Hey FiatForum

My Punto started having an issue with the headlights.
When I turn ON the dipped beams, the on on the drivers side (Left side for Portugal) lights up too dimly. And right side one lights up normal.
If I switch ON the main beam I can see the dipped beam becoming brighter. And at this point if I switch off the main beam, the dipped beam will continue to produce normal brightness until I switch them off.

I am thinking a earth problem, maybe?
But then again why would it get brighter, and stay brighter after using the main beam.


Also can you help me identify the earth locations in Punto, the Heynes manual lists a lot of "inner wing" earth locations, I am not sure where those would be.

For the left hand driven Punto, I know the interior has two earth locations: one at the luggage compartment, on the left side, and another one on the passenger's footwell.
But I don't know were to find the earth points in the exterior of the car. Haynes lists like 5 different ones.

I think the headlight Earth is in front of and lower than the battery. There is a box there with about 9 wires. I think that is E3. E4? for the ABS is under the ABS unit on the wing. I think the 5th Earth location is the battery post? Power steering earth comes from the battery.
