Could also signify something more significant and potentially hazardous that could damage the BMS. Might be a good idea to check for continuity/resistance between the + and - output end, in case it's shorted between them somewhere.
Plugged into the wall, it use to spark harder sometimes when plugging in battery. When it failed, the spark at battery was weaker. Charger would draw power for charging light LED but not for the red "ready" LED for connection to the wall.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
