b. Charging Regulator
Loosen the positive battery cable when starting the engine and connect a DC current meter between the
positive cable and positive terminal. The indicated current cannot exceed 1.5A. If there is no current
present, replace the regulator
● Make sure the AC input voltage of charger is normal when check the charging regulator.
● Check the Cathode connection current of battery with DC meter when the battery wire is connected.

c. Timing relay
Put the ignition switch on the “OFF” position, connect a voltmeter to the white and yellow/green wires.
Place the ignition switch in the “ON” position, hold on for 7 seconds and then place in the “OFF” position.
A reading of 12V should be present for 7~12 seconds then the output should drop to 0 volts.
● Connect the sufficient battery before inspecting. On-line measurement can not be disconnected to the
connectors.
● Measure after the engine stopped more than one minute.
