16ace and harry....that is it! the pict in the link looks just like the one that is doing all the clicking except mine is not lithium. interesting that all the research i did building my solar system and battery upgrade i never came across this item. OR, i just didnt notice it. you folks are the best, thanks much for your time, care in contributing to what i consider a great place to be. I have very much enjoyed this last year of rv fun, learning, upgrades. come jan 8 i retire and we depart on our full time journey. our house and most stuff is sold and gone. very much look forward to meeting, becoming one with the rv family of friends out there. thanks again, lots.
follow up:
I just located the item on amazon, reading the description = "Under normal charging conditions, the BIM will connect for 15 minutes every 35 minutes. That means that the BIM will connect for 15 minutes, disconnect for 20 minutes, and repeat this cycle until the coach battery is charged" this is EXACTLY what is happening in my case. $172, the cost of a good nights sleep! i cant say THANKS enough!
here is a link to amazon item for those that may want to see it

one more thing, i have purchased a dc to dc charger to put between the alternator and lithium batteries, yet have not installed it, on my list of things to do. any thoughts on a dc to dc converter? my research leads me to believe this is needed to keep the load off the alternator. my alternator is 120a, the dc to dc i purchased is a 30 amp, i figured that was all i needed. I haven't figured out the correct wiring for it yet. in reading about the LBIM, i wonder if it does what the dc-dc does, i dont need the dc-dc with the LBIM?
