Hey everyone so I changed the battery on my 95 Rx7 FD and didn’t realize that I switched the terminals. Now the car won’t start, non of the lights or other electrical accessories work but the car does crank. I checked the 3 fuse boxes that are in the engine bay and all of the fuses are intact.

Anyone have any ideas?

 

Double check the 120a main fuse under the hood. Check EGI and B2 as well

 

it does look weird, I’ll replace it and see what happens

 

If not that, I'd recheck the cabin fuses, then the ignition switch.

 

Typically the 120A main fuse blows when you hook terminals up backwards or attempt to jump the battery backwards.
