My accessories are not receiving power

Verify the Garmin PowerSwitch device is receiving power from the vehicle battery.
Verify that your vehicle's battery is supplying at least 12 V of power. The Garmin PowerSwitch device turns off all outputs automatically to preserve your vehicle's battery if it is receiving less than 11 V of power. Outputs turn back on when the device detects more than 12 V of power.
Verify that all electrical connections are secure and will not come loose while operating the vehicle.
Verify that each connected accessory draws less than 30 A. If an accessory draws more than 30 A, the device turns off that output automatically.
Verify that the total system load is less than 100 A. If the device detects a system load of more than 100 A, it turns off all outputs automatically.
Inspect all electrical connections for an electrical short circuit.
