Putting batteries in the back

[bryan strickland]

If I put the house batteries in the back of the coach I guess I have to run
a big battery cable to the solanoid switch that hooks up to the engine for
auxiliary battery. Do I have to switch anything else? Or is there another
way to do this and be safe at the same time.
Thanks for any feed back

IHMO: & SWAG: (without proper calculations)
If you intend to use it as an aux battery for starting, I would consider cable
atleast one gauge larger than stock, possibly 2 gauges, to allow for
loss/length/amperage requirments.
also make sure that the battery is in a well vented area, with an acid proof
tray AND secured in-place. the ride can be a little rough at the tailend.
a conservative thought would be to add an additional ground cable as well,
this
allows for possible resistance in the frame to frame connections, which could be
a problem considering the age of our "ladies"
other than that, I forsee no other problems..

Big difference in the amperage requirements of the Onan and the 455.
I would not see a problem with the normal cabling for the Onan.

FWIW: I use 3 batteries in our 73 one engine battery upfront, the house
battery also upfront and one battery back in the onan compartment and its on
its own circuit.

Do you not have a house battery in the back. If not, and you decide to
put one in, yes you should run the largest cabeling you can to keep the
resistive load down and to get the highest voltage from the front to the
back.
