Another quarantine chore (battery cables)

Thanks @Flivver250 . I think I will ultimately replace the cables but for the short term, I'm just going to replace the lugs on the stock wires and the terminals on the battery. Other than an aftermarket head unit, I don't have any additional electronics that I need to worry about right now. At some point in the future, it will be a no-brainer to step up to larger gauge wires, if and when needed.

I'm buying 2 new AGM batteries this week and the reason I want new terminals is that on TJ#1, the negative is all chewed up to where is doesn't fit well and the positive was rigged by the PO with the wrong bolt. Easier to swap them both out. On TJ #2 - the PO cut off the factory terminals and used the super cheap ones that bolt the wires down with small bolts on either side of the wire. They managed to jam 2 wires into each and it looks like a failure waiting to happen.

Of course I will be buying a hydraulic crimper as well, as there is no sense in doing this if its not done properly.

I like the copper wire lug kits you linked to and was looking at them earlier today. I just want to make sure the one I buy has the correct lugs for the stock wires so I can replace the terminals on the first shot. I think you are right that 3 of the 4 wires are 4 gauge, I'm just not 100% sure if the one that goes from the positive to the fuse box is 6 or 8 gauge. It measures .249" with the insulation and that leads me to think it is 6 gauge but who knows how thick the insulation is in actuality.

BTW - is there a method to create a link for amazon with the "tag=wranglerorg-20" at the end or do I just add it?
 
What methods are used to connect the battery/alternator to the PDC when upgrading the big three cables? Should I reuse the oem terminal somehow or use one or two copper lug terminals? Any pics are appreciated.

I had mine separated into 2.
 
Your Probably done with cables already but these are hands down the slickest battery cable end crimpers I have ever used

There is also a printable heat shrink tubing for a label maker. Makes for super clean wiring jobs

Also Flexo PET Flame Retardant sleeving is what I used to sheath the battery cables and some of my wiring runs. Keep in mind this was for a boat and may not be needed for your application but it really looks slick and makes wiring runs super easy to pull in tight spaces and its available in a ton of different colors combos
