Question
How to detect intermittent wiring shorts in EV high-voltage harnesses?
Answer
Use insulation resistance testing and thermal imaging to locate heat-generating short circuits.
Explain
EV HV harness shorts are often intermittent (e.g., only when turning the wheel). CHEPQ thermal cameras detect heat spots (>60℃) at short locations, and insulation testers measure resistance drops during vehicle movement—pinpointing damaged wires under the dashboard or in wheel wells.
