Mechanical
Operating conditions, wear, motion, pressure, heat, and physical evidence.
Complex failures do not respect trade boundaries. RootSignal follows mechanical, electrical, controls, network, and software evidence until the actual cause can be defended.
Operating conditions, wear, motion, pressure, heat, and physical evidence.
Power, grounds, loading, signal integrity, harnesses, and sensors.
Sequence, interlocks, logic, timing, and networked controllers.
Communication paths, field buses, gateways, and intermittent connectivity.
Configuration, protocol behavior, data paths, and system integration.
Separate observed behavior from assumptions, previous repairs, and inherited explanations.
Collect signals, conditions, sequence, and context without disturbing the evidence.
Connect physical behavior to electrical response, control decisions, network traffic, and software state.
Verify the cause, document the chain, and leave the system easier to understand.
The failure disappears during ordinary inspection or returns after another repair.
Each component appears functional, but the assembled system still does not behave correctly.
Sequences, controls, communication, and physical behavior disagree under real operating conditions.
A technically defensible account is needed before more parts, labor, or confidence are spent.
Start with the observed failure, what has already been tried, and what the system was doing when it happened.
