The Blinkers aren't blinking. When the lever goes up or down the lights go on but they don't blink. If you put the flashers on the lights blink.
If you know what to do or have any ideas that would be great

Thamks,

Usually when I have trouble with lights on a car the fault is in the ground connections. Weird things happen when the ground connections are iffy. Try cleaning the sockets and their connections to the body and cleaning (or replacing) the bulb's base & contacts.

Are you sure all the filaments are functioning? Some (most? all?) of the signal bulbs are dual filament - one for 'parking lights' and a brighter one for the turn signals. And most turn signal flashers need to have certain amount of total resistance to make the blinking part blink. Maybe you have one filament out on each side so that there isn't enough resistance for the turn signals to blink but the hazards will blink because the total resistance meets the required level. (either that or I don't know what I'm talking about...)

Replaced bulbs, hazards come on and flash, but turn signals just stay on bright. Any other ideas. If I understand correctly.
1. Power from the battery goes to fuse box.
2. Then to flasher.
3. Then to hazard switch
4. From Haxard switch to switch on colum
5. From Colum to out side lights.

I suggest you send a PM to PapaJam - ask him for a copy of the excellent color-coded wire diagrams he makes. He'll email you some .pdf files that will make understanding Alfa wiring much, much easier.

From my perusal of the wire diagram, it appears that power goes from the battery to the starter then to the junction box on the left inner fender then to the fuse box. Fuse 5 protects the turn signals (among a few other circuits).

I can't figure out why the hazards work but the turn signal don't. But then my experience with things electrical is based mainly on the smoke theory of electricity. So, unless the smoke has escaped from something it seems like it should work...

Below is a snip from PapaJam's wire diagrams. Maybe you can figure it out...

Thanks for the diagram it looks different than the wiring diagram in my manual. If I understand
1. red from fuse 5 to termainal +
2. terminal - black to fuse box
3. terminal p, blue with a black stip to cluster
4. terminal L, (2) whites with black strip (1) to hazard switch and (2) to turn signal switch.

I hpoe this is correct, Thanks for the diagram and I will e-mail papajam

There is a relay that could be the issue. Check manual for which one, but that was the problem with my Spider when the lights didn't blink.

mine was grounds when that happened.Same thing...flashers worked but signals were a no go,I think it was the one right up the front corner in the engine bay.I cleaned every ground I could get at on that car and it cured many problems on my first purchase of an Alfa.

Everyone here kept bringing me back to the same fix and low and behold that is what it was!!!

Very good luck to you....and I hope you find the problem.

Since the turn signal bulbs light up bright with the turn signal switch engaged, this would seem to rule out the power supply, grounds, turn signal switch and the bulbs. This leaves the flasher. If it is the flasher, the probable cause is the internal thermal unit is not heating up enough to open the circuit (turn off the lights) under the relatively light load of two bulbs but there is sufficient current flow to switch the circuit with a four bulb load.

I'd replace the flasher.

Went to check the flasher as outlinned above. Before I pulled the flaser I wanted to see where the white/black wire connected to. It went form the flasher to another blank post with nothing connected to it. therefore the turn signal had no power from the flasher.
My probelm then was I had power at the turn signals but where was it coming form
I trased the black wire form the turn signal switch into the fuse box.
THE BLACK WIRE WAS CONNECTED TO A RED HOT WIRE.
I REMOVED THE BLACK WIRE FROM THE RED HOT, AND CONNECTED IT TO THE BLACK/WHITE OUT OF FLASHER AND EVERYTHING WORKED.

Thanks to everyone for your help. could not put car back together with out everyone. As a side note yesterday the car would not start no spark. Took out Bosch l-Jetronic fuel tune up. tested flywheel sensors as outlined, top sensor dead. I had a extra sensor put it in and the car ran great. Made me want to fix the turn signals. This is a great article and everyone should copy and use. Thanks again to everyone. I am now on to fix the slow moving windsheild wipers. I hope there are treads to help.
