I can’t really confirm that, sorry. But in theory this looks right. That switch puts power for the parking lamps and headlamps and then the stalk switch decides between the two.

Any chance you can jump the black/white turn signal power to the black wire on the switch and see if that solves the problem?

I assume the black wire on your switch has power when the key is on. It should enable the turn signals to work while the key is on, then headlamps and parking lights work when the switch is flipped? Maybe that will help narrow down where the hiccup is.
 
I have had them changed numerous times but I'll try again.
Latest thoughts are the turn wires should be separate from the lights on/off switch but if it looks like they interfere perhaps one wire at the sidelights is crossed meaning turn works fine with switch off but when on its mixing the circuits and dragging down?
Example is if one sidelight is flashing through sidelight circuit not turn circuit?
I'm gonna check all the sidelight connections later to make sure they're all the same ie turn/side/earth and ones not side/turn/earth.
 
Might of found something.
3 side bulbs are 2 filament 3 stalks.
1 side bulb is 2 filament 4 stalks.
Which is correct I'm thinking 3 stalks but not sure?

Just seen this on fiat site, looks like it's 4 stalks so I'm getting excited, off to buy some new bulbs.

Fitted new bulbs.
Ign on turns work.
Iight switch on lights work fine on stalk but turns don't.
Something is happening when I switch on light switch to affect turns.
Gonna have lights switch on and keep disconnecting lights wires at fuse box and see if turns will work.
 
Writing before I forget
diss white wire back of light switch
Ign on turns work
Light switch on
Turns work
Stalk
1 sidelights on turns work
2 no Headlights turns work
3 main beam turns work
 
Been on it again today, getting nowhere packing up.
Gonna remove all wires to fuse box and continuity check every wire from each light as it seems like one must be crossed.
Can anyone please confirm if main beam lights the upper or lower part of the headlamp as its hard to distinguish head from main beam, want to have them correct.

Dang it. I had hoped that the bulb swap might help.

Any chance you have pulled one turn signal bulb at a time and test to see if you can trace it to just one bulb circuit or corner of the car?
 
There's something funny because sides and heads seem to affect each other re brightness so I'm gonna take the lights off and record all the colour wires at each connection and test them back to fusebox.
Any idea on the headlight/main beam upper lower config?
Mine is lower half of light for main, upper for head.

Sorry, I replaced my headlight wiring harness with a LED setup, so I cant help.
 
Took off all lights looks to me like matchs diagram. Only thing of note back lights rely only on the two fixing screws for earth, no earth wires?
Next is to test each wire back to fuse box or dashboard, another day, beer time.

Tested all the lights wires back to fuse box/stalk for continuity and no earth all OK so next dash wiring, I've a feeling it might be something to do with stalk. At least I now now the lights are spot on.
 
Disconnected all wires to stalk ad did a continuity test.
All looks logical.
This should help me understand what's happening in each stalk position.
Gonna now connect the stalk and fusebox and diss wires to auxiliaries like wiper etc, take a live feed straight to fuses to see if I can get lights, turns as should be.

So guss what, I've sorted it.
There were two issues I found.
The black feed from ignition to column needed to be disconnected as it put feed in the wrong places.
Also the brown from front rh light, the brown from lh rear and the brown from stem were joined but not into fusebox. Two other brown leads had been crimped together with a bullet and put into the fusebox. This gave the impression the brown circuit was correct when continuity tested but it wasn't. I removed the two from the bullet crimp and fusebox and just crimped them together.
I now have all the lights and turns working as per manual.
There's been lights issues for the two years I've had the car I've had a number of goes at sorting it but always given up after a few frustrating hours. It was one of those that needed a proper looking at so thank you summersc for your encouragement as I think without it I would of given up again.
Very chuffed with myself, beer time.
