they are polarized put in backwards they rupture or explode, fan spew acid in ones face, on as one did in 1978, blasted aluminum chunks of metal in to my leg.
(in our factory) today the cross (embossed) on top , cracks first, and lessens acid damage to PCB, (or so the theory goes)
I hope this fixes it. I hope no acid damage is there, even eats copper PC traces to GONE totally.
see this example
this is why they say some boards can not be fixed, or parts not sold now, as many are not.
some times the corner large cap comes off, and under there is a main power trace that is GONE for ever, unless using jumper wire trick.
see the + trace here ,I found it gone so 1 jumper top to bottom fixed this ECU. Good thing this a tracker on not Sammi as ECUs are sold for track/kicks.
