Thanks Richard, let me rest a day or so (plus we have to move the coach to a different site today) and then I will tackle the batteries again. I noticed on Tom’s coach that the fuse link was placed inline differently than mine (I think his as on the ground wire). I also talked to an electrician at Newell and he suggested, but could not verify, that some coaches were possibly wired with the disconnects on the positive side like mine due to the engine but I’m not sure how that would matter (we have an S60)... maybe when the batteries are all merged for starting? I have no idea if that is true or not...
I will improve my drawing this week and re-post when I get it done...
I re-read your post and I believe I am basically wired the way your coach is - everything going to one lug. The batteries are daisy-chained (parallel?) to each other rather than all running from the lugs (which I think would be better).
I have to figure out why the batteries are charging when they are all on the same switch vs two separate switches. I need to ohm out the second switch to test it - maybe it’s bad.
