2000 Tradewind 7373 Inverter/Charger red flashing lights

When we started the engine to the MH, I heard a loud sound like touching 2 energized battery cables together just louder about where the Xantrex 458 Inverter/Charger was located. We didn't see any smoke and coach batteries appeared OK. We went on a weekend trip and found out the microwave and bathroom GFCI wouldn't work. Reset the GFCI but still not working. Also noticed the heart interface display inside the coach under BATTERY STATE never got to green when the generator was running like it usually does and the AC IN light was in between red and green, the FAULT was red as well as OVERTEMP. DC volts were 13. Also reset all the breakers. When we got home, I noticed a fan sound coming from the inverter/charger area. Opened the bay and the Xantrex Freedom 458 Inverter/Charger had 2 red lights flashing: OVERTEMP OVERLOAD/AGM and LOW BATTERY/GEL 2 and the fan was running. Started pushing buttons near top left, looking at inverter, trying to stop inverter but none stopped it so loosened a battery cable slightly then retightened and red lights stopped flashing. The batteries didn't appear to have any acid leaks and were not warm at this time. Hooked up to shore power and lights were still out. This morning same as last night, the fan was running and same 2 flashing red lights. So this time removed a battery cable that joined 2 of the 4 6V golf batteries and now the charge button on inverter/charger flashes green whenever I hear a click. Fact: the Xantrex Freedom 458 Inverter/Charger was replaced in July 2018 new and 4 new 6V golf batteries around July 2021 and the temp sensor is located near the wall of the battery bay. Checked batteries for fluid about a month ago. I am assuming this has something to do with a battery/batteries gone bad but I would like to hear suggestions from the forum before I begin trying to remove the batteries that aren't on a slide to access them easily especially if you think there may be something else causing the problem. Note: the kitchen GFCI worked and we ran an electric heater like usual for a short period of time in the early morning while running generator. TIA
