Battery Charging Problem

[papa69smurf 0]

I have an xs d3400 and plan on getting another, my problem lies that my altenator has a run of 1/0 to the vehicle fuse/power distribution then charges the batter only after passing through a 140 amp fuse that bridges the battery connection to the altenator charging wire.  I plan on running a SS Da Vinci for a 2 way 6.5 system up front and some 5 inch rear fill, and an old school SS tarantula.  I will be using BLT4's, will the 140 amp fuse be enough to charge the batteries without blowing, also thinking about taking advantage of a MS-8 processor. please help thank you, also i will have two runs of 1/0 from batt to batt and batt to amp.

Bump. Anyone?

How much power are you running? what kind of wire? and is your alt stock?

130 amp denso alt probably 2000-2500 rms max with two runs of 1/0 ofc

What is your question?

You should be fine. I would bump up to 300 though.

My question is will the 140 amp fuse separating alt and vehicle from battery blow when charging the two xs batts

You will be fine as long as you use at least a fuse rated to what the alternator is rated for.

 

Yes you will be fine.

Cool so 130 alt with a 140 amp fuse would be sufficient to charge vehicle and both batts correct
