I had some bad cap leakage on one of my Eprom ecu's. Once I removed all three of the caps, I noticed that "C14" (surface mounted capacitor I assume) is fried and cracked in half from all the damage from the leaking acid from old caps.
Anyways, I have some old non working non eprom ecu's laying around, (which also have damaged "C14"'s as well, but I noticed that there are tons of other exact same looking surface mounted caps around other areas of the board. I desoldered "C20" off of one of the non working old boards and re-soldered it back into the C14 position on the eprom board. I fixed up a couple corrosion areas around the capacitor contact pads, re-soldered the caps into place along with the main diode I removed to access the C14, and everything seems to be running OK again.
Now my question is... Is it Ok to use any of the "c14, c12, c20 etc etc" to swap into place of the damaged surface mount caps?
and also is the anywhere to buy those style small tiny surface mount capacitors anywhere? cant really seem to find much info on it reguarding DSM ecu's anyways. Just more "generic" circuit board youtube videos etc.
Thanks!
