Ensure the charger's power switch (if present) is in the OFF position. If your model has voltage selection (6V/12V), set it to 12V.

The most critical instruction is the Voltage Selector Switch . Leaving the switch on 24V while charging a 12V car battery will boil the battery, cause it to swell, and potentially explode. Always double-check the selector position before powering the unit.

The Selmar Turbo 4 battery charger is a testament to an era when battery charging equipment was built to last. Its simple, robust design has kept many a classic car and caravan battery in service for decades. By following the instructions in this guide—particularly the crucial safety precautions—you can safely and effectively use your Selmar Turbo 4 to maintain and recharge lead-acid batteries.

| Symptom | Probable Cause | Solution | | :--- | :--- | :--- | | | 1. Blown mains fuse. 2. Poor connection at battery terminals. 3. Internal thermal cutout tripped. | 1. Check wall socket and replace fuse. 2. Clean battery posts and tighten clamps. 3. Let charger cool down; press reset button if available. | | Ammeter needle goes backwards | Reverse polarity connection. | Stop immediately. The battery is connected backward (Red to Negative). Swap the clamps. | | Charger hums loudly / vibrates | Transformer laminates loose or internal short. | Stop use. This indicates an internal hardware failure. Service by a qualified technician is required. | | Clamps spark on connection | Battery voltage very low (dead short) or connecting to highly volatile terminals. | Ensure the charger switch is set to "OFF" or "0" before connecting. | | Battery won't hold charge | Sulfation or dead cell. | The Turbo 4 can sometimes recover sulfated batteries by charging at a low rate (Position 1) for 24 hours. If it still fails, the battery is likely dead. |

It is highly recommended to disconnect the battery from the vehicle to avoid potential damage to the alternator.
