Repair manual KTM 85 SX Art No 3.206.008-E
Resistor values of the ignition system - Stator
– Unplug the connector on the ignition stator and measure the
resistance of the stator coils at 20° C using a digital multimeter.
Pulse generator: between the white/red and white/blue cable
Multimeter display: 310 Ω +/- 60 Ω
CDI voltage supply: between the green/blue and black cable
Multimeter display: 55 Ω +/- 10 Ω
Capacitor charging coil: between the black/red and green/white cable
Multimeter display: 900 Ω +/- 180 Ω
NOTE: the stator does not need to be removed to measure.
Ignition coil
– Unscrew the spark plug connector and disconnect the cable for the
primary drive.
– Measure the resistance on the primary side of the ignition coil
between the primary drive plug and the ignition coil ground.
Multimeter display: under 10 Ω at 20º C
– Measure the resistance on the secondary side of the ignition coil
between the high voltage cable and the ignition coil ground.
Multimeter display: 7900 Ω +/- 1500 Ω at 20º C
NOTE: The ignition coils do not need to be removed to measure.
