Replacing an inverter in a 2005 RV without a title can be a daunting task, but it’s certainly not impossible. Before diving into the process, it’s crucial to assess if you have the necessary tools, knowledge, and safety precautions in place. With a little preparation and careful execution, you can successfully replace your RV’s inverter without breaking the bank or running into legal trouble.
To obtain a replacement inverter, you have several options. You can purchase a new one from an RV dealer or online retailer. However, if you’re on a budget, consider looking for a used inverter at a salvage yard or online marketplace. Once you have your new inverter, you’re ready to start the replacement process. Remember to disconnect the battery before proceeding to ensure your safety.
The actual replacement procedure involves removing the old inverter and installing the new one in its place. Before disconnecting the old inverter, take note of the wiring configuration to ensure you connect the new inverter correctly. Once the old inverter is removed, clean the mounting surface and prepare it for the new one. Follow the manufacturer’s instructions for mounting and wiring the new inverter, and once it’s securely in place, you’re ready to reconnect the battery and test the system. With the new inverter operating smoothly, you can enjoy a reliable power source in your RV without the worry of an outdated or malfunctioning unit.
Identifying and Removing the Old Inverter
Locate the inverter: The inverter is typically installed in a compartment or storage area of the RV. Check near the electrical panel, battery bank, or other electrical components.
Turn off power: Disconnect the shore power cord to the RV and turn off all electrical appliances and lights.
Disconnect the Old Inverter
Disconnect the battery cables: Locate the positive (+) and negative (-) battery cables connected to the inverter. Use a wrench or socket set to loosen and remove the nuts securing the cables.
Unplug the AC input and output wires: Follow the AC wires connected to the inverter. These wires will typically be thicker than the DC wires. Unplug the wires by pressing on the release tabs or levers on the connectors.
Remove the mounting bolts: Locate the bolts or screws securing the inverter to its mounting bracket or chassis. Use a wrench or screwdriver to remove these bolts or screws.
Carefully lift the inverter out of place: Once the cables and bolts are disconnected, gently lift the inverter out of its compartment or mounting location.

Connecting the Inverter to the Battery
Connect the positive terminal of the inverter to the positive terminal of the battery. Connect the negative terminal of the inverter to the negative terminal of the battery. Ensure proper connections by using high-quality cables with appropriate gauge to handle the power requirements of the inverter. A poorly connected battery may result in power loss, damage, or potential fire hazards.
Securing Connections
Secure all connections with proper clamps or terminals. Loose connections can lead to voltage drop, increased resistance, or even electrical arcing if not adequately tightened. Ensure a snug fit and avoid any loose ends or frayed wires. A stable connection will help prevent any power loss or electrical hazards.
Checking Polarity
Double-check the polarity before connecting the inverter to the battery. Incorrect polarity can cause damage to the inverter, battery, or connected appliances. Use a multimeter or voltage tester to confirm the proper polarity of the connections. A simple polarity test can save you from any costly mistakes or potential safety concerns.
Fuse or Circuit Breaker Protection
Install an appropriate fuse or circuit breaker between the battery and the inverter. This serves as a safety measure to protect the inverter and electrical system from overcurrent or short circuits. The fuse or circuit breaker should be rated for the maximum current draw of the inverter. Consult the inverter manufacturer’s specifications for the recommended fuse or circuit breaker size.
Remember, when working with electrical systems, it’s crucial to follow safety precautions. Wear appropriate protective gear, such as insulated gloves, and ensure the work area is properly ventilated. If you’re not confident in handling electrical connections, it’s wise to consult a qualified electrician for assistance.
Connecting the Inverter to the RV’s Electrical System
Before connecting the inverter to the RV’s electrical system, it is important to ensure that the inverter is properly grounded. This can be done by connecting the inverter’s ground terminal to the RV’s chassis.
Once the inverter is grounded, it can be connected to the RV’s electrical system. The inverter should be connected to the RV’s battery bank, and the RV’s electrical system should be connected to the inverter’s output terminals.
Once the inverter is connected, it can be turned on. The inverter will now begin to convert the DC power from the RV’s battery bank to AC power, which can be used to power the RV’s electrical appliances.
Step by Step Guide to Connecting the Inverter:
1. Turn off the RV’s electrical system.
2. Connect the inverter’s positive terminal to the positive terminal of the RV’s battery bank.
3. Connect the inverter’s negative terminal to the negative terminal of the RV’s battery bank.
4. Connect the RV’s electrical system to the inverter’s output terminals.
5. Connect the inverter to a grounded outlet. Turn on the inverter and test it by plugging in an appliance.
| Step | Description |
|---|---|
| 1 | Turn off the RV’s electrical system. |
| 2 | Connect the inverter’s positive terminal to the positive terminal of the RV’s battery bank. |
| 3 | Connect the inverter’s negative terminal to the negative terminal of the RV’s battery bank. |
| 4 | Connect the RV’s electrical system to the inverter’s output terminals. |
| 5 | Connect the inverter to a grounded outlet. Turn on the inverter and test it by plugging in an appliance. |
