One end of the cap has been 'blown out', and it now physically has a problem, in addition to the obvious electrical problem.

Electrolytic capacitors will sometimes blow the aluminum casing apart when they fail. They can sound like a mini firecracker when this happens. It does make it easier to locate the problem area of a circuit. The failed capacitor can be a symptom or cause of a problem. This type of failure unusually results when the applied voltage exceeds the capacitor’s rating.
[b]Converters: I would agree with the comments that the voltage may rise from a converter when the battery is disconnected, but
not to a point that would cause a motor to burn up,
light covers to melt and the eventual failure of the converter. That converter company would be out of business soon and would have to have warning labels posted.
Warning: In the event of the battery fuse opening, or disconnecting the battery - the converter voltage will rise to a level that will burn up all attached equipment then self destruct. This just isn’t the case. The voltage
may rise to a level that would cause problems with
some LED type
lighting and that would be about it. Good luck Pat
