REMOVAL AND INSTALLATION OF BATTERY TERMINAL

Before performing electronic work, disconnect the battery negative (-) terminal cable in order to prevent it from shorting and burning out.
When disconnecting and reconnecting the battery cable, turn the ignition switch and lighting switch off and loosen the terminal nut completely. Perform operations without twisting or prying on the terminal.
