Why do this swap?
Having problems with dim lights, weak idle, or things shutting off?
Upgrade your amps form 55* to 95*
Eliminate External Regulator
Things you need:
Saturn Alt. from 4cyl. 94-97 ($30)
3TC Alt. Pulley
basic tools and knowledge
Start with the SAturn Alt.
First you need to take the Saturn Pulley off to replace it with the 3tc pulley. but leave off the 3tc pulley for now
After the above^^^ place your 3tc pulley on the saturn alt. keeping the saturn fan spacer.
get your bracket and grind her down!
grind a bit off the casing, not too much! its a thin case!
when installing, your belt may go right on with no problem. i had a small belt, i needed to place it on all the pulleys before installing any mounts. what ever works for you.
this is how much adjustment you get from all the work yo have done! maybe more if you grind more and work harder at it. also Rooster_Cogburn says he drilled a new hole for better angle, i didnt.
it should look like this now
you can hook up your large thick wire that goes to the battery, just as you would on your regular ALT. its the single wire that is bolted to the casing.
Rooster_cogburn says to get a thicker wire or fusible link. i didnt.
the stock Saturn ALt. has 2 wires
the 3tc has 3
i used 2 from the 3tc
test the wires with the key in the "on" position and test the plug with a volt meter
you should get 2 of them with 12v
and 1 ground.
i tested the saturn alt. with both 12v connections and it worked.
the saturn striped wire goes to the 12v on 3tc
the solid goes to the ground on 3tc
eliminate the voltage regulator
I have a 82 SR5. my charge light came on after this swap. i need to figure out what i need to do to get it to work again.
