Perhaps a noise filter

If its the size of a soda can, Id guess it may be a capacitor. Many stereo-philes install them to help manage battery and amp drain from high end sound systems. Does this sound like anything your car may be running?

It's a noise suppression capacitor.

Used to help get rid of "alternator whine" in the stereo.

STILL only 12-14 volts, and like a auto battery, you need a sweaty grip/arm on a wrench and lean hard on ground/chassis to get 'bit' and at that it's only a tingle.....

HOW SOME EVER, do NOT try that with household voltages......

Um...the caps in old flash cubes have killed people.... I do know they will give a really painful bite, people would make zap guns out of old cameras,
I work on old vintage antique arcade stuff that has ones that are low volts but will bite the snot out of you, but ground both terminals with a screwdriver etc and it will zap off the volts it stores...I use a 12v bulb to drain them, .

Yeah- but they (xenon flash circuit in the camera) use an oscillator and 2 stages of transformers to raise the voltage to 1000v...

However this noise suppression cap might give you a small bite if you put it on your tongue.


Bob-

I also doubt if it would even be worth re-using -as it is probably deteriorated - and really is not doing a thing.
