A Toyota alternator is essential: It produces a constant supply of electricity while the car engine is running and powers all of the electrical items in your car. Additionally, it charges your car's battery. The design of a Toyota alternator is similar to that of any other alternator, but Toyota models are made specifically for operating in a Toyota, as the output from the alternator is matched to the electrical requirements of your car. Wiring an alternator is moderately simple, although car manufacturers, Toyota included, often locate them in places that are difficult to access.

Difficulty:
Moderately Easy

Instructions

things you'll need:

  • Protective gloves
  • Goggles
  • Wrench
  • Screwdriver
    • 1

      Put on protective gloves and goggles before attempting to wire your Toyota alternator. Open and secure your car hood. Disconnect the black negative battery cable from the car battery using a wrench so the electrical power is isolated. Disconnect the red positive battery cable using a wrench, then move the cables safely away from the battery terminals.

      Locate the two positive and negative terminals on your Toyota alternator. They're clearly labeled "--" and "+" or colored red and black. If there's a third terminal, it connects to your dashboard warning system. The third terminal is smaller than the other two.

      Loosen the terminal connectors on the alternator with a screwdriver or wrench, depending on the type of connection. Don't undo them completely, unless the cables used to connect to the terminals have eyelets. If you do need to remove them, do it carefully --- they can easily fall out and get lost in the engine compartment.

      Locate the cables that attach to your alternator. They're nearby and colored red and black. The red cable extends from a wire loom, while the black cable is attached to a metal part of your Toyota. If there's a third wire, it's usually colored yellow or blue and is much thinner than the other two cables.

      Attach the positive red cable to the positive terminal on the alternator. Either slide the wire under the connector or place the eyelet over the terminal. Tighten the connector using a wrench or screwdriver.

      Attach the negative black cable to the negative terminal on the alternator. Either slide the wire under the connector or place the eyelet over the terminal. Tighten the connector using a wrench or screwdriver. If there's a third wire, attach it to the third terminal of the alternator using the same method. Check that the cables are secure.
