Dear Gurus,
Battery isolators are just large diodes which function as one-way check valves for electricity. A good meter will indicate 0.72 v drop across a diode. That is just normal.
Lead acid batteries normally "like" around 13.7 volts when it is hot outside and up to 14.2 volts when it is cold weather. If you have 13.7 (with an accurate meter),
the batteries should charge and stay charged.
However, I'm not for sure which Newells have isolators. For example in out 1991 #277, Newell and the book states I should leave the battery bus tie relay on all the time.
It appears to me another good source of isolators AND big alternators is HD Power Solutions (817 535-0284, 5083 Martin Luther King FWY, Ft Worth, TX 76119, [email protected]). On our coach, I really needed the power output opposite of where it normally is and they changed it around for me. If you contact them and tell them your needs before they build and ship your unit, it is a no charge request.
Happy RVing!
