I will like to get some help for u guy I was setting my car and I unplugged the battery and I send some friend to plugged again and he put backwards and now it don't turn nothing on just the emergency lights... help please and it's a ap1 2001 I appreciate ur help thank u

 

Likely only the largest main fuse is blown.

 

Which one u think

 

Where is that one on a ap1

 

It's in the fuse box right next to the battery, it's rated at 100A.

 

I bought the car boosted and the battery its in the trunk and the fuse box it's gone I been traying to look for it but I couldn't find it any ideas

 

Oh it's probably been relocated then, if haven't been able to find it it might be in the inner fender wheel area.
