Hahaha... thanks Stu...Dan, that looks just like the two switch diagram in this link provieded earlier: http://c34.org/bbs/index.php/topic,6604.0.html
Looks like "Ya Got It!" :dance:![]()
I just realized though that the BSS 7600 ACR would try to combine the isolated start battery when the AO rises to the 'combine' voltage. It seems that if I had a dead cell in the start bat it would really work the alternator and draw off the house bat. Looks like I need to hook up the On-Auto-Off feature on the acr to be able to lock it open.
