1963 Falcon break light problem Sign In

had problem with break light staying on. tapped the switch on the master cylinder and out go the lights. push the break peddle and they work. then they went out again so I replaced the switch. running lights work and signals work but no break lights. I thought the break lights were using the same filament as the signal. is there a fuse for just the break function alone? or what MAY BE THE PROBLEM? PITA!!!

Kinda suggests plug to the switch on master isn't good since tapping on it made it work. Yes, same filament in rear bulb for directional,

I replaced the switch Tom still no light. I then did a jump on the wires to the switch to complete the connection manually no lights. so I will now have to trace the harness to find a break in the wire I think. I will try to order a wiring diagram from Max Antique Auto

Re: 1963 Falcon break light problem Sign In

? Just re read your first post and now more confused. What the heck is it doing again. You said you tapped on the switch and it worked didn't you?


TMK that "pressure" switch type would just be two wires and connecting them inside or disconnected right there depending on the pressure. No pressure no connection and so on.


That would mean if just the two wires there one is always hot (12v+) and the other on to lights thru a flasher no doubt and don't think this year had 4 way hazards at all to mess up the scene.


Pressure switch itself could be bad new or not and quit making that style not long after that car was new. I would use a plain test light to see or an ohm meter while someone pushed brake that it made the connection or not without the harness plug at all and again with it on back probing the switch.


It's plenty old enough for odd problems or intermittent ones but not much to this car to go wrong like that but wiring things are wiring things,

did not mean to confuse about the switch. what I did as a test was to connect the two wires of the together to bypass the switch as the switch would under peddle pressure. I will check the wires 12+ is on one side.

Think I got you. Yes - touching or jumping two wires together should make brake lights come on same as hitting the brake pedal. If no 12V+ at one wire there that's the problem first if they do not come on. Brake lights should work when car isn't on at all and no key in it. If nothing check fuse and fuse box area for troubles,

would the regulator be in any control of the lights? I checked all three fuses to find no problem with the fuses. on the switch wires one is 12+ the other goes to ground. this is getting old I may have to rewire the whole system the way it seems to be going. frustrated old fart here...

Re: 1963 Falcon break light problem Sign In

Seems you've had them working so not so suspicious of wires themselves yet. Test light if what you are using should be about all you need. At switch as master cylinder the 12v+ is there all the time which you found. Other side would read ground as it's trying to light the lights absorbing power so would show as a ground depending on how checked.


I should know exactly but this is old and changes came along soon after this model year mostly no more hydraulic switches. The ones that share a directional with a brake light run thru (I think) the flasher so one brake light stays lit while other can blink with brakes applied/on. That's where I think the trouble is.


Ordinarily I'd say swap a 4 way flasher for the directional but that doesn't apply here TMK no 4 way hazards in 1963? I look up parts to help and it shows a very common flasher still an in stock item! Looks like this if the pic shows..........

Probably under driver's side over pedals? Listen for it and by looks. Whack on it to see if it snaps out of this behavior or toss it OR if you have a pic your own salvage yard many are the same up to much much newer vehicles.


Some issues probably nothing to do with this is how these cars were equipped when new. They were offered with about nothing but a steering wheel and wheels on up. No two speed wipers, no back up lights, no radio, no washers for windshield, no power steering,brakes, no carpet (just a floor covering) so bare it's scary but can be nice and some had wires dangling where features would have been so they didn't make multiple wiring harnesses.


Advantage is the Mustang introduced the next model year was just about the exact platform and dash concepts plus much wiring of this car so odd ball things very well are the same if needed.


So back a bit on testing. Fuses should all be glass and fussy then and can only be worse now. Check for power with a test light at those in and out and on to wire. See if incandescent test light goes out or dims too much if an item is enabled as those pinch type holders for fuses could be quite weak messing up testing.


General: Wires are good usually. Connections and wiring insulation gives out. If bad enough new would be nice and there's isn't that much in the whole car! Availability unknown?


Join or check out a club for these cars. You may find info and parts (NOS) stuff = New Old Stock thru the clubs not even listed on web ads alone?


These cars were solid as unit body cars go the shape ended in 1963 was strong. Rust was it's worst enemy like any but this was better than average so if not about anything on this can be dealt with,
