Ahhh! Bloody Electrics...

[Dan]

My SVA test is a week today and I am already suffering from sleep deprivation and stress levels are rising so high I can hear blood vessels popping. But enough of the symptoms and on to the cause...

I have a number of things that have gone unoticed until now. The main item being the headlamps. I'm using halogen lights so have fitted a 25A Fuse instead of the standard 20A. When I turn on the lamps the side lights and rear red ones come on, but no dipped headlamp. If I switch to full beam I also don't get anything - BUT If I toggle the main beam by pulling back on the switch gear I can hear the relay click and full beam comes on. Why oh Why doesn't it work.. Does it use a different relay of the same. Could the connections on the back of the stalk I'm using. I swapped the ones from the donor which were angular with rounded ones from a later model which has an additional 2 connectors... Any pointers.

I had the same problem and after a few days of pulling my hair out called out an auto electrician to come and look it over for me.

He explained that within the fuse box some of the fuse terminals are connected with little metal strips and that these can brake quite easily if the fuse box is roughly treated. He then proceeded to solder extra wires between right and left headlights at the fuse box end and they work fine now. Not that helpful I know but could be worth looking into.

Cheers,
Andy

Danny,
On the donor, the "pull to flash" main beam switch works off a different supply to the "centre" (dip) and "push back" main beam switch.
Before you tear any more hair out, have you tried operating the lights with the ignition in position 2 (engine run)?

I don't know the Pilgrim loom, but I'd guess it was wired the same way.
How many wires do you have on the Pilgrim loom to connect to the main/dip stalk?

Simon.

Thanks guys for input, Problem not yet solved but am now closer to the truth...

Checked fuse boxes first and power is being supplied to and from...

On to the light switch (the R/H 3 position stalk) and again all appeared to be in order with power being supplied and sent on...

The power for the lights comes in on a blue wire to the L/H stalk. With the stalk central the power is routed out on a red/green wire and when pushed forward a Blue/white one.. Indeed the pull to flash main beam is supplied from a constant feed (a red wire) which routes it out on another...

The bottom line of my investigation so far reveals that the switch gear isn't to blame but more than likely a dodgey connection on one of the relays from the switch gear. I just wish I found this problem before installing the relays in the bottom of the footwell

Another symptom discovered is the fog lamp not functioning, This is fed from a connection on the relay (prior to relay). which could indicate a break in the wire between the last switch gear and relay...

Moral of story, Trust no one especially a pilgrim supplied wiring loom {-}

Hope to get it sorted this evening..

Dan.

Dan,

You may want to swap you light relays around to eliminate that problem. If you main beam comes on when you pull the stalk, the relay being used for that circuit is OK. Swap over and try again. This will tell you if the other relay is working.

FYI, you will need you ignition switched to posn. 2 to get the dipped beam on. You get nothing without it.

As for the fog light, the wiring diagram shows that the fog light is simply fed from a feed off the main loom and not the lighting relays. These relays are only used for the front headlamps. The only thing I needed to do for my fog light was to run a separate earth. It all worked fine after that.

Just make sure that the fog lamp tell tale lamp is also illuminated when switched on. See below for a wiring diagram.

Good luck,

Have checked the diagram again, and you have correctly pointed out that the power for the fog lamp comes from the back of the 'DIP SWITCH' Which I guess is the switch on the left side of the wheel.

The numbered wires below are for (I Believe):

1) Live in from fuse box
2) Feed out when lights dipped
3) Feed out when lights on full beam
4) Feed out when switch gear pulled for full beam toggle
5) Power for above

Am I correct in these assumptions?

I had the same problem!! Are you using the new Pilgrim Loom??? If so then one of the Relays is wired up wrong.

Can't remember which one but your symptons sound the same. I only found out by blowing a couple of fuses in my investigations. :} :} :}

Check both the relays. I ended up asking Pilgrim for the terminal numbers on the Relays to get it sorted.

Although it is Pilgrims mistake they were very helpful in getting it sorted.

Thanks Frosty, I will be taking this up with them first thing tommorrow.

Da,

I would also change the fuse back to a 20A fuse if that is what is recomended. If you're using a higher than requested fuse, you could be inviting trouble as if the circuits fail, they will take longer to fail and may cause more damage than you wish (eg. fire).

Just a thought.

Would it be possible for one of you to post the correct wiring?
