Battery Cable size
Anyone know the gauge of the factory battery cables on the Ex's? I'm trying to eliminate all possibilities with my constant need to replace batteries and alternator every 6 months or so. Thanks. I was going to upgrade to a 2/0 or 1/0 marine grade tinned cable since I can get all marine products at cost and the tinned wire resists the corrosion the best.
Thanks in advance

My nephew had a similar problem with his 6.0 F250. Turns out some bonehead PO or mechanic had tapped into a fuel injector power wire to get power to something else.
Wiring was fixed and there have been no dead batteries or dead alternators since.

That said, w/ the amp draw of your 7.3s starter likely the heaviest load, you will be fine w/ 1/0 (up to 15' total Pos & Neg run).
Make sure you shrinkwrap, use proper crimping tool & use correct lugs on all connections.
Based on your symptoms, I would be replacing the alt output wiring as well.

Check and see if you still a blanket around your batteries. This is what was killing batteries on my '01 Excursion every 2 years every fall. Since removing them, the only problem I had was the Texas heat drying them out. That's since been remedied by keeping them topped off with distilled water.

I have a 2000 with a V10. Ours were 4 gauge. The ground cable is stripped in the center and has a tab that is bolted to the frame. When I made new ones I ran a cable all the way to the engine and then made another cable for between the engine and frame. I used 1 gauge I think. There are pictures in the thread I did of installing our Banks headers. Sorry I don't know how to link to it. Carquest made the cables for me.
