The battery cables must be clean and tight [Figure 50-20-2]. Remove acid or corrosion from the battery and cables using a sodium bicarbonate and water solution.
Cover the battery terminals and cable ends with battery saver grease to prevent corrosion.
Check for broken or loose connections.
If the battery cables are removed for any reason, disconnect the negative (-) cable first. When installing the battery cables, make the last connection the negative (-) cable to the battery.
The original equipment battery is maintenance free. If a replacement battery is installed, check the electrolyte level in the battery.
If the electrolyte level is lower than 13 mm (0.50 in) above the plates, add distilled water only.
