How To Change An Alternator

Disconnect the Wires

Now that you’ve found the alternator, don your gloves and get to work. Depending on the type of vehicle and alternator you have, there may be one or several wires attached to the device. Using the proper sized wrench, remove the wire or wires from the back of the alternator. It may be helpful to label the wires as you disconnect them if you are worried about getting them back in the correct order later.
