Alternator Wiring - 5/13/2005 11:50:25 AM

Hello everyone Im new to the formum

I did a search and didn't find an answer.

1969 Mustang small v8... (given to me by my okd man)

The car sat for 3 years and i put a new battery in the car and he had previously put in a new alternator and selnoid.

Finally got the car to start but after 20 minutes running i pulled the neg off the battery and the car shut down.

I looked at the alternator wiring but I have a question. Does anyone have a wiring diagram for how the wired dhould be hooked up because looking at the alterator there is a red/black wire that goes to the altenator to a screw on the left side looking at the alternator from the front. Same angle but right side is a screw that has a RED plastic grommet that is empty. Is the wire that is Black/Red supose to be screw on there or is it right.

I assume that something is wrong because the car went dead after pulling the neg off the battery, so it must be wiring.

Thanks in advance.

Welcome to our section of MF. The negative on your battery is a part of the circuit for the alternator.

Soaring, he should be able to pull off the neg and not kill. Mine wont kill if I pull the neg anyways. I could drive around with no battery, and as long as I dont kill, I would be good.

Here is a page from the 1969 Shop Manuals (worth MORE than the $60 for the FIVE-BOOK SET)



In case your alternator is aftermarket;
I was kind of anal and took pics of stuff before I took it out of my car:

Thank you for the pictures.

The picture in the manual is what I am after i think.

There are 2 screws on the top of the alternator.

1 has a red type grommet inside the screw which nothing is attached to and the other top screw has a black with red strip wire attach to it. Shouldn't this be routed to the other screw as i believe this is shorting out the alternator which means that the battery is being used to run the car. When I remove the neg the car shuts down. Is there any way you can attached a bigger picture that I can see the page 3 better as I can't see the wording or pictures too well even if I download them and try in increase there size. Does the above make sense about the wiring or is this okay to have the black with red stripe attached to the alternator from the front left side.'

Thanks
Michael

Get a manual for your specific year of Mustang. Through the years, and even within specific years, they were all wired differently. Some got the ground from the firewall, and as Mustang 1969 shows it as the blue wire is attached to the solenoid ground on the fender well.
What's up with that southern engineering? And others got the ground from the battery negative terminal. Spend the 40 bucks to get a manual.

Just drove the car home for the first time. It's needs a huge bath, Interior cleaned and the crome polished. Looks to be 100% original. Motor is strong as heck.

By next weekend it will be on here. it's been raining all day.

The diagram I showed was from my 1969 shop manual

And yes, I know my car is jerry-rigged. That's why I have a manual

Thanks Michael

It just so happens there is a sticky at the top where I posted some.

http://www.mustangforums.com/m_518910/tm.htm

Check them out and order some catalogs. Most are free, a couple are under $3.

Scroll down for the link to NPD too

I agree about the wheels. Those look like wheel covers straight from Wal-Mart. Sorry Man, I couldn't help myself. And those tires are slickern' a gut. That would be my first expenditure. Get some Mag 500's and some Goodyear tires.

I totally agree, but that where the tires and covers that came with the car when my dad purchased it back in 1995. Until now Walmart never looked so good

Compounding and repolishing (and replacing) the crome, then the tires are next.What the best stuff to use to repolish the crome? Do you have a good source for keeping the wheel and tires original, so it least you can stop laughing (j/k). That what i did when I saw them to.

Do you want to go concours, and keep the wheels and tires original? If so, just keep the original steel wheels, and try to find hubcaps for a 69. I use the Maguires 3 step cleaner, polish, wax on mine. They also have a chrome cleaner, but just about any chrome cleaner will do the trick. Or, use 0000 steel wool, or Brasso.
