- Attach the other red clamp to the positive terminal on the jumper starter.
- Connect the black clamp to the negative terminal on the jumper starter.
- Attach the other black clamp to a metal ground on the vehicle with the dead battery, away from the battery itself.
Avoiding Common Connection Mistakes
Incorrect connections can cause sparks or damage the battery. Avoid these common mistakes to keep the process safe.
| Mistake | Why It Is Dangerous | How to Avoid |
|---|---|---|
| Reversing positive and negative clamps | Can cause sparks and battery damage | Check terminal signs and colors before attaching |
| Connecting black clamp to battery terminal | May cause sparks near the battery | Attach black clamp to metal ground on the car frame |
| Not securing clamps tightly | Loose connection can interrupt power flow | Ensure clamps are firmly attached to terminals |
