Normally, yes. The positive + post is larger than the negative.
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.
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 negative cable first and reconnect the negative last.
Disconnect the negative cable first.
Connect the positive (+) Red cable from the charger to the positive (+) post of the battery. Now connect the negative (-) Black cable to a metal part of the engine. Do not connect to negative battery post. Plug the charger in. Unplug the charger before removing the cables. Disconnect the negative cable first.
The positive battery cable will be going from the positive terminal of the battery over to the starter solenoid. The negative battery cable goes from the negative battery post to either a bolt on the generator upper bracket or the side of the engine block. Typically, the positive cable is red, and the negative is black, but people do all sorts of odd things to their cars, like have the wrong colored battery cables, so, go by how they are routed, not by what they look like.
Normally the black battery cable is negative.
you hook the positive cable,(usually the red) to the positive battery terminal first then you hook the negative cable(usually black) to the negative terminal if you hook it the other way you can get sparks or arcing that can cause damage or a fire PS: if both cables are same color, the negative cable is the one bolted to the frame or the engine.the poitive is bolted to the solenoid or starter
Make sure that you connected the battery cables properly. The red cable goes to the positive side(+) the negative or black cable to the (-) side.
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.
Red/positive cable to red/positive cable. Black/negative cable to black/negative cable. The battery is under the cover in front of the air cleaner.
Black is negative and Red is positive.
