When connecting wire to a battery, it will be necessary to remove some of the wire insulation using sandpaper before connecting it. Why do we do this?

Installing a car battery is a simple task that can be performed by anyone who is strong enough to lift the battery into place. Car batteries generally weigh around 40 pounds, depending on battery size. Installing your own battery can save you both time and money. Though many places offer free battery installation when you buy from their in-stock selection, the process is not always quicker than simply doing it yourself.
You’ll need a new battery, combination wrench, flat screwdriver and wire brush or steel wool.
Turn the engine off and pop the hood. Find your battery and the two battery cables attached to the battery. One cable is red and the other cable is black.
Use the combination wrench to loosen the nuts holding the battery cables. If your cables do not indicate which is positive and which is negative, consider marking them in some way so that you can distinguish them.
Remove the battery clamp.
With both hands, lift up on the handle attached to the battery. Be careful because the battery is very heavy, and you do not want to damage your car or hurt yourself.
Clean out the battery tray. Use the wire brush or steel wool to clean any corrosion off of the metal clamps that attach to the battery terminals. If they are badly corroded, you'll need to have them replaced.
Place the new battery into the tray and reattach the battery clamps and both battery cables.
Reattach the cables to the new battery. Remember that the cables are color-coordinated. Attach the red cable to the positive terminal and the black cable to the negative terminal, and tighten the nuts. The nuts are tight enough when the cables cannot move if you try to wiggle them by hand.
Take the old battery back to where you bought the new battery for proper disposal.
Tips:
Keep up with your battery’s warranty information in case your battery doesn’t last as long as it should.
Most places charge what is called a “core charge” when you buy a new battery. Since batteries contain lead, they must be disposed of properly. Simply keep your receipt and return your old battery to the store where you bought the new one to get the core charge refunded to you.
Clamps that attach to battery terminals are usually ½ inch, so try a ½ inch combination wrench first.
Be careful to keep from getting any battery acid on you or on your clothes. Car batteries contain sulfuric acid which can cause severe burns and can damage your clothes.

lacking insulation on the floor cord won't reason a issue with the alternator. Many older automobiles, autos and tractors used a floor "strap" that became right into a braided cable without insulation to start with. in case you have a foul connection between the battery and the physique or the engine block then sure, that would desire to keep away from it from charging. On some automobiles the battery is grounded to the physique and there's a separate cable from the physique to the engine. If this cable between the engine and physique is broke or lacking it is going to reason each form of electric powered issues.

First, removing the insulation makes for better contact.
Second, Oxidization happens when a wire sits for a long time. It's like rust.

you need to remove the insulation of the wire since you need to have a proper contact between the nickle-copper wire to the terminals of the battery

Because the insulation keeps power from flowing and we want power to flow when we use the battery
