ELECTRICAL SYSTEM 15 19 Ignition Coil Installation Notes NOTE Connect the primary leads to the primary coil termi nals as follows Black and red leads No 1 ignition coil Green and red leads No 2 ignition coil The and Q markings next to the primary coil terminals on the ignition coil body indicate the polarity of the terminals The polarity of the two spark plug leads are shown when the primary leads are con nected as indicated in the figure OSince a tester other than the Kawasaki Electrotester may produce a different arcing distance the Kawasaki Eiectrotester is recommended for reliable results Remove the ignition coil Connect the ignition coil with the spark plug cap left installed at each of the spark plug lead to the tester and measure the arcing distance Ignition Coil Test Secondary Lead Connect G or BK Lead few Connect R Leads Pickup Coil inspection Disconnect the pickup coil connector Zero the hand tester special tool 57001 983 and connect it to pickup coil leads lf there is more resistance than the specified value the coil has an open lead and must be replaced Much less than this resistance means the coil is shorted and must be replaced Pickup Coil Resistance 100 150 LI Using the highest resistance range of the hand tester measure the resistance between the pickup coil leads and chassis ground Any meter reading less than infinity indicates a short necessitating replacement of the pickup coil assembly 1 Electo tester 2 Voltage Source 3 Igniton Coil WARNING oTo avoid extremely high voltage shock do not touch the coil or lead If the distance reading is less than the specified value the ignition coil or spark plug cap is defective Ignition Coil Arcing Distance 7 mm or more To determine which part is defective measure the arcing distance again with the spark plug cap removed from the ignition coil If the arcing distance is subnormal as before the trouble is with the ignition coil itself If the arcing distance is now normal the trouble is with the spark plug cap Ignition Coil Inspection Measuring arcing distance The most accurate test for determining the condition of the ignition coil is made by measuring arcing distance with a coil tester special tool 57001 1242 Measuring coil resistance If the arcing tester is not available the coil can be checked for a broken or badly shorted winding with an
