I just got done upgrading all my battery cables. My terminals were cracked and corroded and not making a great connection. And when i pulled the cab the second time the connector on the Pass positive terminal broke. and we just got it back together to get it running.
I was having issues with my voltage and decided it was time to get the crap out and start over.
I bought all new cables, terminals and lugs.
I ended up just extending the starter cable, its 3/0 gauge, about a foot because trying to route 3/0 gauge is PITA and the cable was already big as sh*t and in good condition.
The Negative cables come from the factory at 2/0 gauge. I didnt upgrade them, just replaced them with 2/0gauge wire, and one thing id did was cleaned up all body contacts.
The battery crossover cable is factory 1/0 gauge, and up graded that to 2/0 gauge.
I did have to cut into the factory alternator and fuse block wire to crimp on new lugs so they can attach to my new Military style battery terminals.
As far as upgrading the alternator, i built a 0gauge wire to piggy back the factory wire, and in that piggy back wire i put a 250amp fuse block (my alternator is 220amp unit from powerbastards.com).
All in all it was big task and time consuming task to get it done. Just remember to have the right tools to do the job right the first time and properly, (meaning cable crimper, large gauge wires are not fun to crimp. i have a 12ton hydraulic crimper to do the job, makes nice air tight crimps.)
But now that im done, im glad i did, for the piece of mind and expandability and knowing that everything is making a good solid connection.
