CS144 Alternator, is this damn thing wired right?

[MrSony]

It seems to be, the Alternator works, it now has a brand new battery manufactured two months ago, and it still has trouble charging. It will eventually but it seems the Alternator has trouble with the first initial "kick" and doesn't like to start charging. I've also noticed my batt light doesn't work. Could that have an effect?

May want to move the regulator "sensing" wire to the starter terminal. Make sure your grounds are clean, I had a charging issue caused by dirty alternator brackets affecting ground.

I have a CS144 wired up on my Caprice.

I went from a CS130 so it was an easy swap. You went from a v belt alt?

You have a dummy bulb or volt meter gauge cluster right??

Because the brown wire, goes to that. The red, should work like shown.

If the vehicle charged fine previously?

I would send it back and condemn the rectifier bridge 🤷‍♀😥😥😥

With the key on there should be about 12 Volts on the brown wire.

Regal with idiot lights. Brown wire goes to that.

El cam is directing you.

If your idiot light isn’t working ,and it previously was, then you don’t have it hooked up correctly.

It sounds like your pigtail has the F and L pins swapped on the alternator pigtail. Look at the attachment. It appears you bought a generic pigtail for the alternator, it will require to be wired differently depending on the setup the vehicle has. I doubt the alternator is no good, but anything is possible.

Yes. 10/12si to cs. I have the correct conversion harness without the resistor, as the idiot light I have is the resistor.

The odd thing is that it's a decently made plug that came in an original ac Delco package.
