Goodday engineers in d house.
Am having problem wit my car wic is a Mazda 6 sports sedan.
I went to assist a broda who was havin issues wit his car wit my battery only for him to fix the battery backward ie negative to positive... I notice some sparks so I rushed nd removed the head to stop d damage.... Long story short, now my audio is not coming on, my AC comes on its own wen I start d car, I can't lock the doors using the car remote, the door sign warning light and security light dat use to blink don't anymore. I av checked the fuse box for any blown fuse but just one wic I av changed but still no luck. But the car start cause it seems the main fuse was blown b4 and d fuse was joined by a wire.

I just noticed dis too... Wit the ignition and engine off
