How to Jump Start a Lincoln Corsair

1. Pull back the red rubber boot and attach the positive (+) jumper cable to the positive (+) terminal of the discharged battery.
2. Attach the other end of the positive (+) cable to the positive (+) terminal of the booster vehicle battery.
3. Attach the negative (-) cable to the negative (-) terminal of the booster vehicle battery.
4. Make the last negative (-) connection to an exposed metal part of the disabled engine, away from the battery and fuel injection, or to a ground point.
5. Start the booster vehicle and keep engine speed between 2000 RPM and 3000 RPM, then start the disabled vehicle.
6. Run both engines for three more minutes, then remove the cables in the reverse order of connection.

• Do not connect the negative cable to any other part of your vehicle; use the ground point.
• If you use a jump pack or booster box, follow the manufacturer's instructions.
• Do not switch the headlamps on when disconnecting the cables, as the peak voltage could blow the bulbs.
