Factors that cause computer board damage
The most common causes of computer board damage are water ingress and mechanical impact. Lightning strikes, welding surges, pin corrosion, and internal component burnout can also cause damage. A common approach to preventing welding surges is to disconnect the entire power supply to the machine, specifically by disconnecting the battery. Some manufacturers even require users to disconnect the computer board from the wiring harness before welding. Pin corrosion is most often caused by poor sealing of the main connector on the computer board, allowing water to enter. Over time, this can lead to pin breakage or poor contact.
Generator failure, resulting in high voltage in the circuit.
The user connected batteries in series when starting the engine.
Misuse of a high-capacity fuse.
Unauthorized electrical connections, increasing the load and causing burnout due to excessive current.
Incorrect battery positive and negative terminals, aging wiring harness, shorts, or poor grounding.
Failure to perform maintenance by plugging or unplugging the ECM while it is powered on.
Excavator digging through cables, causing external high-voltage shock.
Generator regulator failure, resulting in excessive generator power generation.
