Symptom Troubleshooting Guide
T-Series truck units live a hard life: vibration, washdowns, and road salt reach the controller long before the rest of the electronics. Most boards we receive show environmental damage rather than a single failed part.
| Symptom | Likely Causes | How We Repair It |
|---|---|---|
| Intermittent power loss or random resets | Board corrosion; relay logic faults; connector fretting | Ultrasonic cleaning, trace repair, relay-stage rework, and new conformal coating |
| Controller dead after washing the unit | Water intrusion past aged seals into the board | Decontamination, corroded-component replacement, and re-waterproofing |
| Relays click but the unit won’t start | Relay drive logic faults; burned contacts; cracked joints under the relays | Relay logic repair and replacement with verified switching under load |
Frequently Asked Questions
Is a corroded T-Series controller worth repairing?
In most cases yes. Corrosion damage looks dramatic but is usually limited to traces and a handful of components. We clean, repair, and re-coat the board — typically at a fraction of the replacement price, with a 1-year warranty.
Can you make the repaired board more water-resistant than the original?
Yes. Re-waterproofing with fresh conformal coating is part of our standard T-Series process, and we upgrade protection components where the original design is a known weak point.
