Flickering or pulstating Headlights

Update: Big thanks to 67Dart273, and Superchargeddrt.

This fix worked perfectly, while I was at it I replaced some wires completely, new connectors everywhere, crimped, then soldered and covered with heat shrink tubing.

Now, with the car off, but key in "run" position. I can probe the Ing wire right before the regulator and I get .20v much better that the .95v I was getting before.

Totally fixed the flickering lights, and the corresponding squeek from the alt every time they flickered.
Lights are nice and bright and steady.

Checking charging rate at the battery with car running at idle still fluctuates a little but way better 13.9 - 14.45 Was charging over 15 before.

Thanks again guys.
If I can get the video off my phone I'll post the difference in the lights.
