On corrosion, trust me there will be.
This picture shows a good place to check for corrosion. As may have been mentioned earlier, it is on the passenger side of the engine. Both ends of the cable should be taken loose and cleaned to shiny metal to ensure a good ground, even as just a preventative maintenance item if you are working in that area on something else:

Hope you find your culprit.

I'm a little confused on the location of your referenced cable. Is this under the engine? I thought it would be in this area on the passenger side (photos attached)

Thanks for the help..

Passenger side, underneath in the area near the motor mount. Look for a braided strap.

The link in my post above shows a photo, as mentioned by jmo69, it's near the engine mount. Down towards the bottom of the engine. The picture in the link was likely taken looking down on the motor mount on an angle from the front.

13.6+ is fine.

For the next person reading this:
1. Get a multimeter and learn how to test alternator output at the alternator. At the very least test at the posts by the drug bin while the car is on.
2. Unless there is a diagnosable issue with the alternator itself, buy a new voltage regulator. Super-easy to install, and saves $$$.
