how often are you having to tighten the nuts on the battery?

sounds like you may have too many accessories on the main negative post that's affecting the clamping.

Post a pic.
 
One thing that happened during a road trip, I was getting some odd things happening with the dash lights. My wife looked up on the forum what could cause that and it looked like a loose battery cable. When we stopped I found the negative clamp was loose and I couldn't tighten the neg clamp down on the post tight enough. I was able to still move it around by hand even though the clamp was fully tightened. Stopped at a dealer near by and when they looked at it they found the clamp wasn't pushed fully down on the neg post which was the reason why I couldn't fully tighten the clamp because of the taper in the clamp (or post, or both).
Might be something to check.

yep.. those side posts have no clamping power and if you're wheeling they loosen fast. It's been a while since I've owned an optima but in my experience you can't tighten them too much or they'll pull out of the case.

you want something like this:

looks like you have one already, i'd look at the flat style
 
One of my sky high terminals failed on me and the company didn't give a shit about it. I wouldn't recommend them at all myself.
 
Everyone of those clamps where you've stripped the cables back and slid them under the tin piece is a potential problem.

You should use crimp on cable ends and then solder them.

The electronics on today's cars are very sensitive and with computer controlled charging systems (not sure if Jeep uses this) any extra resistance will throw a curve ball at the ECU whether or not it's controlling the Alternator.

The side posts (with the correct cable ends) can be used for running the Jeep and the starter (GM did it for years with no problems) but the top posts should be used for the winch since it draws a lot more amps, for longer, than the starter ever will.

YMMV RON

It would be better.

Best would be new or redone cables w/o the tin clamps holding the end of the cables. Those are "get you home clamps" if you damage something on the trail.

Cables that look something like this pic would probably solve all your problems and make your alternator and winch much happier...
