1972 satellite brake light issues

[dgie]

I am having this problem. I bought the car and found that had major corrosion on the light sockets in all the rear lights. I replaced the light sockets with new ones that I bought at orielley's. They are to fit a Ford and have 3 wires coming out of the back, one being ground, they are to hold a 1157 bulb and fit with little modification into the light socket openings in the taillight buckets, so I used them. I have this problem though. I have no brake lights I pulled the 2 wires from the brake switch at the peddle and made sure that one was hot, it was. I followed the other wire up into the steering column of all places?     I then put in a wire to jumper across the two wires simulating me pressing on the brake and the side marker lights and the instrument cluster light comes on. Anyone know what might be going on here??

maybe you are grounding the wrong wire on sockets

[dgie]

wondering why the brake light wire from the swich at the brake peddle is going into the column

[Nacho-RT74]

because brake signal is cut when you put blinkers ( turn or hazzard ), rerouting the "brake" wires from the flashers source to change the function.

Is different from 2nd gens. On earliers you still have brakes with blinkers... on laters, you lost the brakes function with blinkers

[dgie]

I see, so would you say that my problem is in the back by the lights and not in front with the column?

[Nacho-RT74]

yeah... PROBABLY wrong linked wire at sockets. Do you have multitester ?

[dgie]

I will check there. I have 2 lights 1157 at the top under the red lens and an 1156 at the bottom with the clear lens. At a stop what light should blink? outer, inner? both ?

[dgie]

I do have a multi tester

[Nacho-RT74]

both reds are 1157. Two filaments Two contacts. Socket must have three wires... ground, parking and brakes/blinkers. both work with parking and both with blinkers

reverse is 1156, one filament one contact. Socket two wires... ground and filament.

be sure the bigger filament meets with brakes/blinkers. Is the high wats one, more shine/powerfull bright.

multitester... check with continuity function which wire is the socket chassis to be sure you are linking the ground with ground.

I'm trying to remember, but on tail harnes:
black is ground
gray is parking
brown is one side blinker
green other side blinker
Violet reverse

both green and brown serve to brakes

[dgie]

I have a total of 6 going back to the back along the door jam, 1 is for gas tank sender, 1 is for trunk light,  then I have the following. green, purple, brown, black, gray (ground) , not sure if the wires colors are correct in my car, not sure what went on before me.

when I tested them  it looked like this:
left blinker  = green
purple = backup
brown  = right blinker
Black  = parking light
Gray  = ground mounted by a screw on trunk pillar
no brake light and only one filiment or the other comes on in the 1157's depending how I switch the wires around

how?

[Nacho-RT74]

do you remembers when I told you inside column brakes signal is rerouted ?

when you have running normal, the brake wire enters to column and then is routed to browm and green rear wires.

when you put left or right turn signal ( brown or green ), turning switch cuts one side or another side from the brakes pedal signal, keeping the other linked to the brakes function.

when you put hazzards, then white wire signal is completely cut and then wire coming from hazzard flasher is the one that feeds both rear green and brown wires.

For example white wire is the wire coming from brakes pedal switch and as far I can recall now red is the one coming from turning signal and pink is the source from hazzard flasher. When you put left turning signal what I remember is green wire, white wire keeps feeding the brown wire to the right side keepning teh brakes function only on that side, for a while red wire coming from turning flasher then is the one that will feed the left side tunring function, making it blinks. Same of course to the other side.

When you put hazzard, switch inside column cuts COMPLETELLY the white wire coming from brake and then both sides ( green and brown ) are feeded by the pink whire coming from hazzards flasher. then you lost the brakes function

front turning signasl are light green and tan. Of course they are not linked to brakes wire, but of course flasher signal is rerouted also to fronts.

when you don't have any blinker turning on, of course you have NORMALLY linked white wire to rear brown and green wires.

[dgie]

whats your best guess with the wires I have listed, by function they prvide as to what goes where? I am assuming that I will have to just move them arround to the different fillamaments until I get the right combination.

[Nacho-RT74]

with wrong ground linked on to sockets you can get a feedback that would make turn on rest of lights when you were making the positive jumping.

anyway is just a guess, but I think the most probably one

[dgie]

I will check it out, thanks for your help. I will keep you posted.

[Nacho-RT74]

Black  = parking light
Gray  = ground mounted by a screw on trunk pillar

you are right on this... I was wrong and posted inverted... my memory failed

[dgie]

here is an update on the problem and what I found was wrong. I ran a voltage test on one of the leads that was going to the right blinker and found that there was no voltage. I bought a new blinker switch from Year One and installed it that solved the problem. I only have one problem remaining, when I put the car in reverse, the reverse light comes on fine, but when I go back to park it does not go off. I have to go to drive or somewhere past reverse then back to park and it goes off. I am assuming that something may be out of adjustment. I am assuming that the reverse switch is working, but not sure if it is mounted on the transmission or somewhere on the column. Whats yall's thoughts on this 

[Nacho-RT74]

Since 69 the NSS is the one that controls the back up lamp too. So that problem could it be damaged NSS or internal tranny cam whant makes it work.

[dgie]

Thanks Nacho, I will check it out, hopefully it does not go as deep as inside the tranny if so $$$ I would think there might be some sort of adjustment  not sure though
