Electrical Diagnostics

Heavy-duty electrical diagnosis and repair. Starting, charging, body, and J1939 datalink troubleshooting.

The Work

How we do it.

Electrical gremlins almost always trace back to grounds and cable corrosion. We start at the battery, work outward, and don't stop until the meter says what it should.

ECM and datalink issues get the right tooling, not parts-cannon guessing. You get a fix and an explanation of how we found it.

What's Included
  • Starter and alternator R&R
  • Battery bank and cable replacement
  • Ground strap and junction block service
  • J1939 datalink and ECM diagnostics
  • Trailer 7-way and harness repair
