1.5.2 Voltage-current regulator check
When the main cable is inspected to be normal, check whether the plug of the voltage/current regulator is in good
contact. Measure impedance between terminals of the voltage/current regulator.
* Note
• Do not touch any metal part of the test rod of the multimeter with your finger for check.
• Check with multimeter. Different multimeters show different impedance and different results.
Replace the voltage-current regulator when the impedance between terminals is abnormal.
1.6 Magnetor charging coil
* Note
Check the magnetor charging coil on the engine.
