All Rear Lights out on 67 Barracuda

Hi all, another electrical issue has come to my attention.

All of my rear lights have quit working, breaks, indicator, running and backup.

the first thing I did was check the fuse (which was bad) and replaced it with a new on. tried the lights, No work.

Checked the fuse again and it was broken. meaning I have a short somewhere?

I have checked to see if there is any exposed wire where I can (by the tail lights, near the plug at the front, and along the bottom of the door, and nothing that I could see that was obvious.

I have an ohms reader, but i'm not exactly sure how to read it and if that is something I need to use to find the solution.


Any information is appreciated.

Thanks in advance!
