Checked the fuse and have power to the brake switch at the pedal. Power from the switch at the pedal is also present when the pedal is depressed.

The ground at the bulb is good as the bulb lights when turn signal and running light is used. The ground goes from the socket to the "threads" on the bulb and is common between all filaments (one ground for the entire bulb). Also double checked resistance from bulb socket to batt neg and have <.5 ohm.

Thanks very much all for replies.

Will be out of town til Fri night when I will be able to try to separate front from back. I think this will help. Will also look at wiring from switch thru column, trurn signal hazards etc. Also like the check for continuity from switch to bulb contact. Also like the idea of depressing brake and using turn signal (I think I did this and the signal worked, but will double check).

Will return to this thread Monday with progress.

Thanks again.
