PA Performance 200Amp Alternator Not Charging Help!

My car had, I believe, a PA Performance alternator on it before which just went bad.

So I bought a 200AMP PA Performance alternator and it seems like the wiring is very different.

I'm not sure because I didn't install the first PA alternator so not sure about the wiring.

The new alt calls for the black and orange power wires to be used and put on the power point on the back of the alternator, along with a large fused wire that goes to the solenoid.

The large fused wire was already connected, from the old alternator, but the black and orange power wires were not used at all. I found them taped up farther down the harness.

I connected those with eyelet connectors to the back of the alt along with the power wire and the alternator isn't charging at all.

Checked the ground with a multimeter and it's good. Checked the fuse for the larger power wire and it's good... but the alt isn't charging and I'm not sure what to do at this point.

I included a picture of the wiring, one of the eyelets came off when I pulled on the wire but it was attached along with the other orange/black wire... but the alternator doesn't charge.

If anyone knows why this might be happening I'd appreciate it.

Well to update... I found the issue.

Contacted PA Performance and they gave me a diagnostic rundown.

Found that the "Ignition On" wire (the green/red stripe wire) wasn't getting any voltage when the key was on.

Then remembered I just replaced the speedometer cable.

Removed the cluster and found that the printed circuit board was damaged... jumped that with some foil and it is now charging.

Now I'm off to try and find a new printed circuit board for my cluster :/

we would have gotten to that

no biggie, good you found the issue

you can solder a jumper to the board, as it hard to find just a new board
