62Y3A11 8-1612345678IChecking the pulser coil1. Measure the pulser coil output peak volt-age. Replace the pulser coil if belowspecification.WARNINGWhen checking the peak voltage do nottouch any of the connections of the digitaltester leads.NOTE:• Use the peak voltage adaptor with the digi-tal circuit tester.• When measuring the peak voltage, set theselector on the digital circuit tester to theDC voltage mode.Checking the pulser coil air gap1. Turn the flywheel clockwise to align theprojection of the flywheel with the pulsercoil projection.2. Measure the gap between both projec-tions with a thickness gauge 1. Adjust ifout of specification.Digital multimeter: YU-34899-ADigital circuit tester: 90890-03174Peak voltage adaptor:YU-39991 / 90890-03172Test harness (2 pins):YB-06767 / 90890-06767Charge coil output peak voltage:Brown (Br) – Blue (L)r/min Unloaded LoadedCranking 1,500 3,500DC V 144 137 169 129Charge coil resistance (use as reference):Brown (Br) – Blue (L)272–408 Ω at 20 °C (68 °F)Digital multimeter: YU-34899-ADigital circuit tester: 90890-03174Peak voltage adaptor:YU-39991 / 90890-03172Test harness (2 pins):YB-06767 / 90890-06767Pulser coil output peak voltage:White/red (W/R) – White/black (W/B)r/min Unloaded LoadedCranking 1,500 3,500DC V 6.3 3.5 7.4 11.2Pulser coil resistance (use as reference):White/red (W/R) – White/black (W/B)396–594 Ω at 20 °C (68 °F)Pulser coil air gap:0.5–1.0 mm (0.020–0.039 in)Ignition system and Ignition control system
