Fog Light Relay - Where?

[Happyhenry]

I have an 07 ADV which has the factory fitted front fog lights with a switchblock mounted on the handlebar clamps. The switchblock has a spare way and I am thinking of using this to switch an LED high intensity rear 'fog light' - something like The Bede's arrangement or perhaps using the Touratech alloy LED block (£).
Does anyone know where the relay is mounted for the factory-fitted front fog lights? I have tried following the wiring but get lost under the headstock.
I am thinking of either fitting another adjacent and/or piggy-backing the power off this for the LED rear light - will this work?

It might be the one that is under the toolkit holder, under the seats.

 

[The Bede]

I fitted

... PIAA Switch by the instruments

... Power and earth from Centech AP-1 fuse panel (NN £35ish ). (Every electric bling gets earthed back to the fuse panel, including front spots, to eliminate potential ground loop interference on the Autocom and it's feeds)

...The fuse panel is backed with 3 layers of 'wonder-mat' and sits snugly, vertically, on the bungy service book holder at the back of the air box, under the riders seat. I decided to leave it bungied for ease of service access, I may change that with time

... Relay switched from Centech fuse panel. The centech is 'master' relay switched from the back of the underseat DIN socket and cuts off 1 min after the ignition. (Posh 60amp relay from AES)

... Fog light relay (20amp)sits under seat in the space under the 'tool-tray.' I ditched the tool-tray completely and dropped both the 'master' relay and the fog-light relay in there. Few inches of Maplins sticky back velcro to hold the gubbins in place.

... Off-cuts of any old wire really

... Piece of un-made circuit board material, cut, drilled and chamfered to leave a small mounting lip just below, bottom-dead-centre, the licence plate.

... Nippy Normans flexible LED tail/brake light strip £20ish

... Cables run up the licence plate hanger under the 'load-deck' cover to the relay. Short cable extension needed.

... Add a sprinkling of self-amalgamating tape, lead free solder, crimps and PVC heat-shrink sleeving.

... Spray with ACF-50 to taste ... bon apetite

John, I'm almost certain that one is the starter relay (http://www.r1200gs.info/R1200GS-WD2.pdf), though I stand to be corrected. It would be very handy if it was the fogs!

Thanks Bede. You showed me your set-up in Wales. I was trying not to start from scratch but simply to piggy-back off the existing front set, since the LEDs draw very little power, to do which I've got to find the factory-fitted relay.

You're right when I've had a look at the 1200 drawing I've got saved, sorry

I have been looking at a rear fog setup as the foggy season approaches again - in your opinion is the NN man enough for the job ? Could these be run as Aux rear lights wired in to the fuse setup permanently (i.e Always on?)

Thanks

... This is how it looks in fog mode, 21W equivalent. Not blinding, but I figure more light and extra is better than less when it'e getting foggy and misty. I specifically didn't want anything either massive, pannier, or top box mounted.

... If you want a 'slave' tail/brake unit you can wire the NN LED strip accordingly, it has a 3 wire connection, yellow=5Wtail, red=21Wbrake, black=common.

... Tap the existing rear brake light feed for tail and brake relay trigger voltages, probably at the tail light unit.

... Robert's your father's brother.

That's a particularly cunning anti speed camera device you have there.

A small thing, but it's illegal to have a combined rear brake/fog light

http://www.opsi.gov.uk/si/si1989/Uksi_19891796_en_16.htm#nsch11

Section 10.

You don't want them to have another reason to pull you, or do you?

Not sure that is what the Reverend has ... this is a stop tail light unit that he choses to operate as a fog unit, not the other way around

The Bede .... Thanks for the photos, very appreciated, having seen them , I feel that maybe it is more appropriate to get the NN unit wired in as intended ( Brake / Rear light ) Do you happen to know that If I piggy back this off the existing brake/rear light wires, would this send the Canbus into overload confusion?

Thanks

... Exactamundo, my brake light/tail light is bog-stock and independent of the switched LED fog strip.

[/QUOTE]

... For a 'slave' brake/tail light, all you're tapping off the tail lamp feeds is enough current to energise the switching relay coils (pin 86 & pin 85) and any micro-LED in any switch you use.
... +/- SqRtSweetFA, too small a current change to trigger the canbus.

... Higher current LED 'lighting power' is from the battery/fuse-panel and is switched via pins 30 and 87

I still don't know where the fog light relay is - any clues anyone??

 

[Daffy]

I would guess that it doesn't have one as the feeds for the lights are controlled by the control unit i.e. no fuses and no relays.

unless someone knows better?

Fog lights are AFAIK the only conventionally fused system on the GSA.

The fuses are hidden under the right side fairing cover (the one over the fuel tank), perhaps the relay is there as well?

 

[Happyhenry]

Cheers kKop. I'll take a shufty under the cover and see what I can find.
