I believe i have a one wire alternator. is it just an actual one wire to the battery? or do i have to do something with the second post?

the picture is rotated clockwise, sorry!
i currently have a wire hooked up to the bigger post straight to my battery

 

that's an old '60s delco alternator-its meant to use a
seperate voltage regulator-old skool electro mechanical
one...

 

wow, lol looks like you need a si or cs

 

What is a Si or a Cs? What alternator should I get? Anyone have a part number or something?

 

Depending on what accessories you are running will determine the amp watt size you will want to go with. I would go to the parts store and ask for a alternator say 76 camaro with a 350. from the mid 70 to around 84 or so the 10 si was used in cars and trucks. just connect the red wire to the output post and the white wire would go to he idiot light if you have one or want too hook it up.
you can use a plug like this and wire it into a 1 wire.

ok so just go in and ask for a 76 camaro with a 350 alternator?

 

yup, if you need more amps ask for one for a truck or a car with a/c or power windows. the 10si ones ore cheap, but will will have to proabaly have to eat the core charge or bring back this one later and they may not notice its a old external regulator one.

 

Ok thanks for the help! I have no dummy light or anything, so I just hook up the one wire?

 

The output post will go to the horn relay or the starter or directly to the battery. Your other connection will be from the regulator to the output post. Do a search do 10si schmatic or wiring

 

The regulator is internal, correct?

 

yes, post 2 on the si is the trigger.

So you just basically connect them both to the same positive battery terminal?

 

post 2 of the alternator to the the alternator output stud. Than a wire from the output to the battery. depending on the amp output decide the gauge to run. I would use a 6 or larger. you can reclock this alternator if needed.

 

Wow 6? Good thing, I was gunna go with ten.

 

i have installed many of the one wire delco alternators. all you have to do is rev the engine above 1000 rpm and it will start charging.

 

Mine looks like this on the back.

It's still the wrong one?

 

yours in the pic is a dn series external regulator. If you need to reclock a 10 si it is easy just take out the four casing bolts and turn it just don't pull it back or you will need to install a paper clip to retain the brushes to reassemble.

 

Ok. Why would I have to reclock it?
Yea I guess mine sorta looks right but it's not, you guys are the gurus!

I was thrown off by whatever those plugs are in the middle.

 

you would might need to reclock a si if the plug is not accessible. looks like you will need a shorter belt too. were did the stock alternator go? if this thing is fuel injected you need at least a 100amp.

 

It's carbed. I do need a shorter belt. I got a smaller water pump pulley then what was original, so the alternator is way over. This is the alternator that was with the motor in the last vehicle.

 

got ya, the fuel lines in the picture were throwing me off.

 

i just got this alternator, will it work?



the correct way to hook it up?

 

yes that is a 10si it will work, looks like its clocked ok that the terminals will be out of the way. Large post to the battery, number 2 to the fan relay there should be a brown wire originally going to the alternator. number 1 would go to the mil lamp through a resister if you chose to hook that up. Number 2 is a switched power to excite the alternator. If you want a true 1 wire you can install a low tun on exciter.

I got that plug form autozone 3 bucks off the shelf in the electrical isle.

 

Well I'm doing it as minimal as possible. The car has no wires left in it . So basically power to battery. Someone told me to jump the 2 post to the power post?

 

Here is the new one. It looks like its charging!

 

 

I have an alternator from a 96 chevy truck it's a single wire plug with it. My original is a two wire plug. What would I have to do to get it to work on my car.

1991 Camaro with an 88 350 tbi converted to carbed.

 

Curt, use the brown wire on the pigtail.
