I need some help on wiring up my spotties please .
I got some narva driving lights and put them on the roof. So far I think I've got everything right from the little diagram they give, the only places I can think it might be wrong are...
-I haven't connected the switch to high beam active, I've run one wire from the relay to the swith then another wire from the switch to earth. Is that ok? Also does the switch need to be plugged in a certain way?
-The earth from the lights and from the relay are on a bolt that's: just behind the battery, holding a plate to the firewall and may not be conducting enough.
-Does the wire from the relay plug into the back of the light bulb and the earth sort of comes off the side?
-Would connecting relay to the negative battery terminal rather than the positve have blown the relay?
Thanks for any help, it's such a fussy job and it's getting really annoying, been at it for hours, and driving round to get extra bits.

ahhh the infamous suzuki spotlight wiring i know royce had a diaqram of it somewhere

it is a bit different from most cars due to the way suzuki make their high beams work

[11_evl]

terminals on relay...
30 connect to...battery
87 connect to...lights/ fan / ect
85 connect to...earth
86 connect to...switched 12v

you can also have constant 12v to 86 and have the 85 switched to earth if that works best for you

WIRING AUX. SPOTLIGHTS

One of the questions I get asked most often is how to wire auxiliary spotlights so that they come on with main beam.

The Vitara's wiring is awkward to do this with, as a relay is normally triggered by the "trigger" terminal getting a positive feed to it, this actuates the relay and passes the switched live through to your spotlights... well, that's the idea with "normal" vehicles!!! The Vitara's headlight wires are positive most of the time! So we need to wire the relay up in a different way - we wire the relay so that it always has a positive feed to the trigger terminal, and we wire the earth terminal to the headlight cable that is normally positive but which drops to negative when highbeam is on. Hmmm? get that? it's a little awkward isn't it? Anyway... here's how to do it:



On the rear of the offside (driver's side in the UK) headlight locate the red wire with silver bands around it, if you have a 12V electrical tester check that this wire is positive when the headlights are on and it then peculiarly goes to negative when highbeam is on. Clip a Scotchblock onto this wire with a piece of wire in it long enough to reach back to where you are going to locate the relay, and attach this wire to terminal number 85. This will be the "trigger" for the relay, the relay will always have a positive feed to the normal trigger, and live going to the "switch" of the relay for the auxiliary spots, so the relay will click closed only when the earth terminal gets a negative feed (as it will normally be positive... "d'oh! my head hurts Marge!").

Take a wire off the battery's live terminal and with an inline fuse holder connect it to terminals 86 and 87, these are the normal trigger and the input terminal of the relays switch.

Connect a wire from terminal 30 - the switched output of the relay - and connect this to the positive wire of your spotlights, the spotlights should also be earthed to either the vehicles body or chassis, or an existing earth point (probably the best idea I've found).

Hmm, and that's it... when you put your headlights on the wire coming from the Scothchblock attached to the red wire with silver bands will be positive, so the relay will not click closed. However when you "flash" your headlights or switch to mainbeam, that red wire with the silver bands will drop from positive to negative, then, as the relay now has an earth it will click closed and switch the positive feed to the spotlights on... and your spots will come on so you can flash other roadusers, or when you're offroad in the dark, etc...

Ok?

U a sparky Bruce ?
that was a detailed explanation ! Zooks headlights soon sort out your training when you muck about with the circuits !
"what tha"

[Bruce]

No mate (sometimes I wish I was) I kept this from when I did my lights on the GV and thought it would come in handy later. Hope this helps

[Mitchy]

Right.
Well firstly does anyone know how to do it without wiring it up the the highbeam? They're mainly for seeing over long grass and scrub so I don't really need normal highbeam on too. Anyone know anything of the things I said above?
I think I got that diagram by Royce from the NBS forum somewhere so I'll check it out. And I think I've read what Bruce posted on outerlimits or something before but it was too complicated at the time. I've read it about 10 times now and it sort of makes sense. It's basically the normal thing reversed isn't it?
I'm really looking forward to more hours of tinkering around!
Thanks heaps.

i cant be stuffed reading the whole lot. but if i ever put some in i would just wire them into my park lights.

Remember that the function of a relay is to use a low current switching circuit to turn on another high current switch in the relay that is usually straight from the battery to the load (in this case the spotties).

Legally, spotties must only be on when you are on high beam. It is really easy to bypass the high beam circuit, Just run a wire to a constant on power source instead of from the high beam circuit (ie. the low current side). But it is illegal!

I highly reccommend taking your time, doing it right becasue in my experience on dirt roads if you take short cuts with the wiring, you get loose joints and faults all the time that drive you nuts when you really need them. Woops! I did not see that kangaroo that just took out my radiator becasue my spotties were not working...

Bruce thanks for the detailed explanation of the intracies of the Suzuki wiring. I will probably put spottties on Rod's Rig one day, but not many roos down here in Brissy.

I think this is Royce's wiring diagram that I found on NBSclub forum

Hey Micth have You worked out your wiring yet? Ill try and explain a simplified way to do it.

Roycies diagram is probabily confusing you as it has a few relay etc. He has done this because the zuk doesnt switch headlights by relays just by a switch, well the sierras do anys. What you want is just to connect up a simple set of spot lights.

Ok we will use the highbeam trigger on this to keep it legal. Suzuki head lights are ground switching. This means all the terminals at the back of the headlights will be at 12V when they are off. For instance when the high beams are turned on the GREEN wire from royces diagram of the headlight plug goes to ground.

So to wire up your spotties:

1. split the right wire going to your headlight ( looking at the back of the plug, just use the drivers side headlight if easiest).

2. From this junction take a wire to '86' of the relay.

3. Directly opposite '86' is is '85', connect this to 1 termainal of a switch.

4. Take a wire from the other terminal of the switch to '30' of relay

5. Also from '30' connect this to a 40amp fuse then to 12V, the positive terminal of the battery.

6. Now connect '87' to the positive wire of your spotlights.

7. Connect the other wire of the spotties to ground, or chassie.

So the spotlights should turn on when the highbeams are on and the switch is turned on.

Cheers Dan

Hey Dan thanks for that, I went over to see your dad yesterday and he fixed it up so they come on by themselves. He said that your's was a pain in the arse to do. Now it is...
30 and 85 to positive battery terminal
87 to lights
86 to switch, then switch to earth
so now I have power and earth for both circuits

[Zook_Fan]

So can someone elaborate on this again please we are totally lost

[royce]

there aint much more to explain, what are you struggling with

[shep]

and then if we ever meet at night you will cop 2x55w hid high beam
and two of lightforces finest hid driving lights burned into your eyes.
driving lights trigger of highbeam peoples.

[Zook_Fan]

we are somehow bypassing the switch and that means that it doesnt need the highbeam to be on to allow the lights to be on. We have tried about three different ideas from this page and we still do not have it right

[royce]

you are earthing the relay to the body, dont earth the relay follow the diagram

draw exactly how you have it wired and post up

[Zook_Fan]

[Zook_Fan]

baffle me please!!

[royce]

thats wrong read the diagram

[Zook_Fan]

ok its all good now followed what you said on this: http://nbs4x4club.com/forum/index.php?topic=4238.0

[shakes]

I found this picture on I think Marts thread. And because I'm a numpty when it comes to wiring I'm making sure I've wired this right before I run power through it. Abuse away

[Scrawny]

Ignore that diagram and use the one further up.

Thats how i did mine 2 weeks ago, sweet as, its all a lil bit confusing isnt it when you dont know that suzuki's switch the earth rather than the +12v side.

As soon as i found that there was +12v at all headlight terminals, i did a quick interweb search and i had my answer.

Follow the steps above, can't go wrong.

I would but I already have the dual relays and the existing loom has been butchered. So trying to clarify if I've switched the spots right or not?

[sickzuk1]

Ok.. I have had a look through all the diagrams etc..
But all I want is two have the spotlights hooked up directly to a switch.
So the only thing that will turn them on is if I flick the switch..

[JrZook]

Use this and instead of going from the switch to teh headlight wires connect to ground.

[sickzuk1]

Ok sweet.. Wait.. So no fuse at all?
Oh and also.. What does the relay actually do?

[Zook_Fan]

fuse should be put in the line as close to the battery as possible then run to 86 and 87. the relay is just a switch, it recognises when you are on high beam and turns the spotlights on.

edit: didn't read your previous post. if it were me i would run a lead straight from power, through a fuse, to a switch and then to the spotlights. but i don't really understand the need for relays in autoelectrics so this would probably lead to huge voltage drop or something like that.

[sickzuk1]

Ok.. But if there is no high beam involved in this set up.. Than is it actually needed?
