So I hook the alternator and AC charger to the common terminal of the
big battery switch, ditch the extra wire the PO had coming off of each,
and I have terminal 1 on the big battery switch go to the starter
battery and 2 terminal go to the house battery. Is that right?



There is a problem hooking it up this way. If you EVER screw up and plug
in the charger with that switch in the OFF position, the full open
circuit voltage of the battery charger, somewhere around 20-25 pulsating
VDC, will be applied to everything connected to the COMMON side of the
switch....without the battery regulating the maximum voltage of it. This
will blow every electronic gadget hooked to it on a live circuit....EVEN
IF IT IS NOT TURNED ON! Electronic gadgets use electronic switching, not
real power switches, those push button on gadgets. It will destroy them

So call me crazy (and cheap!), but could I let a dab of 5200 harden on
the switch so it can't be turned to off? Would everything be safe then?

Thanks everyone for the help!!
