Electrical Issues: Short Circuits Explained

Your car's horn honking when you hit the brakes isn't a ghost, it's a short circuit.

This happens when two unrelated wires touch, creating a "crossed circuit."

All car electrical problems are one of three things: a short like this, an "open" where

a wire is broken and something just stops working, or "high resistance" from corrosion,

making your lights dim. Technicians trace these gremlins using wiring diagrams

and a multimeter. A simple voltage drop test can pinpoint that one bad connection causing all your

headaches. It’s not magic, it’s just electricity taking a wrong turn.
