Replace the Alternator.\015\012Sounds like the internal brushes have worn out as you appear to have the correct feeds to it.\015\012If you are tempted to open the alt to have a look at the brushes, be careful as incorrect assembly can cause serious damage as can incorrect re-assembly. You can simply replace the brushes but I would advise against it as the copper rings the brushes rub on (the slip rings) will also be worn and require replacement, this is difficult if you do not have the experience. Also, the bearings should also be replaced as they will no doubt be worn too. Altogether a specialist job, so grab yourself an new or exchange alternator. if you have to get a second hand unit, have it tested BEFORE you fit it..

Im having a voltage regulator problem on my 96 ford explorer(V8 XLT). I've replace my alternator twice already and the same problem is occurring, voltage regulator failed. Obviously it's draining my battery. When I'm driving, the battery gauge bounces, then stays steady at a low position, then all of a sudden it jumps back up. I've inspected the wires and they seem fine, I've also had the alternator tested before I purchased it and it passed, the battery is brand new and i also replaced the star

I purchased an alternator from e bay advertised as late model gm. it looks like gm but has no screw on the back to attach ahe battery wire. it has a connector with three large pins in it. the other connector has three smaller pins in it. what could it fit? it appears to be a 75 amp alternator


From what you are describing, it sounds very similar to a late model ford alternator that were made through the 90's, and it sounds like the type that ford used in the F-350's and larger trucks. ... 1986 Chevrolet Chevy

Charging system replaced both alternator and battery. Checked belts, fuses ect. No voltage coming from the alternator. Took it off and had it tested. It came back good. My question is this: on the pig tail that plugs into the alt. there are three wires, one I assume is a ground, one has voltage going into the alt. what is the third wire for and could that be the problem

What do the wires in the plug on the back of the alternator on a 1992 nissan pick up do? I know that the larger wire is positive to the battery, but wondering what the other wires do? Alternator bench tested good, but on the truck its not charging. Is the voltage regulator external or internal?

Use a jumper to connect the positive terminal of the battery to the terminal L input of the alternator. That will give 12V to the exciter circuit of the voltage regulator and turn on the alternator so that it can begin charging. If that makes a dif ... 1997 Buick Riviera

1995 jeep grand cherokee electrical problem. checked wires to starter. theyre good. the battery is grounded good. have voltage to fuse panel. i was checking continuity by hooking a wire to the negative terminal and checking the switch plug on the back of the heater control panel. had continuity. then i switched to positive terminal. i had continuity. this' to me means there is a short somewhere, but it is affecting the window and lock controls also. is there an easy way to trace a short. thanks,


It depends on how you were checking continuity.\015\012If you are using an ohmmeter (which is only $3 at Harbor Freight), then the question is what resistance reading do you get?\015\012The positive is continuous with the ground, through ... Jeep Grand Cherokee

My car would shake when at a stop and almost turn off. The belts would make an awful noise. I took it into the shop and they changed my spark plugs and the connector wires, and they replaced all three of my belts. One the drive home the car did the same exact thing but worse, it wouldn't let me go over 25 miles and the light started to blink. I took it back in and they said it was my alternator and battery, both got replaced and now the light is back on. Don't really want to push the gas too muc

Yes, the voltage regulator is internal to the alternator, however pulling off the battery cable while the engine is running is not a valid, proper, or orthodox procedure or test, and when you dis-connect the battery while the engine is running the vo ... 1976 Cadillac Deville

I just finished rebuilding my truck engine and will like to test it before installing back in the truck. I know how to get the starter going, but I don't know how to wire the coil, distributor, alternator etc. It is a 1971 360 engine 5.9l . The engine is already set up completely with the alternator and radiator. I just don't know if I just put the positive wire from the battery to the positive on the coil. Or a wire from alternator to the coil???, any help is welcome. thanks

I'm wiring two 12volt lights to 12 volt battery controlled by a illuminated 12 volt rocker switch with 3 terminals. I have both lights connected wired parallel to a terminal block. I then run one lead to the positive terminal of the battery with the other lead running to the switch and back to the negative terminal. That controlled the light, but how do I get the switch to illuminate. Please note I'm not familiar with electronic terms. Please use laymen terms

Part 2 Positive Battery Terminal Wire corroded off. Can I just replace the connector? Why is there 3 wire going into the positive connector. cannot find a replacement connector.


OK, we'll start with thesecond question. The reason you have three wires going into the positive connector is because you NEED three of them for everything to work. The largest of the three wires goes to the starter motor. You need this large wire ... 2003 Land Rover Freelander

I have a 2000 ram 2500 with diesel. The alternator does not have any voltage on the blue wire for postitive excitation. The green wire (negative) will read to battery + so it is okay. I have done a continuity check of both of these wires back to the plug on the PCM and they are good. I do not have voltage on C3 pin 25 with the key on. Are there other parameters in the PCM that would keep it from outputting the exicitation voltage? Can you suggest any thing else I can do?


The green wire should be your gen field wire not a ground wire. The alternator should be grounded through the alternator. The blue wire should be a feedback to the pcm only when the alternator is charging (engine running). Make sure your main 140amp ... Dodge Cars & Trucks
