Stuck brake light...short?

just a quick question regarding the brake lights on my 69. When I turn the key to "on" the brake lights are on. I replaced the brake light switch--still stuck. Notably, when I unplugged the switch, and turned the key to "on", the brake lights still went on. Is there likely a short somewhere doing this?

Re: Stuck brake light...short?

Sounds like a short alright. They can be tough to track, but that's what you will have to do.
I'm not positive off hand how the circuit works, but I believe the brake switch 'makes' the circuit so I would look at the wiring starting in that area.
Good luck with it!

Damn, looks like I'll be taking it to a shop. I thinking tracking down a short is above my pay grade. Thx

Re: Stuck brake light...short?

I definitely encourage you to track it yourself, the wiring on these old cars is pretty simple and when you come to the issue it will likely be obvious.
I hate tracing stuff like this as well so I understand, but the more work and digging around you do on your car the better you will know it, and you will save a fortune doing it yourself.
I'm sure guys on here can help you through it, it's not hard. Give it a shot at least before taking it in.

Re: Stuck brake light...short?

Don't give up. The line (white wire from brake switch) is tied in to the turn signal switch in the column so it's probably either in there or the turn signal relay.
Try all the functions and make sure they work right.
Key off, hit the brakes and make sure they work.
Key off, pull the hazard flasher and make sure it works right.
Key on, pull the turn signal relay out and see if they go out.
Key on, try the turn signals to see if they operate right.

You're right, I should try. To be honest, I don't even own a test lamp. Total neophyte. Hate to sound dumb, but how do I start (aside from purchasing a test lamp)?

Steiner; so if the brake lights don't work with key off (which I'm pretty sure was the case) what does that mean?

Re: Stuck brake light...short?

You mean if you pressed the brake pedal they didn't come on?

Right, you said "Key off, hit the brakes and make sure they work." So if they don't...?
