I recently bought a car radio and made a stupid mistake when I connected the radio to the car.
Apparently I reversed the polarity on the radio which made the radio go poof and smell awful.
They still look flat to me, so I can't tell if can expect them to work or not because all the surface mounted capacitors with this size (8*12mm) on this board have this cross visible.
I don't have an oscilloscope as I have read that this could help determine if the capacitors are busted or not without removing them from the circuit.
I have searched the internet for examples of busted aluminum surface mounted capacitors, but I haven't been able to find examples to compare with.
So my question is, can I expect these capacitors to still be functional?
I'm hoping I can get the radio working again by replacing the busted capacitor(s). Hoping this is the only damage made to the circuit.
** EDIT ** I really don't understand why this is a bad question?
