Mazda mx5 was jump started with terminals wrong way around! I replaced main 100amp fuse - engine now runs fine - problem is radio, lights, c locking and interior light don't work, all fuses are ok

Sounds (i can't know for sure unless i can test it) like a bad relay or a connection is broken. Have you checked underneath the hood in the fuse box in the engine bay?
