Outer Limits 4x4 Board

Hey all,

Wired a set of spotties into Project Gutless last weekend. Wired in properly, with a relay to the high-beam and a switch on the dash. Got a weird thing happening in that when my headlights are turned off, the relay switches on and the spotties come on!

They don't come on when I'm not using high-beam, that part is alright, but when I turn the headlights off at the stalk thats when the spotties power on again.

I've checked and as far as I can see everything is wired according to the diagram.

Am I correct to have tapped the relay from where the high beam wire goes into the back of the headlight? Or where else can I draw it from?

Long story, but to solve problem simply - rewire the relay ACROSS the headlight bulb. I bet you are tapping 12v and groudning the other terminal. Change it so that the relay coil wires are across the high beam wires - doesn't matter which way round.

Hi 4130warrior, as me3 posted.

It’s easy to do, you will have H4 globes and these have a three pin plug on them.

The plug has a wire on either side and one at the top. One of the side wires is your common and the other side is your high beam.

Simply run one wire from each of the relay’s coil terminals, that’s terminals 85 and 86, to the two side wires on the headlight plug.

Just add your switch to one of the wires.

Cheers.

thanks guys you're absolute champions as soon as I shake this bloody flu I've go have another crack at it.

If it's any consolation, you're not the first person to do this. Of course, if you'd SEARCHED properly, you'd know that...

Why search when you can be a n00b and ask dumb questions

On the rear of the driver's side 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?

I think this should go into the bible as i spent countless times searching for this information before i ended up giving up and just having mine on a switch.
The wires stumped me when it did the same thing as this bloke and couldnt understand why this is good info
Just my 2c
