Replacing the brake coil on a Warner 50 series electric trailer brake can seem daunting, but with the right guidance, it’s a manageable DIY project. This guide will walk you through the process, from diagnosis to completion, offering expert tips and insights for a successful warner 50 series brake coil replacement.
Understanding the Warner 50 Series Brake Coil
The brake coil is the heart of your Warner 50 series electric trailer brake system. It’s an electromagnet that, when energized, creates a magnetic field, pulling the magnet and actuating the brakes. A faulty coil can lead to a variety of issues, from weak braking to complete brake failure. Understanding its function is crucial for proper warner 50 series brake coil replacement.
Diagnosing a Faulty Brake Coil
Before you jump into a warner 50 series brake coil replacement, it’s important to confirm that the coil is indeed the culprit. Common symptoms of a bad brake coil include:
- No or weak braking: This is the most obvious sign. If your trailer brakes aren’t engaging properly, a faulty coil is a likely cause.
- Overheating brakes: A shorted coil can draw excessive current, leading to overheating.
- Burning smell: An overheating coil can emit a distinct burning smell.
- No continuity with a multimeter: Testing the coil with a multimeter will reveal if there’s an open circuit.
