Okay,

Up until a couple of days ago, I was going to go with a complete battery management system.

Now, after looking at various websites, and this post Winch Wiring Options, I decided to go with a marine dual battery switch, by Guest.

I have purchased the switch, and it is wired into my system, presently.

It's wired as follows:

Feed = Alternator charge wire, starter cable, and wire feeding primary electrical in the Jeep.
Battery One = First Optima Yellow Top
Battery Two = Second Optima Yellow Top
Field disconnect = Not used, I am using an internally regulated 'Chevy type' alternator.

My questions are ...

If both batteries are connected to the system (using the "both" position on the switch), will they be charged equally?

Should I install a separate isolator, to assist here? Or would it do any good?

I can't help but wonder if, the alternator will 'sense' the higher charged battery, and stop charging.

I appreciate all responses,

Got the pics taken today. What do ya think?

Here is the switch, mounted and ready for service:







I would like to thank the guys on the thread (Winch wiring options), for the idea of this install. I didn't go through the complexity as some did (mounting it in the tub), but I feel this will work very well.

Thanks, but unfortunately, I can't take the credit for the idea. Other Off-roaders have done it before me.

I just realized it was an excellent idea. You don't have to beat me in the head with a stick, to realize $70 Bucks is cheaper than $140 (my cost on a battery management system).

what purpose is this dual battery setup? winch? onboard welder? you like to leave your lights on? killer sound system? for those long trail rides down the logging road?

but, it does look good, i'll give you that.

Actually Skitzo,

I had a problem where either my alternator died, and took my primary battery with it, or the battery shorted and killed the alternator. I still don't know which.

Now, I use my winch pretty often, plus have Amateur Radio equipment and off-road lights (to install again ... another story there) that draw a fair amount of power.

(edit)
Oh, I forgot to add to the draw ... the 2k watt inverter, I'm trying to get, at a local pawn shop.
(/edit)

Translation: Something else to spend money on, for my Jeep. <IMG SRC="smilies/smile.gif" border="0">
