15 20 ELECTRICAL SYSTEM ohmmeter However an ohmmeter cannot detect layer shorts and shorts resulting form insulation breakdown under high voltage Disconnect the primary leads from the coil terminals Measure the primary winding resistance oConnect an ohmmeter between the coil terminals CSet the meter to the x 1 2 range and read the meter Measure the secondary winding resistance oPull the spark plug cap off the lead Connect an ohmmeter between the spark plug lead and the terminal oSet the meter to the x 1 ki2 range and read the meter If the meter does not read as specified replace the coil If the spark plug electrodes are corroded or damaged or if the insulator is cracked replace the plug Use the standard plug or its equivalent Spark Plug Gap Measure the gap with a wire type thickness gauge If the gap is incorrect carefully bend the side electrode with a suitable tool to obtain the correct gap Spark Plug Gap 0 6 0 7 mm Spark Plug Gap Ignition Coil Winding Resistance Primary windings Secondary windings 2 1 32 S2 10 16 kQ Ignition Coil Winding Resistance 1 Insulator 2 Center Electrode 3 Plug Gap 4 Side Electrode IC Igniter Removal I Measure primary winding resistance 2 Measure secondary winding resistance 3 Ignition coil lf the meter reads as specified the ignition coil windings are probably good However if the ignition system still does not perform as it should after all other components have been checked test replace the coil with one known to be good Check the spark plug leads for visible damage If any spark plug lead is damaged replace the coil Remove the left side cover see Frame chapter in this text Pull the igniter outward evenly as far as it will go Pull the igniter upper side out of the rear fender tongue just enough to clear the tongue then pull the lower side out CAUTION Pulling either side of the igniter too far out may break the fender tongue and the rear fender will need to be replaced Spark Plug Cleaning Inspection Remove the spark plug Clean the spark plug preferably in a sandblasting device and then clean off any abrasive particles The plug may also be cleaned using a high flash point solvent and a wire brush or other suitable tool If the spark plug electrodes are corroded or damaged or if the insulator is cracked replace the plug Use the standard plug or its equivalent A Igniter B Rear Fender Tongues Pull off the connector and remove the igniter
