Alternator and wiring problems

Hi and thanks for using 2CarPros.

I have no idea what that is on the dash. I pray it isn't anything from the alternator. However, wires do run into the vehicle. I attached a wiring schematic for you to look at. It is the entire charging system. I had to break it into two pictures because of size and so you can read it. Take a look at it. It shows wire color, where they go, and indicates everything related to the charging system.

Here are a few links that you may find helpful:

Take a look through the schematics I attached and see if it helps. Let me know if you have questions or need help. Also, I would love to know what the wires sticking from the dash are for.

Take care,

The wiring on this car in general is just a mystery. they bypassed the key starter to put a starter button in. I turn the key and push a button to start the car. there is a switch to turn on radiator fan that never worked. Only thing i can think of for that ground on top of the dash was he had a phone charger bolted by it but no wires to it so i didn't understand. The schematics definitely make more sense. i am going to try tomorrow morning redue it.

Should i just replace the serpentine belt to while it is off?

Welcome back:

If the belt has cracks or looks dried out, I would. If it is in good condition, I would reuse it.

I'm glad they are helpful. Please make sure the battery is disconnected before you work on the wiring and alternator. Also, let me know if I can help. It sounds like you have your hands full.

Take care,

So problem i am running into is just getting the part out. i think the brake booster has been replaced. i cannot get it out on top or even out from the bottom.

I finally got new part in and everything seems working good. The wire coming out of the dash is spliced into the ground wire for the alternator from what i can see all the rest of the wiring is done correctly.

Welcome back:

Good job. I'm glad you got it working. I still can't understand the ground wire coming out of the dash. Regardless, let me know if you need anything.

Take care,

Car works fine now only thing is the engine will surge every now and then sounds like it will shut off. Would that be air control problem or fuel pump thing?

Hi Kitty and welcome back.

I hate to do this, but I have to ask you to repost the new question on a new thread. We are trying to keep all threads focused on one problem at a time.

Please do that and I will watch for it and reply.

Take care,

So i went to yank out the mystery ground in my car dash. when i ripped it out now the entire car wont start or click over.

Wow. Do this. Tell me approximately where it is going and the color of the wire. I will look through schematics and see if I can locate it.

Let me know.

Joe
