IGNITION SYSTEMIGNITION COIL INSPECTION● Remove the luggage box● Remove the primary wire.NOTE•Since the resistance value of primary coil isinherently very small, it is difficult to distinguish itfrom a shorted wire.● Measure the peak voltage of the ignition coil primaryside first.● If the resistance value is withtin the specified rangethe coil is good.● It resistance (infinite), replace the coil with a newoneSTANDARD VALUE: 0.1~0.5SPARK PLUG CAP● Remove spark plug cap from plug.● On condition that there is plug cap, measure theresistance between plug cap and the primaryterminal.● If the resistance shows (open wire), pull out plugcap and measure the secondary resistance.STANDARD VALUE : 6.5~9.8 ● Measure resistance between the primary coil terminaland high-tension cord.● If the resistance is (open wire), replace the coilwith a new one.STANDARD VALUE : 2.7~3.5 ● Check the primpary voltage of ignition coil.● On condition that iginition cord is connected,connect the peak voltage adaptor(+) cord to greenterminal, and (-) cord to black terminal. Then startvehicle and check.STANDARD VALUE : 100~250VIGNITION COILREPLACEMENT● Remove the high-tension cord from the plug,remove the plug cap.● Remove the wire from the ignition coil.● Remove the primary wire from the ignition coil.● Loosen the ignition coil fixing bolt securing theframe, remove the ignition coil.● Install in the reverse order of removal.
