Main fuses and fusible links: VW typically has high-amp fuses near the battery and under the dash. Even if they look okay visually, test with a multimeter.
Grounds: Inspect and clean all major grounds (frame, engine, battery strap).
Alternator: Reverse polarity often kills the alternator’s rectifier diodes.
