🧠 Electrician rules of thumb
🔋 No voltage at source → battery dead
📏 Voltage lost → cable/terminal oxidized
⚡ Fuse dies instantly → short on bare wire
🔩 Ground must read 0 V — 1.8 V = bolt rusts
💡 Voltage there, no light → lamp itself blown
🪫 Rest voltage ok, load sags → battery high-ohm
⚠️ Learning tool. For real work: disconnect battery, check insulation, call Kfz for airbag/hybrid!
