Expert Diagnostics. Flawless Wiring.

Electrical issues are among the most frustrating problems a trailer owner can face. A persistent short, flickering clearance lights, or a battery that won't hold a charge can delay your workday or ruin a camping trip. At Total Trailer, we take the guesswork out of 12V and 120V electrical systems.

Our RVTI Master Certified technician has the specialized tools and training to track down complex wiring faults that standard mechanics often miss. Whether you need a simple 7-way plug replaced, a complete rewire of a cargo trailer, or a custom LED lighting package installed, we guarantee clean, secure, and weather-tight electrical work.

Frequently Asked Questions About Trailer Electrical

  • Why do my trailer lights flicker or only work sometimes?
    Intermittent lighting issues are almost always caused by a poor ground connection. Trailers rely on the frame to ground the electrical circuit; if a ground wire is loose, corroded, or making poor contact with the chassis, the lights will flicker or fail. We can trace and secure all ground points for a permanent fix.

    Can you upgrade my old incandescent trailer lights to LEDs?
    Yes, upgrading to LED lighting is one of the best investments you can make. LEDs are significantly brighter (improving safety), draw a fraction of the power from your battery, and are much more durable against road vibrations. We offer full LED conversion packages.

    My trailer battery isn't charging when I'm plugged into shore power. Why?
    This usually points to a failure in your RV or trailer's converter (the device that changes 120V AC shore power into 12V DC power to charge the battery). It could also be a blown reverse-polarity fuse or a deeply discharged battery that won't accept a charge. Our technicians can test the full electrical path to isolate the failure.
