Wiring & Lighting Repair

Wiring & Lighting Repair Services

At Apparatus Central Repair, LLC, we provide professional wiring and lighting repair for fire trucks, fire engines, and ambulances throughout Michigan. Emergency vehicles depend on reliable electrical systems to operate safely, and our team specializes in diagnosing and repairing the complex wiring and lighting components found in today’s fire apparatus. From warning lights and scene lights to wiring harnesses and control panels, we ensure your equipment works correctly every time you respond.

Emergency Vehicle Electrical System Services

Our technicians identify the root cause of electrical issues and provide long-lasting repairs using high-quality materials designed for fire apparatus. We help prevent power loss, flickering lights, blown fuses, and intermittent electrical problems that put your crew and community at risk.

Scene Lighting Repair and Installation

Effective scene lighting helps crews work safely at night or in low-visibility conditions. We repair and install all types of fire apparatus scene lighting, including floodlights, telescoping lights, perimeter lighting, and compartment lighting. Our technicians also perform LED conversions to increase brightness and reduce maintenance costs. With reliable scene lighting, your team can perform their duties more safely and efficiently during nighttime operations.

Fire Apparatus Wiring Repair and Replacement

We offer complete wiring repair and replacement solutions for fire trucks and ambulances. Over time, wiring can become worn, brittle, corroded, or damaged from heat and vibration. Our team repairs shorts, replaces faulty connectors, upgrades outdated wiring, and restores proper grounding and power distribution. Whether you need a single section of wiring repaired or an entire harness replaced, we ensure your electrical system is safe, clean, and reliable.

Preventive Electrical Maintenance for Fire Apparatus

Regular electrical maintenance helps prevent sudden failures and costly downtime. Our preventive services include full electrical inspections, corrosion treatment, voltage testing, diagnostics of control systems, and recommendations for necessary repairs or upgrades. Proactive electrical maintenance is one of the best ways to extend the life of your apparatus and reduce the risk of emergency-scene failures.

Pump Panel, Switch, and Control Diagnostics

Fire trucks and ambulances rely on numerous switches, relays, and control panels to operate key systems. When a switch fails or a circuit board malfunctions, it can prevent your apparatus from performing as intended. We diagnose issues with pump panel controls, cab switches, electronic modules, relays, and electrical controllers. Our repairs restore smooth, dependable operation of all electrical controls and ensure your systems respond correctly when needed.

Battery, Charging, and Power System Repairs

A stable power supply is essential for emergency vehicles, especially during prolonged operations. We service battery wiring, charging systems, alternators, inverters, fuse blocks, and load management systems to ensure consistent power distribution. If your apparatus is experiencing battery drain, charging issues, or uneven power output, our team provides fast, accurate repairs to keep your vehicle operating at full capacity.

Warning Light Repair and LED Upgrades

Your warning lights are essential for visibility and safety while responding to emergencies. We repair and upgrade lightbars, grille lights, intersection lights, flashers, and LED modules for all major brands.
