    I am in the process of planning out a dual battery setup for my 2015 TRD OR. After researching several products and threads, I think I have it narrowed down to what I want, but I am having difficulty with the proper wiring schematic for what I want. I am not an expert electrician by any means, but I can follow clear direction. This is what I want to use:

    [​IMG]Blue Sea Systems ML-ACR
    [​IMG]Blue Sea Systems ST Blade Fuse Block
    [​IMG]12v LED Double Battery Voltage Monitor

    Similar to this setup - 687474703a2f2f696d672e7461706174616c6b2e636f6d2f642f31342f30372f31382f34617665767533752e6a7067.jpg

    The wiring for this part is easy.
    photo-2.jpg

    I've seen conflicting wiring diagrams. The first diagram doesn't show the Blue Sea Systems 12 circuit fuse block with negative bus. On this diagram, there are two switches. Which product do I need for this? Do I need a solenoid switch? If so, the second diagram is for a Blue Sea Solenoid Switch, but its drawn as connected to the starting battery.ML-ACRs.jpg

    image002.jpg
    I want to get my hands dirty and do this myself, but I also don't want to burn up expensive equipment because I left something out or connected something backwards. Any help would be appreciated. Thanks.

    I've seen Crom's setup and I like it. I'm not putting in a roof rack just yet, but it's planned. After that, I'd definitely consider adding the solar. I have somewhat of a checklist of mods in a certain order based on budget and practicality that I'm trying to follow. The dual battery is the beginning for me. I don't think I've seen Dj's. Time to surf a bit more.

    Yeah, Crom does nice work.
    DJ doesn't have one in his rig (yet :devil:). But he is a great guy with a wealth of know-how about electrical work.

    That's exactly what I'll need. Electricity isn't my strong point, unless I'm defibrillating someone, then I've got that covered. :)

    The first diagram is the one you are interested in. The top most item in that diagram that looks like a breaker panel is where the blue sea fuse block will go. In a large boat this is in fact the connection to the master breaker panel, which is why there is simply a switch in line, as it would have its own master breaker that would trip if you draw too much power (just like The breaker panel in your house). Since you are using a blue sea fuse block in that spot, you should place a breaker inline, instead of the switch. Double check, but I believe the blue sea fuse block is rated for 80 amps, so simply put an 80amp breaker in line. That is exactly what I did, except I used a bussman relay box as opposed to a blue sea fuse block.

    The second diagram is simply if you want to use the ACR as a relay to enable/disable starting the engine.

    Hope that helps

    Do you have a link for a particular breaker?

    You don't need the battery switches in the diagram. Those are for a boat, which disables electrical for when the boat is stored or dry docked. Agree that first diagram is the one you want.

    Also you don't have to connect all the wires for the ACR-ML product. I believe you only need to connect 4. Battery positive(s), ground, and isolation #1 (brown wire). Can't remember though, it's been 2.5 years since I looked at one.

    Can you advise the proper size fuse for post #11 above with the blue arrows on the left?

    Thanks. I wasn't sure, but that clarifies it for me. Yes I do want the ability to jump start from the auxiliary.

    This better?

    I don't need to push limits with electricity. 100A I'm sure will be plenty.

    I agree with @DoorDing I wouldn't push anything beyond 100 amps. that will be good enough! sorry at work, can't always respond!
