Correct Coach Battery Wiring

[Stephen]

Hello all-
I did verify-- My charger does work-- but only when I start my
Gen... Not sure, when plugged up to 30A at the house, does not
charge.. Maybe because not 50A? -- I think Im going to look into
what Bruce was talking about with the Xantrex...

however- I need to make sure that my coach batterys are hooked up
correctly in "series-parallel" as the manual says. Does anyone have
a diagram or drawing of the correct hookup of these Four 6 Volt
Batteries?

I understand the series hookup to make the 2 6 volts to 12 Volts,
and the parallel to make the 2-12's double capacity...

Three wires are 3 GROUND connections to the bus frame,

2 POSITIVE going to another part of the frame(a terminal block it
looks like)

and 1 thick Positive running back to the Center/rear along the frame
(maybe to the charger?)

and 1 smaller red one running to under the couch to the terminal
under there.

Then there is a small silver-receptical looking box beside; mounted
on the wall with 4 wires running out, all taped together, they are
all cracked, and hard (got hot?) maybe that is (or was) the battery
heater

I was thinking that maybe one of my charging/ battery problems was
the way the previous owner had this rats nest of battteries
connected up. Any help would be appriciated. Thank you.
