition system is often related to poor connections. Check those connections before
proceeding.
Make sure the battery is adequately charged. Using the starter motor with a weak battery results
in a slower engine cranking speed as well as no spark at the spark plug.
Use a spark plug of the correct heat range. Using spark plug with an incorrect heat range can
damage the engine.
See chapter 10 for ignition pulse generator removal/installation.
See chapter 14 for ECU removal/installation/inspection.
See section 20 for those components: Ignition switch, Engine stop switch
GENERAL INSTRUCTIONS (DINK 125)
Check the ignition system according to the sequence specified in the Troubleshooting.
The ignition system adopts CDI unit and the ignition timing cannot be adjusted.
If the timing is incorrect, inspect the CDI unit and A.C. generator and replace any faulty parts.
Inspect the CDI unit with a CDI tester
Loose connector and poor wire connection are the main causes of faulty ignition system. Check
each connector before operation.
Use of spark plug with improper heat range is the main cause of poor engine performance.
The inspections in this section are focused on maximum voltage. The inspection of ignition coil
resistance is also described in this chapter.
Inspect the ignition switch according to the continuity table specified in chapter 20.
Inspect the spark plug referring to chapter 3.
Remove the A.C. generator and pulser coil referring to chapter 10.
