9) Inspection of Ignition Coils
1. Remove ignition coil coupler.
2. Measure ignition coil resistance. Replace if other than
specified value.
3. Install plug cap onto high tension cord by twisting
clockwise.
4. Connect plug cap to spark plug.
10) 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.
11) 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.
This test can be made without removing parts.
Ignition Coil Resistance :
Primary Side : Between a and b 0.4 - 0.6
Ω
Secondary Side : Between c and d 10.8 - 16.2 k
Ω
(6.8 - 10.2 k
Ω
without plug cap)
Resistance between Terminals : @20˚C (68 ˚F)
425 - 637
Ω
Air Gap a :
0.7 - 1.0 mm (0.028 - 0.039 in)
