At Eyre Heavy Duty, our technicians specialize in electrical troubleshooting for heavy-duty trucks, medium-duty vehicles, buses, RVs, and commercial fleets across Maryland. From starting and charging problems to advanced computer faults and wiring failures, we pinpoint the issue quickly and get your vehicle safely back on the road.
Modern commercial vehicles rely on complex electrical and electronic systems. A single failing sensor, loose ground, or shorted wire can create performance problems, warning lights, or complete vehicle shutdowns.
Using dealer-level diagnostic tools for major brands—including Freightliner, International, Peterbilt, Volvo, Kenworth, and Ford—our team identifies the true cause of electrical system failures and provides fast, effective repairs.
Electrical problems in trucks, RVs, and motorhomes can be unpredictable and costly if not diagnosed correctly. At Eyre Heavy Duty, our certified technicians provide fast, accurate electrical diagnostics and repairs for all major vehicle systems, helping prevent downtime and unnecessary part replacements. Using industry-leading diagnostic software, we access live data, fault codes, system histories, and vehicle communication networks to identify issues quickly and efficiently.

Our technicians provide electrical repairs as part of regular maintenance, emergency service needs, and full fleet troubleshooting programs.
Yes. A no-start condition can involve batteries, cables, connections, starter or charging systems, fuses, wiring, sensors, control modules, communication networks, or other vehicle systems. Eyre performs electrical and diagnostic testing to identify the cause before recommending repairs.
Intermittent electrical problems can be caused by loose or corroded connections, damaged wiring, weak grounds, moisture intrusion, failing sensors or modules, voltage irregularities, or communication faults. Because the fault may not be present continuously, diagnosis may require code scanning, circuit testing, visual inspection, and testing under operating conditions.
Eyre diagnoses warning lights and related faults on commercial trucks and other qualifying vehicles. A warning light identifies a system that needs attention, but it does not by itself confirm which component needs replacement; diagnostic testing is used to identify the underlying cause.
Yes. Electrical diagnostic service can include battery testing, charging-system testing, alternator and starter evaluation, wiring and connection inspection, and investigation of abnormal battery drain. The required testing depends on the vehicle and symptoms.
Eyre can diagnose trailer-lighting, connector, wiring, brake-light, and related electrical concerns within its service scope. When scheduling, explain the truck-and-trailer combination and the symptoms so the team can plan the appropriate inspection.
