Interactive HVJB wiring diagram
Posted: Sun Apr 12, 2026 9:00 pm
Created this wiring diagram for a typical high voltage junction box. Click through the animation or auto-play if on a PC, swipe left and right if on a mobile device. Adds circuits step by step - main HV bus, precharge circuit, charger circuit etc. Build with help from Claude code and is based around my own setup.
