Fans or other mowing engine park can injure you badly. Keep your hands away from moving parts once the engine is running. 5. Check that the jumper cables don't have loose or missing insulation. If they do, you could get a shock. The vehicles could be damaged too. 6. Connect the red positive (+) cable to the positive (+) terminal of the dead battery. Use a remote positive (+) terminal if the vehicle has one. Before you connect the cables, here are some basic things you should know. Positive (+) will go to positive (+) or to a remote positive (+) terminal if the vehicle has one. Negative (-) will go to a heavy, unpainted metal engine part or to a remote negative (-) terminal if the vehicle has one. Don't connect positive (+) to negative (-) or you'll get a short that would damage the battery and maybe other parts too. And don't connect the negative(-) cable to the negative (-) terminal on the dead battery because this can cause sparks. 7. Don't let the other end touch metal. Connect it to the positive (+) terminal o the good f battery. Use a remote positive (+) terminal if the vehicle has one. 5-49
