Observe the symptom
Start with what the equipment is actually doing, not what the fault is assumed to be.
ProbeLemEvidence before assumptions
Marine electrical troubleshooting, documented from the field.
I am Lem, a traveling Fleet ETO. ProbeLem follows the real work of finding electrical faults at sea, understanding what caused them, and proving the equipment is ready to return to service.
Documentary fieldwork, case studies, and practical tools for the people who keep equipment running.

A reading becomes useful when it is connected to context.
The goal is not to make every measurement pass or fail. The goal is to preserve the evidence, apply the right source, and make the next decision defensible.
