Disconnecting House Batteries from the Travel Trailer’s Electrical System
Disconnecting your house batteries is equally important, especially for extended periods of storage. This prevents parasitic drain, which can slowly discharge your batteries over time, leaving you with a dead battery when you need it. Follow the same safety precautions mentioned earlier. Remember to disconnect the negative cable first, then the positive cable.
Visual Guide: Dual Battery System Wiring
Imagine a diagram showing two 12-volt batteries labeled Battery 1 and Battery 2. Each battery has a positive (+) and negative (-) terminal. From the positive terminal of each battery, a heavy-gauge red wire runs to a bus bar (a central distribution point). Similarly, from the negative terminal of each battery, a heavy-gauge black wire runs to the same bus bar.
From the bus bar, additional wires branch out to the various components in the travel trailer’s electrical system, such as the converter, inverter, and other appliances. The positive wires are all connected to one side of the bus bar, and the negative wires are connected to the other side. A main positive and negative cable runs from the bus bar to the battery switch.
The battery switch then connects to the trailer’s electrical system. This setup allows for parallel connection of the batteries, increasing the overall amperage capacity. Each connection should be secured with appropriate connectors and tightened to prevent loose connections. All wiring should be properly insulated and protected from abrasion.
Common Mistakes When Connecting or Disconnecting Batteries
A common mistake is connecting the negative cable first, which can create a spark and potentially ignite flammable gases. Another frequent error is using undersized cables, which can lead to overheating and voltage drops. Failing to secure connections properly can result in loose connections, causing intermittent power or even short circuits. Finally, neglecting safety precautions, such as not wearing safety glasses or gloves, can result in serious injury.
