There is a part that connects to the positive side of the battery. It is black and it has a ring that attaches to the battery. On the back end of the connector it plugs into another connector which has green and red wires. The ring which connects to the battery broke. Please advise what the name of the part is.

Use a wrench to remove the negative and positive battery cables: They are clearly labeled "+" and "-." Always remove the negative cable first, as this isolates the power to the metal parts of your car. Tuck the cables away from the battery as you don't want them to accidentally touch a battery terminal when you're wiring your alternator.

Locate the alternator terminals. There are two: one marked "live," "pos" or "+" and the other marked "neg," "field" or "-."

Locate the two cables. The positive (red) cable goes to your battery via a wire loom or harness. The negative (black) cable attaches to a metal part of your car.

Check how the cables attach to the alternator terminals. Some connect using eyelets that hook over the terminal and tighten with a bolt; others connect by inserting the wire under the terminal and tightening a bolt.

Loosen the two bolts using a suitable-sized wrench or, if the cables connect using eyelets, remove the bolts.

Insert the exposed end of the negative (black) cable under the loosened bolt on the negative terminal of the alternator, then tighten the bolt. If the cable has an eyelet, hook it over the terminal and screw the bolt back in place and tighten using a wrench.

Insert the exposed end of the positive (red) cable under the loosened bolt on the positive terminal of the alternator, then tighten the bolt. If the cable has an eyelet, hook it over the terminal and screw the bolt back in place and tighten using a wrench.

Replace the positive battery cable on the positive battery terminal using a wrench. Replace the negative battery cable on the negative battery terminal.
