Generic Race 50 - Voltage and Current Regulator

73
are disassembled to the main fuse.
Start the engine and measure the clamping voltage and current when the rotation speed gradually increases.
Clamping voltage/rotation speed ：14-15V （2500rpm）
If the clamping voltage exceeds the specified value range,
inspect the voltage regulator.
Inspect the clamping voltage of the lighting system.
*Attention
Set the avometer at the alternating voltage position.
Clamping voltage ：13.1±0.5V/2500rpm
If the clamping voltage exceeds the specified value range, inspect the voltage and current regulator.
1.5 Voltage and current regulator
1.5.1 Inspect the main wire circuit
Disassemble the 4P plug of the voltage and current regulator.
Inspect the conduction between main wire terminals with the
following methods.
