Intermittent no-start, parasitic draw, chasing a fault code, harness damage. Electrical is the work where 30 years of doing it shows up — we follow the wire, not the guess. Services: ECM and chassis fault code diagnostics, battery testing and replacement, alternator and starter repair, wiring harness inspection and repair, lighting repair (headlights, signals, ABS, trailer 7-way), and charging and grounding system testing.
Modern diesel electrical isn't just battery and starter — it's CAN bus, ECM strategy, sensor inputs, ground integrity. We pull the codes, read the freeze frame data, and chase the root cause to the failed component. 30 years on Class 4-8 means we've seen the failure mode before.
