Setup and Initial Use
Connecting the Surge Protector
- Step 1: Plug into AC Power. Insert the male end of the GEARGO RV Surge Protector into the AC power pedestal outlet. Ensure a firm connection. Do not connect your RV at this stage.
- Step 2: Verify Wiring Condition. Observe the LED indicators on the surge protector. The correct wiring condition is indicated when both green LEDs are illuminated. If other LEDs are lit or no LEDs are lit, refer to the "Circuit Analyzer Diagnostic Chart" below to identify the fault.
- Step 3: Connect RV. Once the circuit analyzer indicates correct wiring (both green LEDs on), you can safely plug your RV's power cord into the female receptacle of the surge protector.

Operating the Circuit Analyzer
The integrated circuit analyzer provides immediate feedback on the power pedestal's wiring status through a series of LED indicators. This diagnostic feature helps prevent damage to your RV's electrical system from common wiring faults.

Troubleshooting
- Problem: No LEDs illuminate when plugged into the power pedestal.
- Solution: This indicates an open circuit or no power at the pedestal. Check the circuit breaker at the pedestal. If the issue persists, try a different pedestal or contact park management.
- Problem: Red LEDs are illuminated, or only one green LED is on.
- Solution: This indicates a wiring fault (e.g., open ground, reverse polarity). Refer to the "Circuit Analyzer Diagnostic Chart" to identify the specific fault. Do not connect your RV to this power source. Contact park management or use an alternative power source.
- Problem: Surge protector feels warm during operation.
- Solution: A slight warmth is normal during operation. However, if the unit becomes excessively hot, disconnect it immediately and inspect for any issues. Ensure proper ventilation and that the unit is not overloaded.
- Problem: Protective cover does not close properly.
- Solution: Ensure no debris is obstructing the hinge or latch mechanism. Gently clean the area. If the cover is damaged, contact customer support.
