Coil windings resistance inspection
Disconnect the connector (1) from the coil (2).
- Remove the coil (2) as described in the relevant paragraph.
- Measure primary and secondary winding resistance with a meter.
- Primary winding resistance: 0.6÷0.7 ±15% at 20°C.
- Secondary winding resistance: Open circuit.
If resistance is outside the specied limits, replace the coil.
- Terminal cap resistance: 4.5-5.5 K ±5% at 20°C.
If resistance is outside the specied limits, replace the cap.
Electronic control unit (ECU)
Remove the saddle (see Section "E") to gain access to the electronic control
unit (1).
It is composed of a capacitor, a rectier circuit that handles input signals re-
ceived from the pick-up sensor, a circuit that controls ignition timing advance
in accordance with pick-up sensor inputs and a switching circuit for capacitor
discharge.
