17. IGNITION SYSTEM People GT 125i Ignition Coil SPARK PLUG For spark plug inspection and adjustment, refer to page 3-5. IGNITION COIL INSPECTION Remove the seat and met-in box. ( 2-6) Remove the ignition coil. Primary Coil IGNITION COIL CONTINUITY TEST Inspect the continuity of the ignition coil, primary coil and secondary coil. This is a general test. Accurate ignition coil test must be performed with an ignition unit tester. Secondary Coil with plug cap Measure the ignition coil resistances at 20. Primary coil 3.57~4.83 Secondary coil with plug cap 15 ~ 19 K Secondary coil without plug cap 10 ~14 K Secondary Coil without plug cap 17-3
