Not Ranked
Thanks for the look at my issue:
The taillights are the twin over-and-under round ones, and the brake light is the "bright" filament in the lower (1157 bulb) one. It is the same filament used for the turn signal light.
This problem is new. The car was built in 1992 and has always had working lights. There has been no damage to the car that would clearly cause an open in the circuit and no wires hang or are obviously subject to pulling or damage. Anything is possible, though, and I rule out nothing at this time.
I'll check the continuity from the low side of the pedal switch to the bulb socket, but I think I'll find that is an open.
The ground to these sockets seems OK since the turn light works (same filament, same bulb as the stop lights) and the running lights work on these sockets as well (same bulb, "dim" filament). The ground is the actual socket portion, so I think if the ground is OK for those functions, then it should be OK for the stop light as well.
The column I am using is from something like a 59 GM bob-nose truck (or something like that). The turn signal is the one that is a part of that column as is the hazard switch. The turn signal turns the "bright" filament on-off when the brake is depressed as well as when the brake is not depressed, so I think it is OK. The hazard switch runs the fron hazard lights, so I think it is OK also, but things may be more complicated there - I am just not familiar with the circuit diagram for the interactive devices (brake, turn, and hazard lights).
I am still looking for something common between the hazards and the brake circuits as my biggest bang for the buck.
BTW, there are no schematics for this car, it was built as a you-build-it in the earlier days than now. The fuse box is a "Dr. K's" brand and not as nice as the ones you can get now. The wiring is black tape wrapped from one end to the other and is really a pain to get into. On the plus side, all connections are soldered and shrink-wrapped and the wire is of a good quality.
I really think there is some device failed here rather than a wire that is broken (just a hunch).
Thanks a bunch for looking at my proble!!!!
