  1. To remove the voltage due to surface charging (ECU. capacitor etc.), turn the headlight switch to ON with IG OFF for about 20 or 30 seconds.
  2. Measure the battery voltage between the terminals.
    Voltage: 12.5 V or more (Electrolyte temperature: 20°C)
3. Battery electrolyte level check
  1. Check the electrolyte level of each cell and refill distilled water or replace the battery if the level is below the LOW level.
4. Battery electrolyte specific gravity check
  1. Check the electrolyte specific gravity in each cell.
    Standard value: 1.25 to 1.29 (Electrolyte temperature: 20°C)
NG: Go to Step 5.

OK: Go to next step
Starter check
