Question type: Maintenance & Repair

My husband tried to charge my battery caused major sparks and now my
electrical system is out...no radio,interior lights, back lights, blower wont work
nor power windows or locks will work.  Help please!
It isn't the battery. After that happened we bought a new one. So i figured he
blew a fuse, but which one?

Check inside the power distribution box for blown main fuses and any other system fuses. That’s usually what happens when a battery is connected backwards.

Mega fuse, bet you blew it with the sparks that flew. Cheap fix.

Thank you Tennisshoes and FJ4072 For your answers. I hope that it is only the mega fuse and nothing more. I will check it out, thanks again!
