dash light ground problem?

[cheatham]

Well, reading previous posts about dash lights not working because of a grounding problem I took my dash out and am trying to get the lights to work. While it was out I have replaced the headlight switch because the riostat (spring) was messed up. I was curious if that would fix it but it didn't.

You all have said there is a ground to the dash or frame somewhere, but tracing back the wiring harness, I don't see one. Any help with what I should do from here would be appreciated.

Thanks,
Jack
