Sorry Deer season kinda got in the way of the project but as of now its finished.
This is the wiring diagram I drew up for my set-up.
Heres the switch set-up. I stayed with something similar
to the Painless system in form and function.
To keep both lights from lighting up when the switch
was flipped I used a pair of diodes from Radio shack.
The swich is a DPDT on-off-on 6 pin switch (only 4 pins used).
inner workings. For my pannel I used a scrap piece of .062 steel
and secured it with a leftover tube of permetex.
I decided that I wanted a couple of fuse blocks,
the one in the back is hot with the ignition on
(power coming from a C.D. silonoid triggered by the ignition),
and the one in front is hot at all times
(wired directly to the batteries)
The silonoid on the left is a continuous duty 200 amp.
used to conect the two batteries together.
The one on the right is what switches power
to the key-on fuse block
position 1 (center) on the switch is off and only
battery 1 is used.
Position 2 (green) both batteries connected and
charging only when the ignition is on.
Position 3 (red) both batteries are conected together
at all times reguardless of key position.
This position would be used to jumpstart your self.
So far all is working well and there are no glitches
with the system.
I don't have part numbers at hand but will get a list
together tuesday when I get back to work.
