My 110 3.5 1987 have always started without any problems.

All of a sudden it startet acting like this:

1. When i turn the key to start, the battery light are on, nothing unusual in this

2. When I turn the next step key to start, nothings happens but the fog light and driving light flashes in the panel (se picture)

3. I have unplugged the light and fog light contact now, and the engine will start, but the light and fog light still flashes in the panel.

4. 3. I have changed the Light contact to a new, and now the car can only start if the light is off, and the foglight are still flashing in the panel.



What to do??? any help are appreciated.

 

Sounds like you have a shortcut somewhere in the lights circle.
Have you checked all of the lights to verify that no contacts were melted, no wires are exposed?
(if you need the electrical diagram, you can download it here)

I checked the wiring and al seems okay.
I also tried taken out the fuses for the foglight, but the warning light for the foglight still lights up.
If I switch on / Turns off the light several times, the fog light warning light goes out and I can start the car.



Fog light warning come up, car can't start

When I turn the light on the fog light waning comes up as well, the car can't start

2-5 sec later I can start the car as normal.
