[QUOTE="dsmyl6, post: 8313568, member: 655655"] I did a little work on the electrical tonight. So the truck has two batteries, both batteries are directly connected via a 125A fuse and 6 awg wire. The main battery is 80 amp-hours and the second is 60 amp hours - I ordered a Duracell 100 Amp-hour battery, I am debating if I want to interchange my main battery, second battery, or simply add the Duracell in the cab. I decided to leave the connection between both batteries stock and upgrade the alt -> main battery and the main battery ground with 1/0 awg wire. Before the upgrade, I was sitting at 13.8 volts running, with the upgrades I idle at 14.3 volts. Below are some pics. The upgraded ground - finding a decent ground was a struggle, I ended up bolting it to the hood frame stiffener [IMG]http://i1351.photobucket.com/albums/p781/Danny_James_Smyl/Ground1_zpsbce79921.jpg[/IMG] The second battery - pretty simple setup.
