We understand the high electrical demands of fleet trucks and service your vehicles with specialized care, providing a high level of workmanship you can trust for charging systems, starters, and lighting systems.

Fleet Electrical Repair & Maintenance Services

Batteries & Cables

For heavy-duty fleet trucks, we offer specialized, high-amperage replacement batteries and cables designed to handle the significant power demands of starting a diesel engine and running complex onboard systems. Call or stop by RG Diesel, LLC, and we will ensure you find the best fit and highest quality components for your vehicle's demanding electrical requirements.

Breakers & Fuses

The complex electrical systems of diesel fleet vehicles rely on robust breakers and fuses to protect sensitive and costly components from power surges and shorts. We carry a wide assortment of commercial-grade breakers and fuses to meet your fleet's specific electrical protection needs.

Lights

Given that fleet vehicles often operate day and night, proper lighting is crucial for safety and compliance. RG Diesel, LLC carries a variety of reliable lights, including powerful forward illumination and marker lights, to ensure your diesel truck provides clear visibility and full compliance.

Spark Plugs

Since diesel engines operate using compression ignition, they do not utilize traditional spark plugs but instead rely on glow plugs to heat the combustion chamber for starting in cold weather. When these critical glow plugs wear out, they impede starting and require expert replacement, which is a service provided by our professionals.

Starters & Alternators

The starter converts electrical energy to mechanical energy for engine turnover, and the alternator recharges your heavy-duty battery system, both of which face immense strain in diesel applications. If you are looking for a commercial-grade starter or alternator for your fleet vehicle, the experts at RG Diesel, LLC are ready to help you with quality replacement and installation.

Wiring & Switches

Faulty wiring and switches are common culprits behind persistent electrical issues in older or heavily used fleet vehicles, leading to component failure and intermittent problems. RG Diesel, LLC has qualified service professionals waiting to help you diagnose and replace faulty wiring and switches on your diesel fleet, ensuring reliable operation of all electrical systems.
