Main beam not working update

[bobhenry999]

Ok,

Sorry for the delay.

I have today managed to have a look at the the lack of main beam on my 815 at last.

When I depress the switch on the column stalk there is an audible click from the relay.

I checked the bulbs and they were okay. I took the cover off the relay and operated the switch, and the "Nodding Donkey" bit did it`s job and clicked down on one of the 4 lobes on the shaft and turned it to rotate the rectangular bit through 90 degrees to either be vertical (No contact) or horizontal (Made contact), but still no main beam.

I have cleaned up all of the contact points but am now at a loss as to what is the problem.

Any help would be appreciated.

If a relay involved, have a close look at the solders, a dry joint may be the cause, if needs be just re-solder them all and see if that helps

All the joints and connections look okay, and at the last MOT it was all working well.
Can`t fathom out why it should suddenly stop working, especially as the relay appears to be doing its "Nodding Donkey" thing, and all bulbs are ok.

Unfortunately (Or not) I am off to France on Monday for a week, so please don`t be put out if I don`t reply to any messages of help as I don`t take my lap top when I am away to help, as I don`t take my laptop with me on holiday to prevent me looking at work e-mails !

Any help would be welcome though.

Chaps,

Okay, back from holiday and I still can`t get the bloody main beam to work.

I think I have 2 choices that you may be able to help with;

1. Does anyone have a spare relay that I could buy or even borrow to confirm that the problems lies in the relay or not.

2. As I NEVER use my car at night, does anyone know how I could rig up a switch to operate the main beam for the MOT test, as that`s the only time it`s ever used, along with the wipers and washers. In fact, the washer bottle contains Italian water from when I bought the car in Turin 5 years ago !

Your thoughts/help would be appreciated.

Are there 12volts at the relay 'in' side and 'out' side?

[bobhenry999]

Richard,

Sorry to be a numpty, but electrics are not my thing.

How do I check that, as there seems to be quite a number of wires going in to the relay.

Its a hard slog going through the wiring diagram but worth it as you understand a lot more about your car afterwards:-)

A simple £5 multi meter is all you need to trace circuits. Everyone is in the same boat unfortunately.

[Richard Fridd]

Identify the wire which goes from the relay to the headlamp, then test for voltage between that terminal and an earthing point (ie battery negative post or bare chassis metal) Either with a test meter or 12V bulb. Which terminal? Diagram required or perhaps local garage help required if not familiar with electrical systems.

Okay chaps,

I will have a go at your suggestions at the weekend and update you all afterwards.

I can print you an A3 wiring diagram for your coupe if you want.....

Tim,

That would be a great help, as I am using the A4 one in my Repair Shop Manual and my old eyes just can`t fathom it out.
