The large wire is the "hot" output that goes to the larger lug on the backside of the alternator...be sure to remove the ground battery cable before attempting any repairs/replacement of the electrical system as to not cause a short...the other smaller diameter wires should be self explanetary, they are usually inserted into a plug which fastens to the side or rear of the alternator....that unit is called a "Delcotron Alternator" which has an internal voltage regulator built into it, refere to this type of alternator when replacing the unit.

Disconnected wireing


You need to keep the wires apart or they will arc, so be careful. They will hook into the back of the alternator, but you need to know which post they go to. An auto parts store with a replacement alternator that fits that car will be able to tell you which post will take the red wire and which one takes the black one.

I have a 97 gmc jimmy,ive replaced the alternator twice,it starts to squeal and alternator will get very hot after 5 minutes,squeal stops if i unplug connector and ive checked it for a short with a test...


The post on the back of the alternator should`read 14 volts when running. You should get very close to the same reading at the battery posts (when the rear alternator post is hooked up to the harness).If you get any significantly different reading at either location, disconnect the harness from the back of the alternator and run a 4 gauge wire from the alternator to the positive post of the battery and see if you still have a 'hot'. noisy alternator. My guess is that the wiring in the harness is shorted somewhere.

Not getting charge out of alternator and it is good alternator wiring seems to be in good shape what else could cause problem relays how can you tell if good


If you're not reading a charge(13+ volts)at the battery, but you have voltage output from the alternator. There are 2 fuseable links, 1 is in line with the red battery wire from the stud on the
alternator to the starter. This link can be bypassed by running a wire from the alt. stud to the pos+
post on the battery. The other fusable link is in line with the red stator wire from the regulator plug.
Check these links and repair or replace if needed. Hope this helps.

Need a picture or schematic of battery to alternator wiring on a 1982 southwind motorhome with a 454 chevrolet engine


I can't give you a schematic but i can tell you where the wires should go;Battery post of the alternator should go to the center post of the battery splitter box that splits between the engine and the house.In the alternator plug the wire closest to the battery post of the alternator needs to go to the charge light or an ignition source.The other pin in the plug can just be looped the the battery post of the alternator.If you have no power to the alternator but do have power to the box that splits the power from vehicle to house the you need to put all the wires on the post marked batt until you can get a new one,this should get you up and running.If you are planing to remain camping with the temporary repairs made then separate the wires until you are ready to start the camper to prevent a dead battery condition if the house battery gets run down.Hope this helps.

Wiring the engine compartment on my 1973 firebird with built in regulator on my alternator witch wires go to alternator then to starter to keep the battery system charching ? the system is not charching...


the wire will go from the post on the alternator the one with the nut to the hot post on the starter then another cable will go from the starter on the same post to the positive on the battery. however if the car died tells me something else is not right because the vehicle doesnt run off of the battery it is merely to start it then the alternator feeds the power while running. you should be able to remove the battery while running and should still keep running

How do I know If my alternator is going out on my 1997 Buick Park


while your engine is running take the positive post loose on your battery .. If the car keeps running then the alternator is ok .. if it dies your alternator is not working .. Should be an easy change on that model it has a belt hooked to it and one large red wire and a plugin with two wires to this ..

88 s10 wiring problem


if you have a 4.3 liter the wire from the positive post on the battery should go to starter and to the post with 10mm nut on the back of the alternator with a 2nd wire that goes to your ignition coil. ignition coil wire should have a fusible link in the line.
