LRP SXX Ver 2 - fried? capacitor question

[martgifford]

Desperately need some advice. My friend in a hurry put positive amd negative around the wrong way tHrough my esc. It blew the battery connectors of and melted a little of the Lipo. A guy at the track tested the battery and it ïs holding a charge. Now I tested the esc, and spark started flicking out of the connectors to the battery so I'm hesitant in running any current properly through it. Now is it blown? Could it be just a simple power cap? Can I tested it. Want t give it a try before I bin it (or sell on oople as used twice! )

Seriously though any suggestions to try and test or salvage it? I have asimoke volt meter if that helps but I need to know what to test

Thanks
