otherwise sensitive electrical components will be damaged.
• Do not interrupt voltage-carrying circuits at the battery terminals – sparking hazard!
• Never place tools or other conductive articles on the battery – short circuit hazard.
• Disconnect the negative (–) battery terminal from the battery before starting repair work
on the electrical system.
