IGNITION
DESCRIPTION OF THE SYSTEM
System logic
- The fundamental parameter is the rpm reading from the
pick-up
- Based on the information from this sensor the ECU calcula
tes the moment in which the spark plug should fire.
Components
- Engine rpm sensor (pick-up)
Sensor resistance: 105 -124 _ at 20º C
(magneto side connector between R and B cable).
- Ignition coil
