Dual battery setup question - starting from aux battery...

Again, Ryoken, you are the man on 12V. I kept wanting to say drum switch, but it just wouldnt come out right. I should prolly stop grasping and just use more relays.
 
depends on what was being drawn on the aux bat....
 
you can take your excite lead right from the main charge post on the alt... just piggyback it...


here's my 1/2 done diagram of mine.. the red circle is my marine switch. the blue circle below it is the ACR, the orange wire coming off it is the parallel trigger running into the cab to a parallel switch......

you can use either bank as a primary with the marine switch, both charge all the time as needed due to the ACR.. they can be paralleled with either the parallel switch from the ACR or by putting the marine switch to all...

the slave solenoid is what many refer to as the "remote Ford solenoid mod"

I know I'm late to this party but I am noodling out my setup and I expect it will be similar to the above. I have a (dumb) question, though - what function is the slave solenoid performing here? Also, what P/N is being used? Is "cab feed" an ignition hot?

I'm assuming "cab breaker" here means a fused/breakered hot coming off the switch to power your relay bank.
 
the slave solenoid is what sends juice to the starter when the key is put to "start"... thats what the "signal" wire is for, fires off that solenoid when in the crank position.. it's just a continuous duty solenoid... most guys run 90 amp stuff from napa, etc for about $25.. mines a 450 amp bluesea version..

cab feed is not an ign hot.. it's the power feed to the cab, hot all the time.. it does feed the ign circuit.. thats what the cab breaker is for..

that relay bank is fed from multiple sources, depending on the relay... theres 6.. hi beam, low beam, 2 for fans and 2 for the volt gauges..

one of these days I'll finish that diagram.. :doah:

Okay, thanks. Next questions:

Q1: I assume the purpose of the solenoid is to bypass the on-starter typical GM solenoid setup.

Q2: How is the ACR doing its job in your diagram with it being piggy-backed onto terminals 1 and 2 of the marine switch with the batteries' positives also going there? Seems like they would receive charge (one, the other, or both) solely depending on the switch position and, since they are connected directly to the switch, isn't the ACR basically cut out of the loop when it comes to voltage sensing and routing the charge to one or the other?

Thanks for the other explanations. So, if we were to recap all the notes for your diagram so far, would they be -

1. The blue circle is the ACR (http://bluesea.com/category/2/productline/overview/389)
2. The yellow "cab feed" is a constant hot that is the power feed to the cab, hot all the time.. it does feed the ignition circuit as well and that's what the "cab breaker" is for.
3. The "slave solenoid" sends juice to the starter when the key is put to "start". That's what the "signal" wire is for, it fires off that solenoid when the ignition is in the crank position. (Solenoids - http://store.summitracing.com/egnsearch.asp?N=115+%2D122283)
4. The "signal" wire to the solenoid is the ignition wire that goes hot when the ignition is in the 'start' position.
5. The red circle is the marine switch.
6. The orange wire coming off the ACR is the parallel trigger running into the cab to a parallel switch (with this setup, you can use either battery as a primary with the marine switch. Both charge all the time as needed due to the ACR as it is voltage sensing. They can be paralleled with either the parallel switch from the ACR or by setting the marine switch to "both").
7. Not shown - you can take your alternator excite lead right from the main charge post on the alternator.
8. With this setup, the alternator charges at the "in" side of the slave solenoid, basically the "common" output of the marine switch... it's the orange "charge" wire.
 
yeah, the slave is a remote solenoid for all the obvious reasons, hot start conditions, keeps that 12v constant hot off the starter lug, gives ya better place to pick up power than the starter lug, etc, etc...

perceptive on the ACR... what happens in my case is you run the marine switch on 1, or 2... all puts them in permanent parallel.. what this does is allows you to use either "1" or "2" as your main bank, the other as your aux... if you run in all, the ACR just doesn't close contacts, as both posts are over the kick on limit...

when in 1 or 2, the ACR closes as needed to charge the aux bank...


1. yes....

2. yes... everything in the cab, including ign "on" feeds back to the engine compartment derive from this feed...

3 yeah, the slaves are also refered to by many as "the ford remote solenoid" mod.. but i refuse to refer to it as that.. it is a slave solenoid... been done on boats, trucks, etc for eons...

4 yes. it's basically the "S" wire from your starter...


5 yes... http://www.keenzo.com/showproduct.asp?M=BLUE-SEA-SYSTEMS&ID=1197524&ref=GB

6 BINGO!

7 yes, mine is that way... same piggyback method with my starter...

8 yes...


just a note on my system... being I'm gonna be running front and rear winches, expect some pretty big changes and additions when the truck comes out in the fall.. especially pertaining to whats running in and out of my electronics box and cable routing...

the basis, and theory of the system will be the same tho...
