7) Inspection of Ignition Coils
This test can be made without removing parts.
1. Remove ignition coil coupler.
2. Measure ignition coil resistance. Replace if other than
specified value.
Ignition Coil Resistance :
Primary Side : Between a and b 0.45 - 0.55 Ω
Secondary Side : Between c and d 10.8 - 16.2 kΩ
3. Install plug cap onto high tension cord by twisting
clockwise.
4. Connect plug cap to spark plug.
8) Inspection of Pick Up Coil
(Crank Position Sensor)
2. Disconnect pick up coil 1 connector.
3. Measure resistance between terminals.
Replace pick up coil if the resistance is out of specified
range.
Resistance between Terminals : @20˚C (68 ˚F)
451 - 611 Ω
9) Inspection of Pick Up Coil Air Gap
1. Measure air gap a between pick up coil 1 and flywheel
2.
Adjust air gap if out of specified range.
Air Gap a :
0.5 - 0.9 mm (0.020 - 0.035 in)
