Follow the cables to see where they go, one cable will be fastened to the car chassis, this is your ground wire or the negative post, the other wire should make it's way to the alternator this is your positive cable.
There are typically two cables, one is usually red and the other black. The black cable attaches to the negative terminal on the battery and the red wire connects to the positive terminal on the battery. When removing the battery from the vehicle always remove the negative cable from the battery first. When installing the new battery always connect the negative cable to the battery last.
Red is positive. If they are both black then the cable that is connected to ground is negative and the other cable is positive.
1. Make sure both engines are "off" 2. Red cable on red port of empty battery 3. Red cable on red port of full battery 4. Black cable on black port of full battery 5. Black cable on black port of empty battery 6. Start the car wich has full battery 7. Wait for a minute 8. Start other car (empty one) 9. Remove cables (black first) 10. Drive half an hour to make the battery full again
To jump start a car, first connect the red positive cable to the positive terminal of the dead battery, then connect the other end of the red cable to the positive terminal of the working battery. Next, connect the black negative cable to the negative terminal of the working battery, and finally connect the other end of the black cable to a metal surface on the car with the dead battery, away from the battery. Start the working car and let it run for a few minutes before attempting to start the dead car. The red cable should be connected first.
Connect the red cable to the dead battery's positive post and then connect the other end of the red cable to the good battery's postive post. Then connect one end of the black cable to the negative post of the good battery and the other end to a piece of unpainted metal in the engine compartment of the dead battery's car. Then wait 2-3 minutes and try to start the car.
To safely jump a car when the positive terminal is red, follow these steps: Connect the red (positive) jumper cable to the positive terminal of the dead battery. Connect the other end of the red jumper cable to the positive terminal of the working battery. Connect the black (negative) jumper cable to the negative terminal of the working battery. Connect the other end of the black jumper cable to an unpainted metal surface on the car with the dead battery. Start the working car and let it run for a few minutes. Try starting the car with the dead battery.
Disconnect the cable from the LeSabre battery. Follow the route of the cable and disconnect the other end. Pull the cable out, then fit the new cable in the same direction. Connect the non battery end, then connect to the battery.
It would be essentially the same as connecting a battery in the car, except with longer cables. You would have to use jumper cables to extend the car battery cables. Be sure to follow ALL safety procedures. Do NOT let anyone or anything metal touch anything else except where you make the connections. Do not touch the metal connectors themselves. I assume there is no battery in the car. I will call the battery that is not in the car the "external battery". First connect the positive ("+", usually red) jumper cable to the positive car battery cable, & then the other end of that jumper cable to the positive external battery terminal. Then do the same with the negative ("-", usually black) car battery cable & jumper cable. The last thing you connect should be the far end of the negative jumper cable to the negative terminal of the external battery. When you are ready to disconnect the external battery from these cables, do so in reverse order, starting with disconnecting the negative ("-", usually black) jumper cable from the negative external battery terminal.
Disconnect the positive (+ / red) cable first. Then disconnect the negative (- / black) cable. Do not let one touch metal when other on battery. Take off brackets holding battery and remove. Replace with new battery, put in brackets... attatch cables, negative first, then positive.
Unhook the Caravan cables at the battery. one at a time, follow the cable to the other end, paying attention to the routing. Disconnect the other end, pull the cable out, then route the new cable the same way. Connect the end away from the battery. Repeat for the other cable, then hook back up to the battery.
I assume you're asking how can you tell which is positive and which is negative? The red cable is positive in the black cable is negative. But if they are not color-coded the positive battery post is slightly larger than the negative battery post. If you try to connect the negative cable to the positive post it would be a tight fit and if you connect the positive cable to the negative post it would be loose.
The Negative - Battery Cable will be connected to ground. Ground is the engine block, frame, or other non-electrical part of the vehicle. The other cable is positive. Another way is to connect an ohm meter black test probe to the engine block and touch the red test probe to the cable you think is ground -. If the circuit is complete you have found the negative cable.
