I have a 2016 234LR with a 250 Yamaha and dual batteries. I have the Blue Sea Systems 6011 battery switch and the BEP voltage sensing relay, both part of the boat when purchased. Power pulls from both batteries/circuits (starting and accessories), however only the starting battery gets charged when underway. The accessory battery drains down to nothing. My guess is the BEP unit is bad. Any other thoughts?
Thanks in advance!
