An alternator is an electromechanical device that converts mechanical energy into electrical energy. An alternator is so named because it produces alternating electrical current. This energy can be converted from one voltage to another using a transformer. Thus, the 12-volt AC output from an alternator can be transformed into 120 volt-AC current.

    Cut four lengths of wire. Strip ½ inch of insulation from the ends of each wire.

    Attach one end of the first wire to one of the transformer's primary winding terminals and solder the wire to the terminal. Attach one end of the second wire to the remaining transformer's primary winding terminal and solder the wire to the terminal.

    Attach one end of the third wire to one of the transformer's secondary winding terminals and solder the wire to the terminal. Attach one end of the fourth wire to the remaining transformer's secondary winding terminal and solder the wire to the terminal.

    Slip a ring terminal over the free end of the third wire and solder the terminal to the wire. Slip the remaining ring terminal over the free end of the fourth wire and solder the terminal to the wire.

    Attach the free end of the first wire to one of the alternator output terminals and solder the wire to the terminal. Attach the free end of the second wire to the remaining alternator output terminal and solder the wire to the terminal.
