10.5 - IGNITION SYSTEM
DESCRIPTION OF THE SYSTEM
Logic of the system
- The fundamental parameter is the rpm reading from the engine revs sensor (pick-up)
- Based on the information from this sensor, the CDI unit calculates the moment in which the spark plug should
fire (ignition advance).
Components
- Engine RPM sensor (pick-up)
- Ignition coil
- Ignition unit (CDI unit)
- Main relay
Description of components
- Engine RPM sensor (pick-up)
Sensor resistance: 105-124 a 20º C
(magneto side connector between R and BR cable).
CHECK THE INSULATION TO
EARTH OF THE REV SENSOR
(PICK-UP).
- Ignition coil
Resistance of primary coil: between the two terminals
0,21 +/- 0,025 a 25+/-5º C
Resistance of secondary coil between the end of the spark plug cable and the primary connector (where
the Y/GR cable is connected).
3,1 K +/- 0,31 K a 25 +/-5º C
Primary coil
Secondary coil
Spark plug connector cap
resistance 5K at 20°C
Red cable (R)
Brown cable (BR)
