Me? Very simple set up. I didn't even drill the charger in. This is where I put it and hold it in place with a Velcro mesh. Each set of wires goes to + and - on battery.
Probably because he’s been given 2 starting batteries by his dealer....
Yes, it is the ground wire like @Julian states. There are a few ways to do the "DVSR mod" so that the smart charges can do their thing. I chose to simply use a winged nut and remove the ground wire whenever I am using the charger. If you don't do any of the dvsr mods, then when you plug in the charger, the dvsr will activate and essentially charge all banks as one big bank, turning your fancy expensive charger into a dumb one.
I have the exact same model as your and just dropped in 4 pair of Wetsounds Revo 6 and a 12" FA Sub with two decent amps. I spend a ton of time anchored with the music running and would love to know more about your exact set up (batteries you used, wiring diagram, etc). Sounds like you have exactly like what I am looking for and need. Would you mind DMing me or replying with more details? Thanks!
