I wasn't paying attention when hooking up my battery and rushed it, I accidentally reversed polarity and it honked I noticed and disconnected the battery I blew the 125A Main MIDI fuse replaced it but not my dash light and stuff will come on my radio wont and the car doesn't even try to crank just does nothing I was thinking maybe the main relay but not sure its a 2009 Mazda 6 GT any help would be amazing I've hit a wall.

 

Welcome to the forum

Asking twice same thread topic won't get anyone to help you faster?
Maybe slow down when working around anything electronic?
I suggest you recheck all the main fuses and relays again. But with the Battery properly disconnected. Also put the battery on a charger and charge to 12.50 + volts and have it load tested before using it and connecting it back up to your Mazda.
DO NOT ASSUME it is good because it is charged to 12.5+ volts..... You have already violated the battery so get it checked before you possibly cause expensive damage to your MAZDA!

 

I couldn't figure out how to remove one after posted two my bad

 

I understand but it makes you think about your thread topic.
