64 ford f250 brake light issues

we have a 64 ford f250 with the 292 in it. We have no brake lights and that's after we have replaced bulbs and brake light switch. Any ideas on what this may be? we have tail lights and turn signals and wires were good all the way from the firewall back to the rear lamps.

You need to be sure you are getting power to the brake switch. The other aspect is that the brake switch is before the turn signal switch in the circuit, so on occasion the turn signal can actually cause the brake lights to not work. You simply will have to keep checking the circuit until you get to where there is power. Once you find power, you can determine where it is being cut off. The brake switch should always have power to it.
 
Grounds.

Hello and good afternoon.

Excellent advice from others; perhaps there is a "ground" issue. Bad grounds can wreck havoc on anything electrical.

Just food for thought.

Postscript: Hold the bulbs with a rag (should never touch a bulb without a rag or gloves-oils in the human skin will shorten the life of the bulb) and rub the contact on the concrete to clean it. You would be surprised at how many bulbs were thrown in the trash that were good!

The rag or glove thing is only applicable to halogen lamps, standard ones do not generate enough heat for the envelope to be affected...also concrete may remove a great deal of the solder on the contact...emery cloth or some fine grit sandpaper would be safer.

I would have to politely disagree with you. The skin releases oils that when come in contact with metal for example will begin to rust (I was a Machinist) and your 1018 and 1020 series steel for example would begin to rust the folowing morning after machining. This applies to all electrical bulbs as well; the oils that is.

I am old school so why use something that costs money (sandpaper) when the ground is FREE?

I will agree with the metal, but not the envelope. Ground is free absolutely...whatever floats your boat :)

Well, I have salvaged many a GE1153 and GE1157 for over 45 years and it was then that I was taught not to touch them bare-handed.

Moreover, I do not own a boat.

If the lights were non-functional, a ground or connection problem at the light itself could be suspect, but since the turn signal and brake light signal are one and the same at the lights, that is taken out of consideration. That leads back to turn signal switch and before, as again, the turn signal switch has been shown to supply power to the tail lights. The power is supplied to the brake switch, then the brake switch applies power to a circuit in the turn signal switch so that the turn signal will still flash even when the brakes are applied. So that means the problem is either in the turn signal switch ore before.

Doon, I know you mean well, but please do not assume that we are not being helpful. The problem with text is it does not always convey attitude or demeanor correctly. Many of us have also been doing these kinds of things for years. Many forums are filled with attitude and such, but I hope you have found this one is not.

No worries Fellpro.

Hello and good morning "Mighty MO" Members!

Fellro, no offense taken at all it is just what I was taught, nothing more. Please do not feel that you were abrasive or negative in any way.

Hey, if we cannot agree to disagree what is the point? I went to bed early last night and it felt good to sleep for 6 hours(insomnia) and now I am full of vitality and raring to go.

Fellro, now let me see, you are an Electrician and I was also a Plumber for 20 years so together we could make some good coin!

On a humerous note, the Electricians and the Plumbers would battle as the Plumber should actually be scheduled first behind the Framers as the Pipe and tubing are rigid(rough plumbing) and the Electricians would try to sneak in ahead of us! Hey now wait a minute!

Construction was very lucrative but as a Machinist and a Plumber I am now a member of the BBC. The Bad Back Club. How about you?

I am not hijacking this thread it is just that you and others have given great advice/suggestions regarding the brake lights.

Take care and Godspeed!

Boon

Negative Boon, Duncan (DNFXDLI) is the the electrician, I have an automotive repair technology degree as well as a mechanical engineering degree. On top of that, I have wrenched one quite a few variations of vehicles over the last 25 or so years. I speak from experience on most of what I reply on. I actually have been going through the circuit by memory, but they really are pretty simple once you know how it all works. I had one turn signal switch cause the brake light to only work on one side, which was the side the turn signal had last been set to. I have had plenty of them stop the brake light signal all together. Only if the turn signal was totally independent of the brake light circuit could it not be possibly to blame. Since the original poster stated his turn signals work, that eliminates even looking past the turn signal switch to me.

Hello and good morning Fellro.

A misunderstanding in that I was referring to MY TRUCK regarding the turn indicator.

The left turn indicator will not shut off even after completing the turn? I have to manually turn it off.

I apologize for not being clear.
