- Headlights or other lights are not working

Electrical issues can be tricky because they often affect multiple systems. At RG Diesel, LLC, we combine deep diesel knowledge with diagnostic expertise to deliver electrical repairs that are accurate and long lasting. Our technicians understand how electrical problems interact with diesel engines and drivetrains, giving you confidence that the job is done right.
Electric issues left unaddressed can lead to major failures. Regular electrical system checks help preserve battery life, prevent unexpected shutdowns, and support peak performance
Why is my diesel truck not starting but the lights still work?
This can indicate a weak battery, bad starter, or poor connection. We test each component to identify the cause.
How often should I check my battery and charging system?
A basic check at every major service interval helps catch problems before they leave you stranded.
Can electrical problems affect fuel economy?
Yes. Sensors and computer systems that run engine functions can cause poor fuel performance if they are not working properly.
Are electrical repairs more common in cold weather?
Cold temperatures put extra strain on batteries and starter systems, which can reveal weak components.
