altenator wont charge battery

Most likely its a bad voltage regulator do you have a multimeter to do some testing?

Yes I do I just don't know where that is

Get a meter and we will do some testing.

Okay I have the test light but I just did a t5 swap in it and don't remember if I hooked a ground back up that was connected to a transmission bolt. Is there a ground there?

Not sure if there is one there or not hook the test light to the postive battery cable.Then touch the case of the alternator see if the test light lights brightly.Your really going to need a multimeter so we can figure this out.

I have a multi meter and it says its holding about 12 to 13 volts after putting another ground on it.

So its charging at idle at that voltage?Also if you turn on the headlights blower fan on high etc whats the voltage?That car the voltage should be higher.

The volts will go around 10 when the lights are on

See charging system EWD below-start testing-For me sounds like the IVR @ 10volts lights On and engine running

What is that ivr you are talking about?

He is talking about the internal voltage regulator.Lets see if we have power at the yellow wire with a white stripe and the two black wires with orange stripes at the alternator.Let me know what you find.

What would that be if I'm not getting power to them. I'm at work I get off at and will check when I get home.

If you look at the wire diagram those wires are feed by fusable links so if there wasnt power you woud most likely have a fuseable link blown.Also did you have your old alternator tested out of the car?Did you have your new alternator tested before you left the store?

Now where would the fuses be inside the car where the fuse block is or in the line?

Look at the picture its at the starter relay

Okay thank you I'm going to check it as soon as I get off work.

There fused wires not fuses see if you have power first and we will go from there.

Okay I had to rewire the alternator case the replacement I got was a hard wire type plug. It goes from 2 black with orange stripes into 1 would it be possible if I got them mixed up wouldit not charge?

It shows in the diagram two seperate feeds there both constant power feeds so if the two black with orange stripes were mixed up it should still charge Do you have three power feeds going into the alternator?Do all three wires have battery voltage going to them?

I checked the volts going through the battery and it is 12.53 and I don't have anything but .008 on the casing of the alternator so it must not be getting anything. Idk where the fusible link is but I know where the starter selinoid is. I can't find any wire that goes to the alt. All I see is a yellow one that goes into the inside of the car.

The case of the alternator is ground no power feeds go to it.So you have no wires going to the alternator?If so thats why its not charging.Your supposed to have three power feeds just like the wire diagram rastamaz posted.

Scratch that sorry. I guess I just don't know what wire to pick there is all kinds right there and I just don't know which one it is without ripping them all apart and singling it out.

Did you just buy this car?Your going to have to find the color wires in the diagram that go to the alternator they should be there somewhere.

So I followed the wires and it looks good nothing stands out that would be like a fusible link blown. So where do I go from here?

Bring that alternator back where you got it from and have them load test it.

The diagram that I gave you does the wires matches on the alternator?

Yeah it all is the same and I had them do the load test and it passed.

Do this check for power at the light green and red wire on the alternator-turn ignition On and then check-I'm beginning to get nightmares on this problem-let us know

Okay well I will check it tomorrow morning and find out if its getting any volts how much should it be?

You should have battery voltage at all those wires to the alternator.

OK I will check in the morning and let you guys know.

The only thing that makes sense is you dont have power to one of those wires going to the alternator.

So I am not getting power to that green wire

I only see black with a orange stripe and yellow with a white stripe as power wires to the alternator.Do those wires have power at the alternator?I dont see a green wire in the wire diagram.

OK so I'm getting power to everything there its like the regulator isn't doing its job or something. What does the white with black stripe wire do.

Follow the trouble tree i posted let me knwo what you find.That should lead you to the problem.

I found it and now its fixed the green with red stripe came out of the harness on the back of the gauge cluster. I'm back up and running thank you guys so much

Your welcome thats what were here for glad to hear you got it fixed.

Atta Boy-Your very welcomed-now you can troublshoot the charging system-we stood by your side all the way and we don't intent to quit on you till you fix it-Good Luck

Thank you guys so much man I always got you guys there if I can't figure something out. You guys are my right hand.

Your welcome were here if you need us.
