Battery: Testing and Inspection
Electrolyte Level1. Check whether or not the electrolyte level lies between "UPPER LEVEL" line and "LOWER LEVEL" line.
2. If low, add distilled water to "UPPER LEVEL" line. Do not overfill.
Specific gravity of electrolyte
1. Measure specific gravity with a hydrometer.
Specific gravity: 1.27 - 1.29 (at 77 °F [25 °C])
Discharge Test:
Discharge test
Terminal and cable
1. Check that battery terminal connections are tight to ensure good electrical connections.
2. Check for corroded or frayed battery cables.
3. Check rubber protector on positive terminal for proper coverage.
Inspection:
4. Clean terminals, if necessary, and lightly coat them with grease.
