Ok, firstly, I need to apologise, as Im young, not very good at electrics and some of the methods here may seem a little unusual!

I have bought these spotlights with this wiring kit, to put on my bull bar.

I put them on, and wired them up as below. I didn't know where to wire into the main beam for the relay, so I found the correct wire running down the drivers side wing and cut away some of the insulation so i could wrap the wire to the relay around it, then taped it all up again.

However, to start with they both worked, but not very bright. Is this because of a bad earth, not heavy duty enough wire (it should be ok as it is the wire from the supplied wiring kit!), or because they are wired in series and need to be in parallel?

Anyway the next day, I noticed that the first spot was working very brightly, and the second not at all. After a bit of fiddling I realised it was earthing through the case of spot 1.

So do I need to wire them in parallel? If so, how? There were only 4 connections on the back of the relay, only 1 of which goes to the spot... so how do I connect the second spot up?


Ive also just ordered a lightbar with 4 lights to go on the roof, which I was planning on wiring up in the same way but with an override switch for on road use. But il wait til Ive got this problem sorted before I start on that!

Cheers
 
you need to put the live ends of both spots together and back to the relay, then both earths from the spots seperate.

cheers for the links trewy. Just reading all about relays now!

On the second link, what is the bit called between the relay and the spotlights? looks like it splits one electrical wire into two, one to each spot. That is what I need!
 
The problem is griff, the relay has ONE spade connection on the back to go to the spots, so how do I split this one wire into two? One end of the wire goes to the relay, the other to the little bullet connector on the first spot positive wire. At neither end can I see how to attach another wire to go to the second spot thus wiring them in parallel!

Scotch block?

Scotchblocks - ****blocks - either fit both wires into one push tag or use a piggy pack tag.
 
You have it wired up so that the earth of spot one goes to the positive of spot 2.

Earth both spots to the mounting bolts that they are attached with.

split the positive into 2 wires at spot 1 and take the second wire to the positive of spot 2.
 
If yer dunt know............................is it wise doing yer own wiring? :eek:

yeh im not thick or anything, christ I managed to retrofit a tdi engine pretty much by myself! Just havnt done a great deal of wiring before, and dont know all the names and such!
 
you can use a piggyback spade connector on the back of one lamp to loop across to the other one or from the relay output to connect 2 wires.

thats fantastic guys, thats pretty much all I needed to know!

So I need to make a trip down to halfrauds, get me a pack of piggyback pushtags (although I guess Il only need the one!), then wait for a sunny day to fix it all up!

Cheers also for the tip to earth onto the mounting bolts ratty, I wouldnt have thought of that!

there's nothing wrong with scotchblocks (insulation displacement connectors), provided they are used correctly.
i.e. with the correct size of wire, crimped correctly and in applications not subject to extremes of temperature, humidity, water or dirt.

the whole telecommunications network runs on em after all!
