15. IGNITION SYSTEM Mongoose/KXR 90/50 IGNITION COIL REMOVAL Remove the spark plug cap. Disconnect the ignition coil wires and remove the ignition coil bolt and ignition coil. Ignition Coil INSPECTION CONTINUITY TEST The CDI unit is not adjustable. If the timing is incorrect, inspect the CDI unit, pulser coil and A.C. generator and replace any faulty parts. Measure the resistance between the ignition coil primary coil terminals. Resistance: Mongoose/KXR 90) : 2.22.6/20°C Mongoose/KXR 50) : 3.715.2/20°C Measure the secondary coil resistances with and without the spark plug cap. Resistances: (Mongoose/KXR 90) (with plug cap) : 8.39K/20°C (without plug cap) : 3.14K/20°C Mongoose/KXR 50) (with plug cap) : 8.81K/20°C (without plug cap) : 3.51K/20°C Correctly operate the tester following the manufacturer`s instructions. Note: The readings in this table are taken with a YF-3501 Tester. 15-7
