Blinker problems

[kelton]

The blinkers on my 1970 Ford F-250 Camper Special have gone out. None of the four outside lights come on but the relay clicks inside the Cab. The dash board turn signal lights don't come on also. The Hazard light switch works and the 4 outside lights come on but only one of the lights on the dash board works. Any ideas what might be the problem? I would like to fix the turn signals ASAP. Thank you for the help. Kelton

Have you tried replacing the turn signal fuse under the dash? It is a little metal cup looking thing that mounts to the dash support I think.

First thank you for the help. Could someone plz help me a little by highlighting the wire in the diagram from the flasher relay to were i hooks in with the hazard flashers so I can just replace the whole thing. I have been slowly re doing my whole harness. Thanks again kelton.

in this diagram http://www.fordification.com/tech/wirin ... master.jpg wire number 383 gives power to the hazard flasher can. from the can it goes into the hazard switch. then out to both front lights. and to the turn signal switch via wire number 810A. then through the turn signal switch and out to the lights at the rear through the brake light wire number 285 i think . which should be brown. your problem probably is in the turn signal switch. and how good it contacts the contacts inside of the switch.

Would this still be a problem in the turn signal relay clicks when activated?

[fordman]

it has to be in the wiring someplace. i only posted how and where the wires ran that you asked about. as far as the pilot lights in the dahs not working when the blinkers are turned on means that power isnt getting from the flasher can or tss. to the pilot lights in the dash or out to the blinkers. so that again points me to look at the column wiring plug for the blinkers to see if they have power going out and into the main harness.

[kelton]

How do I test the tss ? And also how would I remove it to work on it. Thank you

[fordman]

my mistake. i think i gave out the wrong info. please read this which i just doen for another member that is having similar problems. how ever i have changed the link from his year to your year of diagram.

for a 70 i looked at this diagram. http://www.fordification.com/tech/wirin ... master.jpg
the power for the blinker flasher comes from the fuse box via wire number 950. and into the wiper switch. from the wiper switch wire number 8 supplies power up to the flasher can for the turn signals. through wire number 44 which goes into the turn signal switch. from the switch they go out to the lights. so if nothing at the flasher can go back to the wiper switch and then back to the fuse box. it could even be a bad connection on the back of the fuse box with the wire and the terminal that holds the wire.

[kelton]

That might be the problem because I have been having trouble with the washer pump recently and now it acts like its not getting enough power so I will pull the fuse box and clean everything up from there. How much power should I be getting from the fuse box? 12 volts I would think? Thanks for the help.

[fordman]

yes 12 volts. it could be a loose connection on the plug to the wiper switch too.

[kelton]

The relay stop clicking this more on my way to school. Could this be anymore help with what the problem is? I have not changed anything yet as I have been waiting for the weekend to start tearing into everything. thanks

[fordman]

i would start checking things out. it may have now burned out the flasher.

[kelton]

While checking all wire I replaced a dash light for the turn signals. To test the lights I switched the emergency can with the flasher can. And Bam I have turn signals .... I will be buying a new flasher can tomorrow.
