Dual Battery Diagram w/ACR, Marine Switch, and Solenoid

You should have no probs running 2 different batteries with the ACR due to the way they sense and charge.. The only time I could see an issue would be if you left the marine switch in the "all" position for an extended period of time...

I'm thinking of finally getting my ACR this week... :woot:

Awesome, and congrats!!

An overbuilt unit is what I like to see... a custom single tray that fits both.. maybe some angle iron, sheetsteel and strategic bracing.. I suppose 2 stockish trays could be configured to work, I just worry about the strength.. Just keep that in mind when configuring the Summit trays...

It two of these boxes.

I hope they fit and work. Seem fairly beefy, and they were the best bang for the buck at $25 a piece. I may weld the two together sometime down the road (when I have a welder) :wink1: .

Wish I had some sweet hook-ups, but you deserve it after working in the field for so long.

I also sent you a PM about the box molds. :D
 
Well, my redtop fits in the box perfectly, but the yellow top I bought to use for my second battery does not. I guess these will be going back to summit. I'm not sure what to use now. Any reasonably priced ideas? I don't think $60+ a piece single optima boxes are very reasonable for my application BTW.

I'm a little lost Kristie, the yellow top is bigger than the redtop? same group size?
 
With all of the grounding you have going on there, where are you grounding the winch? Straight to the negative post or are you going frame/block for that?
 
I've never wired a winch, but I'd imagine unless it calls for direct to battery it'd be easiest to run ut to the frame right beside it. Anyone have another opinion? Or ideas for a battery box?
 
Make sure you do a write-up with your final wiring diagram and everything :thumb:

Nice work so far.
 
Wow. This has been good reading. Learning alot.

Have quick question though... Does the below attached picture excerpt from MiniMull's wiring diagram represent 3 circuit breakers?

If so, how to choose load rating of the breakers that replace fusable links (as in between the starter and factory fuse block)?

Yes, thats her symbol for circuit protection...

My main cab breaker is an 80 amper... an easy way to determine that is to add up the fuses you are going to be protecting... or add up the draws of the individual circuits... I have a few circuits being protected elsewhere, so an 80 was perfect for me... 8 g wire... you always want your protection to fail before the wire..

if you feel like taking a nap and haven't seen it, my thread has the original info on the dual bat/acr gig... like pages 3,4 and 5... http://coloradok5.com/forums/showthread.php?t=194154
 
Well... that makes perfect sense. So, I just need to determine which circuits run off the starter feed and which run off the alternator feed (in the cab) and add up occordingly. Hmmm.

I would like to replace all underhood fuseable links with breakers for now and upgrade the wiring. Dual batteries as well (with an eye towards more future modifications/upgrades)...

Oh, yeah, your build thread's a real snoozer. I think I've slept through it like twice! :haha: Watchin you guys go teaches me tons and really helps me sort out future plans for the Burb. Thanks!
