AC Outlet Troubleshooting Guide

Most Timberleaf trailers include 120V AC outlets for use when you’re plugged into shore power. Here’s how the power flows:

Power Flow Chain:
Exterior power port → Breaker panel → Galley GFCI outlet → Cabin outlet

---

Tools Needed

• Digital multimeter

• #2 square drive screwdriver

• Heavy leather gloves (for safety when working near live circuits)

---

Step 1: Safety First

• Unplug shore power before opening any electrical panels or outlets.

• Always work with care around 120V systems. If you’re unsure, contact Timberleaf support or a qualified RV electrician.

Step 2: Open the Breaker Panel

1. Locate the breaker panel:

   • The panel is accessed in the cabin at the foot of the bed (not in the galley).

2. Remove the panel cover:

   • Find the single brass screw securing the plastic cover.

   • Use a #2 square drive screwdriver to remove it.

   • Carefully remove the cover to expose the breakers.

3. Identify the breakers:

   • There are three breakers, from left to right:

     1. Main breaker (incoming power)

     2. Outlet breaker

     3. Charger breaker

---

Step 3: Test for Incoming Power

1. Plug in shore power cord.

2. Wear gloves for safety: There will now be live voltage in the panel.

3. Set your multimeter to AC voltage.

4. Check the outlet breaker:

   • Place one probe on the screw at the bottom of the center (outlet) breaker.

   • Place the other probe on the neutral bus bar (where a group of white wires are attached).

   • You should see 110–120 volts.

5. If you do not see voltage:

   • Test the main breaker (leftmost) in the same way.

   • If voltage is present at the main but not at the outlet breaker, the problem is likely with the breaker or its wiring.

Step 4: Test the Galley GFCI Outlet

1. Move to the galley GFCI outlet (the one with “Test” and “Reset” buttons).

2. Test the outlet:

   • With your meter, carefully probe the two vertical slots.

   • You should see 110–120 volts.

   • If no voltage: proceed to the next step.

Step 5: Inspect the GFCI Outlet Wiring

A note about GFCIs:
GFCI outlets have two sets of terminals:

• LINE: Power coming in from the breaker.

• LOAD: Power going out to protect other outlets downstream (like the cabin outlet).
  If the GFCI itself fails, it can block power to both the outlet and any connected downstream outlets.

---

1. Unplug shore power again for safety.

2. Remove the GFCI from the wall:

   • Take off the cover plate and two mounting screws.

   • Pull the outlet forward, leaving the wires connected.

3. Plug shore power back in, use gloves, and use caution.

4. Test the terminal screws on the GFCI:

   • Probe between the brass screw (hot/LINE) and the steel screw (neutral/LINE).

   • If you see voltage here, but not at the outlet slots:

     • The GFCI has likely failed internally and needs replacement.

   • If you do not see voltage:

     • The issue is likely upstream—possibly at the breaker or wiring.

---

Step 6: Next Steps

• If the GFCI outlet is faulty:
  Timberleaf can supply a replacement if your trailer is still under warranty. If not, we’re happy to sell you the correct part and walk you through installation.

• If the issue is upstream:
  Contact Timberleaf support with your test results for further guidance.

Important Safety Notes

• Never work inside an electrical panel while power is connected unless you are confident in your abilities and are wearing appropriate protection.

• If in doubt, it’s always best to have a professional RV technician handle the repair.
