Wasn’t sure where else to post this. I accidentally hooked up my jumper cables backwards. Will no longer start. I get dash indicators and headlights but that’s it. No radio or nothing. Will not even click when I turn the key. I have checked all the fuses and they are fine so I’m guessing I must have blown a relay. But I’m not even sure where to start checking or if I missed something. Can’t find any specific diagram for the relays. Any help would be greatly appreciated.
