ELECTRICAL SYSTEM
Shift the transmission to the neutral position, turn the ignition switch to the "ON" position Press the starter button and allow the engine to turn for few seconds, and then measure the pickup coil and signal coil peak voltage Repeat the above procedure few times and measure the highest pickup coil and signal coil peak voltageTester knob indication: Voltage) Pickup coil peak voltage: More than 2.0 Signal coil peak voltage: More than 0.1 PICKUP COIL AND SIGNAL COIL RESISTANCE Disconnect the generator coupler Measure the resistance between the lead wires using the multi circuit testerIf the resistance is not within the spcified value, the pickup coil and signal coil must be replaced09900-25008: Multi circuit tester set Tester knob indication: Resistance () Pickup coil resistance: 350 670 (Blue Green) Signal coil resistance: 0.09 0.5 (Black White)
