2024 21C with 7,300 miles on it at the north end of the ALCAN Hiway - Arrived Fairbanks to find the kitchen counter overhead light on and could not shut it off unless I turned off the main power switch. This problem developed on the last rough road leg from Burwash Landing YT to Fairbanks AK. I turned on remaining lights while on DC and they all proceeded to cycle on and off in synchrony (this included all lights besides the main center line). Was getting bizarre readings from the Victron monitor on the wall, e.g. 5V and 100% for the battery status. Hooked up to shore power and problem went away, but when I turned off shore power the kitchen counter light came back on and could not be shut off except with main power switch. Synchronous off/on of all the overhead lights and bizarre readings on the Victron wall monitor resumed. Chased all the wires and found that the negative battery cable had slipped out of the connector due to a poor crimp and the rough roads. Re-crimped and all is well. I never would have thought a disconnected negative battery terminal would be able to cause all the weird symptoms.
