Had a great weekend at the bay ,and now I plug in one of my boats and the caps are sparking and popping ,so I pulled the ESC ,I have a castle cap bank and BEC, I was getting ready to remove them and install on anouther ESC ,but wanted to ask if it’s possible to change the stock caps on the sea king 180 ESC,it doesn’t really look like it and I haven’t plugged it back in since I pulled it out of the boat ,it was really getting ready to spark up,didn’t want to cause more damage ,help anyone ,thanks ,
