The small wire comes from a switched source.
It gives the regulator in the ALT feed back to let it know what the voltage is
after it’s been passed true the fuse box.
The resistor is just a way to lie to the regulator to make it put out more.
Some people will get this confused with needing a diode in the signal wire,
on older GM cars when using a MSD or other aftermarket ignition boxes.
In some case the cars would not die after turning the key off dew to a back
feed through the signal wire.
You do not need a resistor to make your ALT charge.
Turn your key to the run position and unplug the small wire
and test it for voltage.
If it has voltage you have it plugged into the wrong place on the ALT
or the ALT is no good.
If you don’t have voltage to the wire check your fuse box.

If you read thru prior threads on this you will see that other people have had this problem and had to go to a overdrive pulley on the alternator.
Not charging is not showing anything and running off of the battery, two totally different problems.

11.2 means that the alternator is being ignited. It isn't chatging at the optimum level.

if the battery is reading 11.6v while the car is running, its not being charged, its being drained. the alternator isnt doing anything. if you have to put an overdrive pully on the alternator you have problems.

unfortunately nobody carries the optima in stock so it will take a few days to get another :-/
on that note, im ready to return this thing. With the supplied hardware, the alternator does not fit (back of the alt hits the head) so i shimmed it a bit with 1 washer on each bolt so that the alt clears, but now the pulleys are misaligned causing a squek. Anyone else ever notice that? I dont want to grind the case of this alt, because it looks like ill be grinding all over it to make it clear.
i made a $2 bracket that I fabbed that works way better than this, I just wanted something that looked a little nicer.

if someone could give some advice on the fitment as well that would be great. Im pretty frustrated at this point.

whats the voltage of the batt? there shouldnt be more than a .25 - .5 v "voltage drop" from the batt to the signal wire.
whats the point of the alternator? more amprage? honestly, if you're having this much trouble is it worth it?

Mine did not have to be shimmed but i did have to drill the holes to the correct size. It wasn't worth what we paid. But i just went and bought a autozone alternator and pigtail.
