Installation Guide
Tools Needed:
- Safety glasses
- Adjustable wrench
- Wire brush
- Voltmeter (optional)
- Clean cloth
Step-by-Step Installation
- Choose Safe Location: Select a well-ventilated area away from sparks, flames, and combustible materials.
- Prepare Battery: Clean battery terminals with wire brush to ensure good connection. Remove any corrosion.
- Check Battery Voltage: Verify battery is 6V or 12V. Do not attempt to charge 24V batteries or other incompatible types.
- Connect Charger: Connect RED clamp to POSITIVE (+) terminal first. Connect BLACK clamp to NEGATIVE (-) terminal or grounded metal away from battery.
- Power Connection: Plug charger into grounded 120V AC outlet. Do not use extension cords.
- Select Voltage: Choose 6V or 12V setting based on your battery type. For automatic models, charger will detect voltage.
- Monitor Charging: Observe charging process. Most models will automatically switch to maintenance mode when fully charged.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger won't turn on | No power, faulty outlet, internal fuse | Check power supply, test outlet, check/replace internal fuse |
| Not charging battery | Poor connection, dead battery, wrong setting | Clean terminals, verify battery condition, select correct voltage |
| Charger shuts off quickly | Overheating, battery defect, short circuit | Allow to cool, check battery for shorts, ensure proper ventilation |
| Error code displayed | Reverse polarity, bad battery, voltage mismatch | Check connections, test battery voltage, verify 6V/12V setting |
| Slow charging | Low input voltage, long extension cord, battery size | Check household voltage, avoid extension cords, use higher amp setting |
| Spark when connecting | Charger turned on, battery load, incorrect sequence | Always connect with charger off, connect positive first |
Error Codes
- E1: Reverse polarity - Check clamp connections
- E2: Battery voltage too low - Battery may be defective
- E3: Battery voltage too high - Check battery type
- E4: Charger overheating - Allow to cool, improve ventilation
- E5: Output shorted - Check cables and connections
- E6: Input voltage problem - Check AC power source
