Inspection of the Battery

Inspection of the Battery - Ops

Inspect the battery as follows:

  1. Check for cracks in the battery cases (1), for tightness of the cable clamps (2) at the terminals, and for corrosion of the terminals (3). Service or replace as needed.

    Warning: PERSONAL INJURY

    To avoid injury from accidental engine startup while servicing the engine, disconnect/disable the starting system.

  2. Keep the terminal surface clean.
  3. Inspect the cables, clamps and hold-down brackets regularly. Clean and reapply a light coating of petroleum jelly when needed. Have corroded or damaged parts replaced.
  4. If the engine is to be out of service for more than 30 days, remove the batteries and store in a cool, dry place.
    1. Keep batteries fully charged, if possible.
    2. Replace any battery that fails to hold a charge.
  5. Periodically check battery connections for corrosion and tightness.
    1. If necessary, remove connections and wire brush any corrosion from terminals and cable ends.
    2. Replace damaged wiring.
