9-26 ELECTRICAL SYSTEM NOTE: Use the special tool, to prevent the rubber of the water proof coupler from damage. • Shift the transmission into neutral and turn ignition switch “ON”. • Crank the engine a few seconds with the starter motor by depressing starter button and check the ignition coil primary peak voltage. • Repeat the above inspection a few times and measure the highest peak voltage. Tester knob indication: voltage () Ignition coil primary peak voltage: 80 V and more  Do not touch the tester probes and spark plugs to pre- vent an electric shock while testing. If the peak voltage is lower than the standard range, check the ignition coil/plug cap as follow. E IGNITION COIL/PLUG CAP RESISTANCE • Check the ignition coil/plug cap for resistance in both primary L and secondary coils. If the resistance is not within the stan- dard range, replace the ignition coil/plug cap with a new one. P 09900-25008: Multi-circuit tester set M Tester knob indication: Resistance (Ω) Ignition coil/plug cap resistance A Primary : 1.1 – 1.9 Ω (+ tap – - tap) S Secondary: 10.8 – 16.2 kΩ (Plug cap – - tap)
