Finished my big 3 upgrade.
Used copper wire terminals, marine grade battery terminals, solder, wire loom, and a lot of electrical tape.
Wires i've replaced: Neg battery to chassis, Neg battery to block, Pos fused link to alt, Neg engine to chassis.
Took me a whole day, its a pretty time consuming mod, but the benefits for me is worth it. Before the big 3 i had 13.1v when running, which led to be believe my alt was going out, after big 3 i have 14.3 when running, which tells me my alt is still good(god knows how) after being under mud water for a good 20 mins and the occasional mudding trips.
Also i got rid of the bass lag, before the mod my bass hits about a beat behind the music, but now the bass is on point, which is one less annoying thing to think about when driving.
Pics tomorrow.
