Hella Rallye 4000's Wiring

Spot beam is usually mounted on the drivers side. Were dose this yellow wire
go to in the light that should tell you what it is for, and yes 25 amp
should be fine as I= w/v so 200 watts divided by 12 volts = 16.6 amps, I run
a 20 amp fuse on my 2000 series no problems.

Greetings to all
I have almost completed the installation of a set of Hella 4000's on my 2000
Triton ute (excellent early Xmas present from wife :) ) . Using a Pirahna
wiring loom. All working ok - but what on earth is the yellow wire out the
back of each light to be connected to? The brown wire is positive and blue
is earth. Yellow...???? The lights are working, but the yellow wire must be
for something. Hella wiring diagram doesn't help.
Is a 25 Amp fuse sufficient
I have one pencil and one spread - should the spread beam be on the
passengers side to light the edge of the road - or doesn't it really matter.
Thanks for any help .

Steve,

I think the yellow wire is for Daytime Running Lights in addition to having
them on when the high beam is on; god knows why you'd want a pair of wacking
big spotties on when in the daytime, even if it is snowing.

My Rallye 4000's I have installed on my UD truck. I have chopped the yellow
wire at the back of the plug, and just used the other 2 wires. I know I
investigated this wire at the time, and whatever we found out, we elected to
chop it. Works damn fine these past 2 years.

Cheers,

Rod.......Out Back

Thanks to both Roc and Rod,

I have done some further investigations and the yellow wire is only in the
harness - only the blue and brown (or equivalents) come out the back of each
light. So seem to have no real use - will just ignore (probably do the cut
like Rod!!)

I took the right guess and the spot is on the drivers side and spread on
passengers. Should be able to test out tonight once I get the fuse in - have
gone for a 30amp but also have some 25's if 30 too much - wouldn't have
thought so but can never have too many spares.

Thanks once again people

Cheers

Steve

problem with having too higher rated fuse is that wires can get to
melting point before the fuse blows, which defeats the purpose of having
a fuse
us a 20A fuse first, if that keeps blowing then go up to a 25A
not the other way around

Kev is correct the fuse is there to protect the wiring, as I said before I
(amps)= w (watts)/v (volts) so 200 watts divided by 12 volts = 16.6 amps.
Fuses are a slow blowing device unlike circuit breakers a 20 amp fuse will
take a inrush current well above its 20 amp rating. Fuses only blow quickly
when there is a short and a short causes very high current, here ends the
lesson.
So it doesn't matter what lights you have if the globes are 100 watt each
you will have about 16.5 amps so a 20 amp fuse is fine.

And with luck you will have way more than 12 volts there when your cars
running (around 18.5-14.3 good) so redo ya sums and walla, lower current
again.

Not only that, ya typical el-cheapo K-mart bulbs are usually well and
truly over rated anyway, ie, 100w H3 bulb only drawing anywhere from 6

Yes.....but....

Arent you really looking to calulate for worst case current requirements?
What if you're running hella bulbs (chrissy pressie??) AND, you have to run
the lights for a time with the engine off? You really want to assume that
as a minimum the wires will be running the higher wattage bulbs and lower
voltage(hence heaviest current).

Thats the way I'd do it; I'd rather have too heavy cable than too bloody
light...

I dont want luck to be a part of it...

True, but even at standstill (no charge) your battery should have around the
12.8 volts if its any good.
