Jump starting a car:
I suggest carrying around a good set of jumper cables. Good ones have real heavy clamps and are at least 6 gauge wire 4 gauge wire is better (lower gauge is thicker wire).
- Move the running vehicle so that it's battery is as close to dead battery in the other vehicle as possible
- Leave the vehicle with the good battery running
- Make sure all accessories (lights, radio, etc.) are off in the vehicle with the dead battery
- connect the red cable to the red (+) terminal on the vehicle with the dead battery
- Connect the other end of the red cable to the red (+) terminal on the running vehicle
- Connect the black cable to the black (-) terminal on the vehicle with the dead battery
- Connect the other end of the black cable to the black (-) terminal on the running vehicle
- Do not attempt to start the vehicle with the dead battery yet, it probably won't start and if you do try it will only take longer.
- Go sit in the running vehicle for a few minutes. I suggest bringing the engine up to a faster idle (1500 RPM) so it will charge the dead battery faster. To do this just lightly press on the gas pedal, you will hear the engine speed up some
- After 5 or so minutes have someone else go and try to start the vehicle with the dead batter. Keep the running vehicle at the faster idle.
- If the vehicle with the dead battery started continue to step15
- If the vehicle with the dead battery turned over (tried to start) but didn't start go to step 9
- If the vehicle with the dead battery didn't turn over go to step 9 but let it charge for 10 minutes
- If you get here and have tried starting the other vehicle and it won't start the battery is probably totally dead so go get a new one, or the starter is the problem and go get a new one. Continue to step 15 and disconnect the jumper cables.
- Disconnect the black cable from the car that has been running the whole time
- Disconnect the black cable from the car that got the jump
- Disconnect the red cable from the car that has been running the whole time
- Disconnect the red cable from the car that got the jump
- If the car that got the jump is now running have them take it for a drive for at least 30 minutes to get the battery charged back up. Highway driving is better as that is at a constant speed and will charge the battery quicker and will put less of a load on the battery. You can end now
- If the char that got the jump isn't running check the battery and starter. (This will be discussed in another post later)
- Do NOT have the battery charger plugged into the wall
- Connect the red cable to the red terminal (+) on the battery
- Connect the black cable to the black terminal (-) on the battery
- Plug in the battery charger
- Select the type of charging. Some chargers don't give you an option, these are trickle chargers. The various options are below
- Trickle charge (1-2 amps) This is the best way to charge a char battery, use it if getting the vehicle started can wait several hours (overnight)
- Quick charge (5-20 amps) This is used to quickly charge a battery, expect to let it charge for several minutes (10-30 depending on battery size and output of charger)
- Start (50-200 amps) This is used to start a vehicle. You should still let charger charge the battery for a few minutes (5 is probably plenty). This is really hard on batteries
- Let the vehicle charge
- Unplug your charger
- Disconnect the black cable from your battery
- Disconnect the red cable from your battery
