Brake light filament not working
Hey fellas, brand new to the forum here. I am having a few electrical issues with my new purchase (1970 Chevelle)
The left tail/brake light situation is weird, simply because power is getting to the rear light, but in a weird way. I've changed the bulb to no success, so it's something in the wiring. Ultimately, the bright filament isn't getting power. Of note, everything else works fine (front flasher, running lights, etc) Here's the situation on the rear left side:
Headlight switch off: brake pedal activates tail light filament (dim)
Headlight switch on: tail light is normal (dim), but when I hit the brake pedal, there is no light (neither filament)
Both turn signals work, but again, weird situation on the left
Headlight switch on OR off: tail light flashes (dim) instead of brake light filament
I checked wires, and the yellow wire on the left was scuffed, but still intact. I'm confused as to why the bright filament isn't getting power, but the turn signal is still working, but on the dim filament. Is a wire crossed somewhere? The right has no issues.
Pretty basic wiring, but I'm stumped.
