lights???

[fordsforme]

hi new member and new bird owner also. i can't most of the lights to work .the low high beams work and the rear tail lights come on for park lights but no brake lights ,no signal, no interior lights either.only had the car for 3 days first tbird i have owned . its a 66 hard top with a 69 thunderjet 429 under the hood originaly a 390 car, has a slipping c6 .its got some issues but not a bit rusty, and its all there. anyone no where to start with the lights? thanks will post some pics as soon as i figure out how

Check the ground wires on each of the lights. Also remove socketed bulbs and check for rust in sockets. If so clean and then use test light or good known bulb to test. Headlight switch may also be bad or internal contacts dirty. I assume you checked the fuses as well. Could also be a filament in dual filament bulb burned out. These are all common first things to check.

66 tibrd lights

i have been messing with the lights with no luck yet.i noticed that the steering column is lose ,i can hold the steering wheel and shake it a little and the whole thing moves around any ideas?

 

[tbird5866]

I hope you know that the brake lights and turn signals are not connected to the headlights or headlight switch. So, you are facing two different problems. Lots of questions need answers. Do you have power to the brake light switch? Do you have power to the turn signal switch? Have you checked the plugs in the trunk at the wrapped turn signal package behind the rear seat? Do you have power back there? "the low high beams work'?? what does that mean? Do you have tools to check the electrical system? Like a volt-ohm meter?

the car is a 66 .when i pull the light switch to park position the only lights that are on are the rear tail lights,when i pull it all the way out to the head light position the head lights come on, the dimmer switch works from high to low beam,no front park lights,no turn signals,and when i press the brake pedal no brake lights,the only thing that works in the interior is the battery volt guage.i hope this is a little clearer .. now where would be the best place to start to getting the lights going again? yes i have a meter to check ohms ect with .just needing a starting point cause this car and tbirds are new to me but i have other fords they just don't have as much wiring ... thanks

First if you have electrical problems, You should invest in an wiring diagram. I think even the shop manual has that in the back of the book. Like Harely said are you getting juice tothe brake light switch, Parking lamps also? They sell kits to repair your steering columm, The bushings/bearings are shot. This would be a good time to check out your turn signal switch since the steering wheel has to come off. Loose steering columm may cause the car to jump out of park!! as far as the guages not working, The guages that do not work are controlled by the cvr which may be bad. Check all your fuses with your meter from prong to prong. Sometimes the fuses are good but contact to prong is bad.

ok thanks i will start on this as soon as the weather breaks there is about 12 to 13 inches of snow outside right now i will post any progress

 

[tbird5866]

I have emptied my "inbox" so that private messages can be accepted.
I trust you are aware that the battery meter instrument shows amperes, not volts.
There is an instrument voltage regulator that controls readings for the oil pressure, the fuel quantity and the temperature. It is mounted on the back of the speedometer.

 

[fordsforme]

see im glad we have crossed paths cause i am not aware of these things until you mentioned them.but im learning i will start troubleshooting as soon as the snow melts . thanks harley

Hey Fordsforme, I was curious if you found the problem. Ive had my 65 for a about a month now and 3 days ago my turn signal and brake lights quit working. So I might have the same problem you had. Thanks.

 

[tbird5866]

Eric: I think you should tackle your two problems one at a time. Follow your brake light power from the fuse box to the brake light switch to the relay in the luggage compartment ( which could be the problem). Make sure you have battery power to the relay. Then the circuit goes into the turn signal relay (in the wrapped package). There the brake light circuit joins the turn signal circuit. Check power to the turn signal flasher (sequencer) also in the wrapped package. Do you have a wiring diagram? I believe you will need one!!

 

[Eric the Barber]

I have the shop manual but when it comes to wiring, its not as detailed. I think I might just have a bad ground somewhere because when I flip my turn signals it sparks in my steering column. So I took off the steering wheel to see if it was just a loose wire in there, but they all look good. And when I hit my brakes I can hear a click coming from the package in the trunk.

 

[tbird5866]

The brake light relay may "click", but not be supplying current to the turn signal relay or the turn signal relay may need to be replaced.

 

[Eric the Barber]

Its my sequencer. I think it was originally my signal relay plug. It came loose and when I pushed back on, my brake lights worked, But my turn signals still dont. I think when it came loose in might have shorted out the sequencer. So I opened the sequencer, cleaned and lubricated it. Then I spun the shaft a little to work in the lube. Then my brake lights didnt work again and my charge indicator started bouncing to D. So I spun it back to where it was and my break lights worked again. And whenever I have my breaks pressed and I try the turn signals, the sequencer makes a crazy noise. So Im going to try it again tomorrow to see if the lube works and if not, Ill get a new one. But if anyone knows how to fix it without buying a new one, please let me know.

 

[tbird5866]

It's a little complicated, isn't it? You say the sequencer make a "crazy" noise when you've applied the BRAKES.. What about when the BRAKES are not applied? If you decide to get a new flasher/sequencer, I can help with that. I have a new one for sale. I'm really lost re your remarks about spinning the shaft (of the sequencer?) and turning it back where it was. Since the sequencer has no effect on the BRAKE light circuit, it makes no sense. I'll watch for more info.

 

[Eric the Barber]

It doesnt make the noise if the brakes aren't applied. But they dont work. The brake lights only work if the bottom gold prong in the sequencer is being pressed by the white spinning shaft (in the sequencer). And if the prong is not being pressed the wires to the signal relay only get power in small blasts about 5 seconds apart.

 

[tbird5866]

Looks like you have some serious electrical inspecting to do. Get the wiring diagram out!

 

[Eric the Barber]

Alright so Ive been reading the crap out of the shop book. Ive figured out why the brakes only work when the bottom prong is depressed, but the shaft still doesnt spin. All the wires in the sequential are getting power. The wires going to my relay are getting power, but the wire plug that hooks into the relay has a melted corner which Ive read that means its malfunctioned.

Which brought me to my next problem when I looked for a new relay for the car, Ive found 2 different parts under "turn signal relay". One is the little silver box with the melted plug (which I believe is the relay) Then the black board to the right of it w/ all the red, green and yellow wires. I checked the wires on the black board and theyre not getting any power to them. So my questions at the moment is, is the silver box the relay? and if it is, what is the black board? and does the current go from the sequencer to silver box to black board? Or black board to silver box to sequencer? I know these are dumb questions. I just dont want to buy a part that I dont need. When it comes to engines and body, Im fine, but wiring is a different world to me. Thanks for any help.

Eric, I hope this picture helps.
I no longer have this system in the car, I replaced it with the much better electronic system.

Thanks Bob that did help. Did you go to the Mustang sequential light unit?

Looking at the picture, its my turn signal relay that is getting no power. But also after looking at the pic, you have the flasher relay and the Brake relay and they both look the same. I only have 3 things back there. Im guessing its the sequential, Brake relay (since it clicks when I hit the brake and if the plug comes loose the break lights dont work), then signal relay. Heres a pic of what Im looking at. Im still curious which way the current goes. From sequential to signal relay, or signal relay to sequential.
