getting there (confused that is)
right continuing saga of my headlights not working. First connected the headlight outputs from the relays direct to the battery and the dipped and
full beam work so the problem is nearer the column.
Got a multi meter last night and started checking. I have switched 12V at pins 86 & 87 which I assume is right.
Problem is withe the iginition on I have 12V at pin 85 which oes to the column switch whether it is on or not.
But wouldn't that mean the lights are on all the time rather than not at all?
So two problems, first why is pin 85 live when the column switches for dipped and full are off? and secondly why aren't my lights on all the
time.
Lookling at the column problem first. I have wired the brown/white & brown/yellow from left of the column and I'm starting to think it
should be from the right where the dipped switch is. I have more than one set of brown/whte & yellow wires, how do identify pins. I can't
see any markings on the bit that unplugs?
secondly why isn't why relay switching? I'm starting to think that I don't understand how the relay connects internally and have
wired up the connectors wrong.
Any assistance as to how to proceed next most apprecited.
Sorry for the long post
Nigel

more post scouring and I'm starting to doubt the relay wiring but must admit to getting really confused with the technical descriptions which
other people seem to understand
Can anyone in laymans terms please confirm the following is correct for connecting the relay.
87 & 86 have 12v switched supply through a fuse
85 is connected to the column switches
30 is going to the lights
If not how is it connected as that is what is shown on the diagram. Problem is I'm getting more confused the more posts I read
Thanks, really want to get this sorted and put this whole wiring misery behind me.

Your connections appear to be correct [85 &86 on both relays are conected via a fuse to the white wire from the 3 - pin connector in the VG
loom]
I found that my sidelights came on without ignition but I needed to switch to ign 2 to get the dip/main/flash to work [although strangely when i turn
the ign off, they continue to work (?) ]
Just to be clear - 85 on the dip beam relay goes to 56b on the switch ; 85 on the main beam relay goes to 56a on the switch

Remember that the Sierra Switches fire the relay, and the relay fires the Light bulbs.
Now depending on which switches you have, depends on whether the switch puts Live or Earth onto the relay.
Which ever one you have, you need the opposite at the other side of the coil.
So if the switch puts out +12v, then the other side of the relay neds to be earthed,
If the switch puts out an earth then the other side of the relay needs to have +12V on it. Otherwise the relays will not fire, and the lights not
work.
Bear in mind, that the Light switch then feeds into the Dipswitch, which switches between the two relays for Dip and main.
Then, remember that the Flash Switch will need to be putting out the same condition as the Headlight switch, as this will operate the high beam when
you operate the flash (headlamp flash) switch.
It all needs to be correct to work. Or you will get funny faults like the lights work and the headlamp flash doesnt (or vice versa).
SO its like this:-
+12v - Headlamp Switch - Dipswitch - Relay - Earth. (or start this run with Earth and end with +12v if you have the other wiring / switches)
Personally I would check whay condition you get from the Flash switch first, and then put the +12v or earth on the relay to suit that. Then put the
same condition on the headlamp switch (+12v or earth).
Then it should all work.
The problem with wiring is that you cant see the electricity, its like water, but you cant see it!.
Think it through and work on it bit by bit, treat it as a single circuit or part of a circuit. DONT look at all those wires and slap your forehead in
dispair. Just look at the cuircuit you are dealing with.
Then when you have it all figured out and working. - WRITE IT DOWN, as you may ned to sort it again, and good records will help.
Have fun..

Just been reading through the earlier thread - pin 15 on the switch needs to connected to earth and 56 needs to be connected to pin 56 on the stalk on
the the other side of the steering column.

Umm
On relays connections are 86 and 85 are the internal electromagnet that operates the relay so to work you have to have one to +12V feed and the other
to ground via your dip / full switch 56A or B.
So connecting 85 and 86 to the same feed (white wire) will do zilch.
87 on the relay is normally the +12V feed to be switched and 30 on the relay should go to the appropriate lamps.
So (LH column switch - dip, main, flash )
30 to the lights
87 to the 12V switched suppy
86 to the 12V switched supply
85 to 56A or 56B from the column switch
15 on the column switch to earth.
56 to 56 on RH column switch (lights off / side / head
Main 56A is Brown / yellow
Dip 56B is Brown /white
56 is Brown black
15 is Brown
RH column switch:
31 (Brown ) on RH column switch to earth
Other wires are for the indicator switching (don't lets get into that yet : )
PS Please make sure you have a temporary 15A fuse in the +ve battery connection at the battery just to avoid disasters

thanks for the info fellas, much appreciated. So last question for today before trying things out tonight.
It looks as if my column switches earth when switched seeing I have 12v when the switch is off so I suspect a bad earth at the column.
So if I earth either of the leads from the relay going to the column before it reaches the column the relevent dipped/full lights should work. That
then tells me the problems lies with the column wiring?
Is that correct, a yes or no will do
Thanks again it's much appreciated.

Yes 
When column is in use your earth should be through 56-56-31 - earth

Yes????
Probably
If it looks wrong it probably is wrong.

I'm getting there and think I may of found a problem. The brown/black from the dipped/full beam switch (pin56) goes to the other side (light
switch) there is two brown/blacks though, the one that goes to the other pin 56 and the other is at the moment not connected!
Where should that go to as my wiring diagram only mentions the brown/white and brown/yellow(56A & 56B) on the other side.
Could this be my problem? if so what does it connect to, earth?
Many thanks
Nigel

I think if you connect the second one to earth your lights will be on all the time. Try leaving it not connected and make sure your 31 IS connected to
earth

You are quite correct. that should have read 86 & 87 connected to the white wire.
(I didn't have my diagram with me tis morning)
