Hi all, I have a 2010 sundancer. Does anyone know which is the house battery and which is the engine/start battery? My switch has 1, both, 2 and off. When I’m anchored I switch it to the one position and every couple hours I start the boat and let it run for 10 mins to charge the battery. But last week I decided to use the two position. After 2 hours I went to start it and it clicked a few times before finally turning over. There was also low voltage warning indicator that was displayed. I left it running for about 15 mins and moved the switch to both. I shut it off then restarted it and the code cleared. The manual doesn’t say much about the battery switch and how to use it. I always turn the switch to off when leaving even though it’s connected to shore power.
