Yeah. I'm going to do some testing today. I suspect that I am frying my
batteries doing this. I had a look at how my buddies dump truck is wired
-- it uses two six volt batteries to make 12 volts and his alternator is
wired to just one of the batteries (its a six volt alernator) and they
both charge, but I think that the voltage will only equalize accross all
batteries when there is a draw -- and that having the diversion
controller monitoring the full 12 volt load actually works against this
taking place.
Keep in mind this was a serious beer and rib BBQing session standing
around looking at a dump truck wiring with a couple of diesel mechanics
-- and drawing out diagrams on hammes boxes.
Give me another 10 years of screwing around with this and i'll know what
i'm doing ;)
