Default Brake lights turn off, when either blinker is turned on!

Basically, the title says it all.

If you activate the brake lights and they light up, then turn on either blinker, both brake lights go out.

Can't imagine this is correct, but I've made assumptions before and been incorrect.

So, i'm sure the correct way is brake light on, turn signal for left turned on, brake light goes out on left side and becomes blinker, while the right side stays bright. For the age of technology, is this correct?

Then, steps to troubleshoot if anybody has been down this road before. I figure its the blinker, and the contacts are doing something funky.

It should work as you describe. It sounds like dirty contacts in your turn signal switch. I would try moving the shift lever up and down a few times to see if it fixes it. If not you'll probably have to take it out and do a visual inspection. I would also check under the steering column and make sure all the connectors are tight and not corroded.

Connections are tight, John. Remember, turn signals interrupt brake lights. He has a bad turn signal switch plate. I haven't seen his but I can imagine too much current messed up the switch.

The good news is, I'm sure many of our vendors carry that switch.

Hey, when you pull the old switch out, attach a pull wire. It will make the new installation easy. - Dave

My '66 has the motorized sequential turn signal module. It's like a child's music box. I took mine apart to repair it. The mechanism can get rusty over time such that the relays don't make good contact.

Take off the metal cover by bending back the tabs, clean the unit, re-solder any loose wires or cracked solder joints, light oil any movable parts.

When reassembling, seal the metal cover with RTV to keep out moisture. When reinstalling make sure there's a good ground to the body.

Hope that helps.

Cheers,

Brian has a '64 so he doesn't have the sequential lights.

Correct, that its a 64. No sequential turn signals. I also agree all the connectors and wires would be good, due to they work independent of each other. So, that leads me back to the common area, turn signal switch area.

Now on to bad turn signal switch plate. Quick google looks like a wire harness and mechanism .

Is this the device you speak of?
