A floor scrubber charger "not charging" usually indicates a combination of six faults. Follow the three steps of "look → test → replace" to quickly pinpoint the problem: I. Overview of the Six Faults | Fault | Symptom | Quick Diagnosis | | 1. No mains power | Indicator light off | Change socket → Light on → OK | 2. Blown fuse | Indicator light off, multimeter no 300V | Multimeter input → No power → Replace fuse | 3. Broken output wire | Light on but no output | Multimeter output → 0V → Replace wire | 4. Reverse battery connection/short circuit | Light flashing or 0V | Replace with same model battery → Normal → Battery faulty | 5. Bulging capacitor | Light on but low output | Multimeter ESR > 0.1Ω → Replace capacitor | 6. MOSFET short circuit | Light on but short circuit | Mult...
