Installation：
1. Safely park the machine on level ground and shut down the engine completely.
2. Disconnect the main battery cables (negative terminal first) to avoid any risk of short-circuiting during installation.
3. Access the master disconnect panel, tag and unfasten the wires connected to the old switch terminals.
4. Mount the new 7N-0718 switch firmly onto the panel bracket.
5. Reattach the heavy-duty wiring harnesses to the stud terminals and tighten the securing nuts to specification to prevent high-resistance contact.
6. Reconnect the battery terminals and verify the switch reliably cuts off and restores the machine’s primary power.
