If the checks reveal the values to be correct and the problem persists, the magneto wiring
must be checked. If this is correct, the CDI coil should be renewed.
Important precautions:
• Never connect or disconnect cables or connections with the ignition on or the engine
running.
• Never carry out electric welding or cause sparks with the CDI connected.
IGNITION SYSTEM
Checking the HT coil:
Before starting the checks, ensure that the CDI HT coil is properly earthed, that it is not
corroded or dirty where it is secured.
If the checks reveal the magneto values and the wiring to be correct, the CDI coil should
be renewed.
Before renewing the CDI coil, check that the connections and the wiring are in good con-
dition.
CHECKING THE SPARK PLUG SUPPRESSOR CONNECTOR
Remove the connector from the spark plug by turning the connector in an anti-
clockwise direction.
Check that the copper wires protrude from the HT cable.
Resistance: 5KΩ +/- 20% a 20º C
