Troubleshooting coach
Choose the next safe measurement instead of guessing.
A guided low-voltage fault-finding coach for dead projects, heat, audio faults, intermittent faults, fuse trips, and battery sag.
Safety first, always.
ElectroLab AI teaches theory, low-voltage electronics, and planning concepts. Mains voltage, switchboards, fixed wiring, high-current systems, and legal electrical work must only be performed by licensed electricians where required.
Open Safety CenterTroubleshooting coach
Pick the symptom. Choose what you observed. Measure the next safe point.
This is a low-voltage electronics coach, not permission to work on mains, switchboards, fixed wiring, or legal electrical work.

Symptom
Project is dead
No lights, sound, movement, or response from a low-voltage project.
First safe move
Measure voltage at the source, then after the switch or fuse, with the meter in voltage mode.
Battery or adapter
Switch/fuse
Input jack
Reverse polarity protection
Ground return
What did you observe?
Next safe measurement
Start across the supply rails. Write down the voltage with the project connected.
Open-circuit voltage can look fine while loaded voltage fails.
