that is correct, if it's just the ign switch then you should still have dome light, headlights and some other things. Honestly it sounds like there was some damage from whatever accident it was in. You will have to go through and check (with a meter) power connections throughout til you can find the bad spot. more than likely it's a connection going in to the fuse box under the hood would be my guess. electrical troubleshooting is time consuming and can be a pain, but is worth it.
