Failure diagnosis procedure when the storage battery is undercharged
Yes
Adjust or replace the brake
lamp switch
Leakage current is less than the specified value
Check if the charging coil of magnetor is
shortcircuited

Replace the
charging coil
Storage battery is undercharged
Check if the brake lamp is on
Put the ignition switch in ―OFF‖ position, remove the negative pole wire from the
storage battery, connect the ammeter negative pen to the negative ternminal of storage
battery and positive pen to the negative pole wire to check the leakage current
1. Check if the electrolyte in the storage battery
is insufficient
2. Check if electrolyte concentration in the
storage battery is too low
3. Check if the polar plate in the storage battery
is sulfurized or shortcircuited
