Harold:

thanks for your clear and detailed explanation of your isolator and how you set
everything up so that both batteries would be charged while the engine is
running, yet the aux battery would be isolated when the engine is off, and the
refirdgerator would only draw current when the engine is running.

What I do not understand....and I am not addressing this question to you since
you have already written so much....is i thought you could accomplish all of
this by using the relay under the seat.  Everyone seems to say that if you
connect the #30 post to the + aux battery terminal and to the refridgerator,
you get the same result, including the charging of both batteries without over
charging of either.  I understand that you believe the camper relay was not
intended for this purpose, but was intended only to isolate the
refridgerator.   Anyway...thanks again for the detailed info....your set up
sounds like it is what i want.
