Sorry guys I've been at work. Wiring is 2 runs of 0awg to the rear batteries with big 4 done in 0awg. Don't have an amp meter but batteries read 12.6 volts. I have duralast starting battery and 2 autocraft deep cycle secondary. I was mainly just curious if it could be done.

Also have 2 10 farad caps wired in, 1 for each amp

don't you have 4.6L? i think its just the 5.4L thats PCM controlled.

Oh, yeah, that could be the possible difference.

I'm planning on a much smaller scale version myself. I've got a 400 amp Harley Davidson battery, I just haven't figured out where to mount it yet. I'm also holding out because I may need a new starting battery. If mine goes out then I'll just get a chevy battery because of the dual batter connections to make wiring a ton easier.

jmt0645 - Didn't you forget to mention the electric chair you have bolted in back there in the bed? I know with the setup you have you must drive around to the prisons "to give them a hand" with some of their "disposal" chores. :hehe:

With the wiring and alternator you have, there are NO power losses. Things are fine just the way they are. 12.6V no load is fine too, especially if you didn't disconnect the cables from the batteries. With three batteries wired in parallel, the voltage you see will be that of the weakest one.

:rofl: i can probably help help them alittle bit
