75 coach is stock isolator, 78 coach the PO put a Yandina combiner and removed isolator. I am tired of putting my alligator clips on the one with an isolator to charge engine battery when at home. But here is what bothers me about the Yandina, and I am curious if a different connection (or brand) will change it: when plugged into shore power and I am in the coach, I frequently hear a clunk as it connects and disconnects the batteries. the Yandina is mounted on the firewall and is easily heard inside when the 403 is not running. Seems like if the newish PD charger is plugged in, the batteries should just stay combined, but I presume as it reaches full charge on both batteries and the charger reduces voltage, it drops below the Yandina threshold to connect, then with 15 minutes use the PD moves voltage up a bit and it reconnects. If I'm right as to why, do y'all have suggestions to get it to stop? I think the Yandina has a connection available to wire a manual control, but then it seems like a very expensive alligator clip still likely to be left on like I often do on the coach with an isolator. Thoughts?
Moving it off the firewall will make it less annoying, but as I consider solar as well, I'm wanting to both understand and optimize what it is doing.
