Just on the odd chance that the switch is still the culprit, try checking
the resistance between each of the two switch contacts and ground (battery
disconnected). If there was an internal short in the switch to ground, it
could cause the symptoms you describe. Since the tail lamps aren't fused, it
could cause the lights to go out when the brakes are applied.
Again, it's a long shot, but worth a 30 second test.

Subject: TD brake light..more info
More info...
I tried short circuiting the switch and still got nothing on the brake
lights. I was under the impression if the switch was bad the brakes would
light up . (yes- the ignition was on) I determined the wire that went up
to the engine area from the switch, went to the turn signal box (turn
signals are fine).
My confusion is that when the brake is depressed, the Ohm reading between
the 2 contact points of the brake switch, drops to 0 - Signifying it is
working correctly.??? The volt meter however shows + voltage in the hot
wire contact (other tester tip is grounded to the frame) before the brake is
depressed, but drops to 0 after the brakes are depressed. HUH??? I've
checked/tested the ground in the driver's rear frame and it seems to be ok.
Curious - are the running lights and the turn signals grounded separately
from the brakes?? Just a bad switch?? I'm done for today. Way too much
time spent on it already. Otherwise car is running great.
