A short, or something else?

thanks everyone!

I didn't think to remove/inspect/clean the headlight switch. I will do that tonight.

For the bulb sockets at the pc board - I did remove, clean (deoxit worked great), and replace all of the bulbs - so it's very possible that I very stupidly knocked something loose. I hope I didn't break a pin.

Another thing I read was that the screws for the cluster can pierce the harness wires, so that'll be another thing I check.

67Dart27 - I think it was you who suggested (in another thread) to add a separate ground wire to dash frame for the pc board. A great suggestion and I plan to do this tonight.

I'm sure I'll find the problem, it will just bug the crap out of me until it's fixed!
