Hey y'all, I recently installed a new timberline hydronic heater in my camper and have run into an electrical issue. I've narrowed the problem down to the fact that the heater is prioritizing draw from my starter battery instead of my house batteries. I'm wondering if you guys have any suggestions as to what could be causing that to happen. I've mulled over the idea of integrating a switch between the starter battery and the heater; as that line is auxiliary and only meant to be an emergency back-up.
