Wiring
Trailer wiring
Electric brakes
Corroded connectors, damaged harnesses, failed breakaways, and miscalibrated brake controllers are common field finds. We test circuits properly and fix the fault — not just the most visible symptom.
Trailer wiring
What we repair
Lights & signals
Running, brake, turn — traced from connector to lamp.
Harness inspection
Road debris, moisture, UV, and chafe along the trailer length.
Adapters & tow-vehicle side
Permanent adapters/upgrades; tow-vehicle wiring with proper fusing and grounds.
Electric brakes
Stopping power that works
Controller calibration
Under-brake (trailer pushes) vs over-brake (lockup) — output verified.
Magnet testing & replacement
Wear, burnout, open/shorted windings that kill braking on one or more wheels.
Brake wiring & adjustment
Continuity/voltage/current at each magnet; shoe clearance adjusted as wear progresses.
Breakaway system
Battery-powered emergency actuation if the trailer separates — most owners never test it. We do.
Pre-trip / post-purchase trailer safety inspections cover connector, magnets, breakaway, lights, and adjustment so the rig is road-legal and road-safe.
