Inspect damage. Choose an approved repair path. Build a connection, protect the harness, then prove the circuit works under load. A repair isn't complete just because the lamp turns on.

Lesson 1 of 10
02 / Virtual harness repair station
12.6 V • fuse protected • example circuit
Training model: a generic fused 12 V lamp circuit with a 6 Ω load. Wire, fuse and terminal repair specifications are vehicle- and circuit-specific; follow OEM service information on an actual vehicle.
2. MAKE SAFEIsolate power and protect adjacent systems.
3. RESTORERepair conductor / terminal and restore sealing.
4. VERIFYTest under load and re-create the complaint.

03 / Circuit & virtual meter
Tap two test points to place the red and black meter leads, or select them below. Voltage-drop testing is most informative with the load ON; an open conductor is diagnosed by comparing voltage on either side, not by interpreting a zero-current drop.
—Meter reading (DC V)
—Load current
—Voltage across lamp
—Repair-zone drop
Lamp status
No measurements recorded.
04 / Repair quality & decisions
These visual indicators are teaching heuristics, not calibrated crimp-force, strip-length, temperature, or OEM pass/fail specifications.

Decision cues
Inspect the damaged wire, identify the circuit and check the applicable service procedure before choosing a repair.
Safety boundary: Do not apply general low-voltage splicing methods to orange high-voltage wiring, SRS/airbag wiring, or other restricted circuits. Follow manufacturer procedures and required qualifications; a complete harness or component replacement may be required. Never bypass a fuse or perform live ohmmeter testing.
05 / The Challenger's repair missions
0 of 5 verified
Choose a mission, inspect the concern, configure the repair, restore the circuit and verify it under the original complaint conditions. Each mission uses the same lab above.
Load a mission to begin.
06 / Final knowledge check
Answer all six questions. A score of 5/6 or higher passes; retry as often as needed.
