This may be due to a loose fuse terminal for the low voltage high current fuse (3A). If this condition is present, compare fuse removal effort between the low voltage high current fuse and like fuses in the battery junction box (BCMC). If removal effort for the fuse is low, replace the low voltage high current fuse panel assembly to correct this condition.
