Installation Guide
Tools Needed:
- Adjustable wrench
- Screwdrivers (flat and Phillips)
- Wire cutters/strippers
- Multimeter
- Safety gloves and goggles
Step-by-Step Installation
- Choose Installation Location: Select a dry, well-ventilated location away from flammable materials and moisture.
- Unpack and Inspect: Remove all packaging materials and inspect the charger for any visible damage.
- Power Connection: Connect to a properly grounded 120V, 60Hz, AC outlet. Ensure circuit can handle the load.
- Battery Connection: Connect red clamp to positive (+) battery terminal and black clamp to negative (-) terminal.
- Charger Setup: Set the charger to appropriate voltage (6V or 12V) based on your battery type.
- Initial Test: Turn on the charger and verify proper operation with indicator lights.
- Safety Check: Ensure all connections are secure and cables are not pinched or damaged.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger won't turn on | Power issue, blown fuse, faulty outlet | Check power supply, test outlet, check fuse |
| Not charging battery | Poor connections, dead battery, wrong settings | Check all connections, test battery, verify settings |
| Overheating during use | Poor ventilation, high ambient temperature | Move to cooler location, ensure proper airflow |
| Error lights flashing | Reverse polarity, battery fault, internal error | Check connections, test battery, reset charger |
| Slow charging | Low input voltage, battery sulfation, small gauge wires | Check voltage supply, use recondition mode, check cables |
| Engine start not working | Battery too dead, poor connections, safety timeout | Charge battery first, clean terminals, wait for reset |
Error Codes & Indicators
- Red Flashing: Reverse polarity detected - Check connections
- Yellow Solid: Charging in progress - Normal operation
- Green Flashing: Maintenance charging - Battery fully charged
- Red/Yellow Alternating: Battery fault - Test battery condition
- All Lights Flashing: Internal error - Contact service center
