Good morning,
I write because it is presented another problem in the DAF.
When I turn on the lights, I notice that the left headlight works properly while the headlight on the left light is very weak, as if they do not come much electricity.
I checked the fuse box and everything is ok. I looked at the catalog Parst what looks like to be two fuse boxes: the big one in the engine compartment and a smaller one but do not know where it is.
I checked the earth of the negative battery and it is ok, even that of the engine.
What do you advise me to check to solve the problem?
I also noticed that when I turn on an indicator to the right or the left, with the intermittency of the arrow is also lit the light on the dashboard of the generator. Why?
Tank you
Gianmarco

Check for a good earth on the lighting circuit. The dashboard thing will be to do with earthing too. This might be handy: DAF 44 (1972) Wiring Diagram by macplaxton, on Flickr (I know it is 12V, but it is very similar to the 6V)

Good places to look for bad earths: 1. The rear number plate lights. 2. The wing side repeaters (don't think you have these though).

Actually, if I find some time, I'll scan the other diagram which show the wiring loom.

Thank you so much for your kindness.
I can not understand where are the masses of headlights. You may illustrarmele?
That of the direction indicator?
Let me explain: With the lights turned on the low beam headlight on the left is very weak and then in cruscosso you turn on the high beam indicator. If I turn on the high beam indicator turns off the beam. It works just the opposite!
I checked the switches on the dashboard. E 'is all very healthy and clean. I am sure that the problem stems from the earth. But I do not know where they are. Can you help?

This is the diagram of the loom as fitted to the car. The diagram also shows some fixing points / grommets / cable ties. DAF_44_5-14.jpg by macplaxton, on Flickr Earths are brown in colour.

Hi, i cavi di alimentazione al faro sono guasti, i fili che sono potere positivo sono ok, i fili che sono potere negativo non si connettono correttamente, questo significa che quando si accende le luci abbaglianti della potenza che vi fanno perdere tutta la potenza del tutto (quando si sono gli anabbaglianti la lampadina è negativo in tutto il fascio principale filo) pulire i fili di vite per la carrozzeria della vettura per rendere i collegamenti al negativo buono e credo che tutti i vostri problemi saranno risolti. addio Nick
(or for the english)~~Hi , the power cables to the headlight are at fault, the wires that are positive power are ok, the wires that are negative power are not connecting properly, this means when you switch the lights to high beam the power you are losing all power altogether (when you are on low beam the bulb is going negative through the main beam wire) clean up the wires where they bolt to the bodywork of the car to make the negative connections good and I think all your problems will be solved. goodbye Nick ~~ yes the wording is odd but have you ever seen how those translation sites work?

Fair play to you mate for using the translator. I'm sure Gianmarco will be able to tell us how good the Italian translation is.
Something that just occurred to me. The generator light usually pulses at tickover, if you then draw current from the battery (especially on a 6 volt car) at a stage when the dynamo is not energising, would not the symptoms described be possibly quite normal?

Good morning,
I have good news: yesterday afternoon I went to the garage to try to fix the Daf. Thanks to the wiring diagram and your advice, I checked all the masses. I found a mass (that of the defective light) really reduced badly oxidized and rusty. I cleaned well for the mass, sanding and using WD40 and Vaseline, then I replaced the rusty screws, the beacon has returned to go properly!
There remains the question of the direction indicators: When I turn the indicator on the right or left, with the engine running, the indicator light flashes of 'alternator along with that of the'' green indicator.
Thank you and good day!

Quando il motore è al minimo la dinamo non sta generando energia alla batteria e quindi la spia sul cruscotto si impulsi. E 'possibile che se il motore è al minimo e si utilizza l'indicatore si sta corrente dalla batteria a disegnare in un momento in cui la dinamo non è energizzante. Forse questo potrebbe creare il problema? Gli indicatori su una macchina da 6 volt lampeggiano lentamente. Sono tutti indicatori comportando correttamente? Sono tutte le lampadine funzionino come dovrebbero? Se è così allora io non mi preoccuperei troppo.
When the engine is at idle the dynamo is not generating energy back to the battery and so the light on the dashboard will pulse. It is possible that if the engine is at idle and you use the indicator you are drawing current from the battery at a time when the dynamo is not energising. Maybe this could create the problem? The indicators on a 6 volt car will flash slowly. Are all indicators behaving properly? Are all bulbs working as they should? If so then I would not worry too much.
