2024 Grand Design Imagine

Faulty panel wiring but everything works on shore and truck power. Called Grand Design (case #00996054) and was told it was a bad LiFEPO4 battery . I open the distribution panel and the schematic shows I should have 2 red wires (one to converter and the other to the battery) but I only have 1. Solution: Issue was in the original wiring from the factory. I called GD again and tech noticed the red wire was there but incorrectly connected to the DC fuse panel side (essentially bypassing the converter) as "battery disconnect." For my sanity I spent $165, not reimburseable per GD, and had a RV service tech come out and confirm the wiring was now correct and was told once I got a new battery everything will work as intended. I purchased new smart LiFePO4 and now all 12V equipment works as it should both on and off shore power. In conclusion, I've had no battery power once both the OEM and replacement LiFePO4 batteries went dead because they were "NEVER/EVER" being charged since the batteries were "NOT CONNECTED". This meant the battery disconnect never functioned from the beginning and when the RV battery disconnect is switched to "off," it severs the connection between the battery and the RV's 12-volt DC system and therefore the battery will not power appliances or charge when connected to shore power. By connecting an RV battery directly to the 12V DC panel (bypassing the converter) means the battery becomes the sole power source for all 12-volt appliances. Issues: Limited power duration--12V items will run until the battery drains, which can happen in a few hours/days depending on usage. No automatic charging--The battery will not be recharged, as the converter is not in the loop. Once the battery dies, you will lose all 12V power. Safety risk--The battery is likely connected to the panel without a battery disconnect switch or proper fuses, creating a potential fire hazard if a short occurs.
