There are several GM alts that can be converted. Later model units will each need A wiring diagramn. If you are using the '75 and up to the mid '80's alt. It has one large lug on the back that has A nut on it. This is for the charge to the battery, There are two spades side by side on the side near the back. You will need to connect A wire to the one farthest from the battery lug and connect the same wire to the battery lug. The spade that is left will need to go to the extra post on the starter, the one that is NOT for the solinoid wire. I know this sounds confusing, If you can't figure it out after reading it A couple times, Contact me in my message board.
The alternator is not getting power? At any of the wires or just the main/largest one? If you are testing the large wire, this is the output side that runs to the battery. If there is no power in this wire where it connects to the alternator it must have a bad connection at the alternator or at the battery or a break somewhere in between. If there is power there, I would look at the fuses.
Electrical one way valves called diodes often go bad in alternators (part of the regulating system). Other causes would be bad field or stator windings...basically a broken wire somewhere in the alternator. Bad bearings...since the thing spins very fast.
This wire is connected to the solenoid along with a wire going to the power distribution system (Fuse box), but the connection or split is after the fusible link on the wire comming from the alternator. On most vehicles, those connections are attached to the same solenoid bolt. The connection there at the bolt, is done there because the large Positive battery cable also comes to that bolt.
There are two bolts one is visible on the front and one on the rear. There is a nut on the right side next to the ground on the alternator. once it, the ground, and the molex plug are removed it pops right out. One key thing to remember when putting it back on is to be sure to put the belt on before you put the bolts back in, or you have to mess with the tension pulley.
Take off the negative battery cable then the wires on the alt then the bolts that hold it on. First take off the serpentine belt. There should be a schematic of how to reinstall it on the fan shroud. if it is not there you can draw your own before you take it off. Don't rely on memory.
If you have a new alternator its as simple as run the one wire to the solenoid. If you are converting the alternator to a one wire, you will need an external regulator. If you have a new alternator its as simple as run the one wire to the solenoid. If you are converting the alternator to a one wire, you will need an external regulator.
You can tape them off and tuck them away. One wirewas for the idiot light and the other wire was a trigger wire to excite the old alternator.
You remove the belt, unbolt the alternator (2 bolts), disconnect the plug and main wire. Take your new alternator, connect the main wire, plug, bolt it back in the way the old one was, put your belt back on and you're done. 20 min or less
There is 2 bolts on the top that you have to remove, and one underneath, and one electrical plug, and one wire that goes to the starter. Good luck.
There should be one female plug-in and one separate hot wire that is hot anytime the battery is hooked up.
wow, what a precise question. i would do a bit more research on your issue, the alternator for one doesnt control the lights, nor do you ignite an alternator. you should just leave the hood closed and drive it to a shop.
Yes. Instructions come in the box.
This is a dual-field alternator, they both are field connections.

Buy a one wire hook up alternator and route about a 10ga wire from its output terminal to your battery positive or to fuse block, use a piece of fusible link or a circuit breaker rated about the same as your new alternator.
The wiring harness from a typical alternator has three wires. One is for grounding, one is from the battery, and the other is from the voltage regulator. In a GM alternator however, there may be two wires or only one wire. It depends on whether you have an external voltage regulator or not, and if the alternator simply grounds itself to the bracket it's attached to. The best way to find out is to trace the wires to their sources.
Invert Level and Invert Elevation are one in the same. Invert Level = Invert Elevation (IE).
