Hello everyone..

I have an electrical problem on my 1963 grand prix. The battery on my car was going dead after a few hours if left it connected so I always disconnected with a battery quick disconnect pole adapter, a few days ago I noticed that my brake lights were on all the time, so I replaced the original brake light switch on the brake pedal that did not fix it... I tested both cables to the stitch have ground signal..

Any ideas what to test next? Has anyone had this problem?

Thank you and have a great week!

Is there power on both sides of the switch with the button fully depressed?

Thank you SteveP

No power on either one both are ground, it may have been like that since I bought the car... just started driving it a couple of months ago after fixing everything. Maybe I have the wrong cables connected to the switch

If 1963 is the same as 1964 there are 2 single WHITE plugs. One has a PURPLE wire and one has a WHITE wire.

Thank you goat racer... My has the 2 white plugs and one white and one black both Negative but somehow the brake lights are on... I was looking online and appears that the white wire goes to the turn signal switch. I am not sure what is going on... I am going to look for the purple wire under my dash it maybe connected to another power source

Thanks again

Is it actually brake light, bright light?
Or tail light?

What happens when brake pedal is pushed?
Turn signal on?

Take a brake light bulb out then both and see what happens?

Also take the stop light fuse out and see what happens?
