toughy v8

can you chaps help me i need to wire my f body alt (the car is not an fbody) but i dont know which wires i need to hook up to im hearing 5v here and resistors there and its getting a bit confusing.

thanks in advance

Should be able to use one wire (brown) for charging, I'd buy the correct pigtail or modify one if you have it already

This link has pretty simple instructions.

Beside the main power out you just need to hook up a single voltage sensing wire preferably through the dash charge light. If you don't have a light available, then use a resistor like shown in the diagram.

I would use the lamp as the resistor so when it charges it will go off.And you know it is charging and if you throw a belt it will come back on.

This is how I did mine as well (with the resistor). No issues.

I would use a 87-92 F body alternator in the bracket you have, it will work, with a bit of thinking and lines up perfect. But thats me.

Any pictures of this set up?
Thanks

I put them on my truck brackets and did test fit a f body bracket with success, but only have pics of the truck setups.

Had a similar ?

I don't have an alternator at all. Was thinking of ordering one of the one wire deals off Ebay. This is a carb fox body. Car doesn't have a light, but does have an autometer volt gauge. Do I still need to use a resistor?

Hey zones throw up a pic of the truck bracket set up

That is the 85 TA, 86 TA then my 94 gmc.

zone what all did you have to do to make it line up? looking to go that route.

Nothing, it just lines up, one side needs the dowel removed,, then a washer or two between the bracket and alternator so there is no stress when the bolt is tightened. Used a newer alternator on the 85 TA, had to grind the bracket a bit, but the 88-92 v8 and 88-95 v8 half ton alternator are best.

Thanks for the help guys. I got my F body Alternator on my car. Got it out of the bone yard and they left the pigtail on it for me. I ran the wire on the pig tail to a light I bought at the parts store and put in the dash, then over to 12v with switch on and it works great.

Just like link above.

thanks fo the help zone

Np, as long as it is a truck or you have a cowl, it is a stupid cheap alternative to a f body or custom setup with a carb.

Good information..I need add 470resistor on ..

Can I run the wire through my stock voltmeter on my 81 camaro? Wouldn't it do the same thing as the charging light?

No .

Hello guys,

I have been trying to figure out this problem i am having on my carbed LQ4.

I have changed the alternator after it stopped charging(probably wrong wiring).
the second alternator is charging fine but it is not compensating for voltage drop.for example, once the engine is running the battery reads close to 14V , but as i turn on various electrical devices(fuel pump, AC, Head lights) voltage decreases close to 9V. and i am sure it affects the perfomance of the MSD box.

I have read many threads and posts on how to wire the alternator, but they are all a bit vague when it comes to model number.

i am using the holley brackets for the CS130D alternator and R4 compressor.

using a pigtail that i cut off an LS harness, using only the two middle wires.
i tried connected a resistor in the circuit just like it shows in some of the schematics linked to this post , but nothing changed.

any suggestions ?
