Wiring Instructions:
The Grote 82-1905 features three blade terminals for connection. Refer to the diagram below for typical wiring configurations. The terminals are typically labeled or can be identified by their function:
- Power (Input): Connect this terminal to the positive (+) power source (e.g., battery, fuse box).
- ACC (Accessory/Load): Connect this terminal to the positive (+) lead of the device or accessory you wish to power (e.g., lights, fan).
- Ground: Connect this terminal to a reliable chassis ground or negative (-) terminal of the power source. This connection is essential for the illumination feature to function.

Important: Ensure all connections are secure and insulated to prevent short circuits. Use appropriate fuses in your circuit to protect the switch and connected devices.
Operating Instructions
The Grote 82-1905 is an ON-OFF toggle switch, providing simple control over your electrical circuit.
- To Turn ON: Push the toggle lever to the "ON" position. The switch's internal illumination will light up, indicating that power is flowing to the connected accessory.
- To Turn OFF: Push the toggle lever to the "OFF" position. The illumination will turn off, and power to the connected accessory will be interrupted.
The switch is designed for momentary or continuous use within its specified voltage and current ratings.
Maintenance
The Grote 82-1905 toggle switch is designed for durability and requires minimal maintenance. However, periodic checks can ensure its longevity and reliable performance.
- Cleaning: Use a dry, soft cloth to wipe the exterior of the switch. Avoid using harsh chemicals or abrasive cleaners, which can damage the finish or internal components.
- Connection Check: Periodically inspect the wiring connections to ensure they remain secure and free from corrosion. Loose connections can lead to intermittent operation or overheating.
- Environmental Protection: While robust, avoid exposing the switch to excessive moisture, dust, or extreme temperatures beyond its operating specifications, unless it is specifically rated for such conditions.
Troubleshooting
If you encounter issues with your Grote 82-1905 toggle switch, consider the following troubleshooting steps:
| Problem | Possible Cause | Solution |
