97 Bounder battery draining
1997 Fleetwood bounder, just installed 2 new batteries, after only 1 day my dash indicator shows low battery again. I live in the RV full time. Prior to purchasing new batteries, intermittently when I would go to start the engine nothing would happen at all. After messing with/wiggling terminals the engine would start but indicate low battery on dash. Terminals are tight and I recently cleaned them but a few months back had another camper cut back the corrosion on one terminal. Could the corrosion be further down the line causing the batteries to not show good charge?
Also, back around same time I noticed converter was making a sound. One of the repair guys I had out stated that it’s probably just the fan going out on converter. And the ECC box makes “cracking “ noise. which I just unplugged converter, not using AC unit to see if battery continues to drain. But I always maintain battery disconnect in “off” position.
and nvr use the lights that work with converter.
Any thoughts as to what would be causing my batteries to drain?? Plz 🤷♀️
