Practise electrical troubleshooting with realistic faults, virtual tools, and guided diagnostics in DC Electrical Diagnostics.
Safety included with every paid plan.
Practical electrical training requires repetition, but lab time, equipment availability, and instructor capacity are limited. TradeRig gives learners a safe place to practise before working on physical systems.
Apprentices need to run faults again and again. A shared bay can't give everyone the time.
Training rigs are expensive and often in use. Equipment access becomes the bottleneck.
A wrong probe or a reversed connection on a live harness can damage components and add cost.
Instructors have little insight into who understands diagnosis until it shows up on the job.
The same diagnostic loop a technician follows, practised safely in the browser.
Drag components onto the canvas and wire up a 12V/24V circuit.
Inject a fault (open, short, bad ground, blown fuse) or let a scenario surprise you.
Probe with a virtual multimeter and test light.
Follow the evidence to the root cause.
Make the repair, run it again, confirm it works.
DC Electrical Diagnostics, with Safety fundamentals included in every paid plan.
Build circuits, inject faults, and trace them with real test tools: relays, grounds, loads, fuses, and voltage drop across live systems.
LiveLockout / tagout, PPE, and hazard recognition. The safety fundamentals behind sound electrical work. Included with every paid plan.
IncludedA full toolkit around the canvas, giving learners the tools and feedback they need to diagnose with confidence.
Batteries, fuses, relays, loads, and more.
Open circuits, shorts, bad grounds, blown fuses.
Probe voltage, continuity, and current. Blow the fuse if you measure amps wrong.
Live hints and guidance as you work.
Clear steps to follow, plus open challenges.
Scores, attempts, and skill insights.
Every run saved and reviewable.
Practise realistic circuit behaviour and build confidence before working on live systems.
Keep your diagnostic skills sharp between real faults, when the equipment you service rarely breaks.
Learn how DC circuits behave and how to test them safely before you touch real wiring.
