Still not convinced mate ? When I get the exy back, I will run some more exhaustive tests. But I believe these results speak for themselves. emoticon

Re: Heavy Duty Wiring Loom


Brett,

It is not that I am "not convinced" but I like to see facts of whatever upgrade is being proposed and it will be of interest and benefit to many other readers.

You don't need the higher wattage bulbs to perform this test, you have already done half of it, so when time permits, just do the test as I asked and as suggested in one of the links you provided to get accurate results.

The results may speak for themselves as you have stated, but they will speak for themselves even more when you do the test the correct way emoticon

Re: Heavy Duty Wiring Loom


 I will do the complete test tomorrow as asked.

 But, these wiring looms are not some 'hiclone' fantasy product. The theory and practical sense prove they work. And the fact that aftermarket spotlights are wired with thick 10 gauge cable and not spagetti wire supports this.

 Why not compare the thickness of the wires at the rear of your headlights, to your spotties. emoticon

 I shall make a believer out of you. emoticon

Re: Heavy Duty Wiring Loom


Brett,
As an electrical engineer, can I add some confusion into the discussion ?
Are the globes rated 12V, 13.8V or other ?
Reason I ask is that while under driving the globes with less voltage will reduce brightness (and increase lifetime), so will OVER driving the globes with a higher voltage INCREASE the brightness and DECREASE the lifetime.

Re: Heavy Duty Wiring Loom


Well I think that test proves enough... doesn't have to be both sides. It's a parallel circuit... and the extra distance between the two is minimal, certainly not enough to make a big difference.

At the end of the day I would find more comfort in having installed a thicker wired loom having upgraded my standard bulbs. Reason being that the factory wiring has been sized (albeit minimally) to the supplied headlights... if you put in a brighter globe for safety purposes as Brett has mentioned... then it is good practice to upgrade the loom.

The voltage drop seen in the test is quite high...8-9%. So you would expect a diminished output with the factory wiring.

Yes Nathan it is a parallel circuit, but Jalal is right, we should either test both sides or atleast test the longest wiring loom.
With the increased length of the driver's headlamp wiring, there will be more resistance, so with the same initial volts and the same globe resistance, then there will be slightly less amperage and a lower voltage across the globe filament (in theory).

 I am also qualified mate and I still do some 'secondary exployment' from time to time for extra cash. I have fitted numerous upgraded wiring looms to vehicles from old 60 series Cruisers to brand new Holden Monaros. Because of the amount of night driving we do at work, each vehicle has an upgraded loom to cope with this issue. We rarely blow globes and have never had any wiring melt. We use massive 130/100 globes in some of the 4wd's, as well as decent spotties. I have tried to convince the boss to get some FATBOYS, but he wont be in it.

 Once you move into the 100w area with globes, the standard wiring can't cope for long periods. They may be fine for a quick 30 minutes trip, but what about several hours or night driving on high beam. This is when they melt, short out and sometimes, cause an expensive fire.

 Re the rating, it depends what part of the world you are in. All headlights I have seen have manufactured in America or Australia, the rating of 12v written on them. Some England brands do have 13.2v on them.

 However, when listing lumens and output, some companies will conduct this test with 13.2v passing through the globes. Therefore giving higher readings. Most reputable brands carry out these tests using 12v for continuity.

 I understand what you are saying regarding over or under driving the globes, but whether you run stock standard spagetti wires or a heavy duty loom, the globes will be getting over 12v anyway. Technology these days should allow these globes to be run with higher voltage/current, but I agree, their life may be shortened.

 Ask anyone how much voltage a car battery contains and 99% of people will reply "12 volts". As you are aware, start the car and you will have more then 14 volts there.

 Headlight globes are designed to work on a miminum of 12v. This is what the manufacturers specs are for the optimum longevity vs performance scale.

 Sorry to be long winded on this subject, but we are here to educate others and allow others to have some information before trying a new product.

Just like the:

 Hiclone - failed.
 Fuelsaver - failed.
 Grounding kit - undecided.
 HT Exhaust system - passed.
 TBS - passed.
 Iridiums - passed.
 K&N filter - passed.

 I will prove the heavy duty loom works with higher wattage globes in the xtrails system. Whether you have the need to install one is then up to you. Stay tuned.

Re: Heavy Duty Wiring Loom


RESULTS : TEST #1

BATTERY: 14.14v
 Globe voltages are measured across the actual pins, not at the battery.

Standard 55/60.......Factory....LOOM
Passenger side lo.....12.78.....13.88
Passenger side hi.....12.72.....13.84

Driver side lo.............13.01.....13.83
Driver side hi.............12.94.....13.77


Hella 55/100............Factory....LOOM
Passenger side lo.....12.84......13.83
Passenger side hi.....12.34......13.68

Driver side lo............13.04......13.85
Driver side hi............12.61......13.74


 Suprisingly, there is a higher voltage drop of the factory wiring to the passenger side. But with the LOOM installed, this is almost negligable. I don't have more bulbs to test, as they are in the glovebox of my exy (which is still in the shop).

I don't know how to explain this, but it defies physics.

I thought exactly the same, so I tried to follow the cabling from the fuse box, but it was too difficult. Perhaps the wires to the passenger side headlight are redirected and are not as short as your would expect. Especially considering how close the fusebox is to this light.

 Sorry mate, we may have to leave that one to the experts. emoticon
