wiring a second battery w/ relay


Recommended Posts

So when i put the second battery in the cargo should i have a run from the alt to each battery or just to the front one?

alt to front batt (in 1/0 gauge) then a run of 1/0 from front batt to back batt. for grounding, you can run another 1/0 run from front batt - to back batt -, OR you can just take a short piece of 1/0 from back batt - to frame (paint sanded off so its nice shiny metal)

edit: i hope to god you have the big 3 done also

big 3 as been done before i put audio in it... was just curious cuz i seen it both ways just wasnt sure if one ways better than the other

edit: yes 1/0 is all would use... bigger is better i have always seen
