help in wiring spotties on roof rack

[Malgreen]

the 50amp Anderson plugs are for a 8mm wire from memory so probably isn’t suitable for smaller gauge wires

these are waterproof and rated for 15 amp something like this may be suitable?

thats funny, i was checking them out last night too... that would be the way to go i think Megatexture

thats a prity good price also i looked at them 6 yrs ago for connecting spotties and at repco they were like 12$ for one pair.

With the Anderson plugs you can run 3 mm wire if you like. Instead of crimping use solder and the lugs come in heaps of sizes anyway.

If you are using genesis lights and have 4 of them if there 100 watt bulbs then your drawing about 33 amps so an Anderson plug running 8 gauge wire (I think it's 8mm cross section which can handle 70 amps) down to a 70 amp relay and wire them up like a normal set of spotties. Then run your 4 spot lights to the other end of your Anderson plug.

This way you wont notice the voltage drop, your only running 2 wires and one relay and this will be more then adequate for the job.

they are hid lights and only come in 35watt and 55 watt so unless your useing after market hid kit they arnt going to be 100watt
so 50watt is 16.6 amp and 35watt is 11.6 amp

Where does it say there HIDs?

Yeah that is the maths I did when I put 4x100 on the roof. I used a big relay and 8 gauge wire to combat the voltage drop. No point turn the lights on and building in a permanent dimmer switch

Go large. Go the Anderson plug and large core wire. That's why people upgrade their factory loom for their headlights. Large core provides more power

though it did sorry mate ,must be a diffrent thread im thinking of need to go over the original post more..

Dimmer switch???? seriously?? hahah never thought about that..

i dont think these lights are hid's but they will be one day soon, looking at the 75w kit.
using 8mm cable with a 70 amp relay looks like the way to go. much easier only having one plug. but if that isnt any good i will do the 2 looms to one switch.

thanks for you in put guys. now i just need a roof rack to put them on.( thats coming soon as well )

Lol.... Yeah basically if you put big lights up and power them via an undersized circuit and wire then they will never shine to their best and they will be like having a dimmer switch. But you can't turn them up.

Voltage drop is your enemy

One loom will be fine mate. I've got 4 x 70 HIDs and a 240 watt Light bar on roof so I had to reduce the amount of wires just to neaten it up. lol

I wouldn't bother with the big ballast 75 watt HID kits either your better off with the smaller 70 watt HID kits and mounting them internally. I just finished removing my 100 HIDs (same ballast as 75s) as I was sick of them flickering and the bulbs don't seem to last either. Sometimes they vary in colour too.

The biggest drama these days is there are heaps of different ones and some are just rubbish. It's getting real hard to tell whats good and whats not.

As Mud runner said bigger is better when it comes to 12 volt wiring.
