How do the wires hook up on an alternator?

Typically, the alternator has three connections. One is the ground, which is provided by the bracket that you bolt the alternator to. Second is the main power terminal, and is connected with a bolt to a high power cable that goes directly to the battery. CAUTION: Make sure you disconnect battery ground before you put a wrench on the alternator stud, just in case you touch ground while turning the wrench. Third is a two or three pin connector that goes to the harness, providing regulator power and connection to the warning light. Some older alternators have an external regulator, and they will have a smaller bolted connection to the regulator. Its easy to see which is which, due to the terminal size.

How do you replace the alternator assembly?

It would help to know the year, make, model, and engine size as most cars take different routes to remove and replace

( r & r) an alternator. First, you need to know if the bolts and nuts are standard or metric so as to supply yourself with the proper tools. Even before that you can take the car to Wal-Mart or other light repair shops in your area to have the battery and alternator diagnosed before you start the r&r of the alternator. Even some auto parts stores will test the charging system for free. That is the very first place one would start, unless you know as a fact the alternator is bad. After the tools, you must remove either the negative battery cable or the positive battery cable. That is why the year, etc. of the vehicle is important. Then remove all the wires attached to the alternator. One should be a plug in and the other will have a nut attaching other wires to it. Next, the alternator belt has to come off. This is either a single, specific belt or a serpentine belt that attaches all the vehicles accessories. If it is the serpentine type you only have to loosen the belt just enough to slip the belt off the alternator pully. There is a large nut which is on a idler pully. This is what keeps the serpentine belt tight. The idler pully is a spring loaded pully that is smooth with no teeth. It is slick and chrome looking. It is mostly found at the top of the serpentine belt assembly in just about every vehicle. Then you will loosen the two or three bolts/nuts holding the alternator to the mounting bracket. Replace the old alternator with the new one and reverse the sequence of events. I would still like to know the 411 I asked in the first sentence. That way I could do a better job of guiding you through this process. Also, buy some gloves, the kind doctors wear. It will really save your hands. Believe me, I know.

Hope I helped, Robert.
