relaying headlights
« on: 19 December 2012, 16:48 »
goood evening.
 i have hella quads with night breaker plus in the projector and osrams bulbs in the sidelight.
to my knowledge they are all aligned correctly.
but the output seems pretty poor.

i read about relaying them but will that really much difference or is that a mk2 thing.

anyone do it to theirs??   or is it just better and easier to go with some HIDs?

cheers

Check the voltage on them with the lights on. I have a full kit available for sale. Pm me if your interested

I was finding my headlights were ending up at 9v, which wasn't great for output.

Have a read of this:

http://www.matey-matey.com/uprated_headlight_wiring.shtml

I've been looking into this relaying business myself but I'm wondering whether I should find the problem? It says in the article that because the loom is too long the voltage drops but surely it wasn't like that from factory right?
Are there any earths/positive connections that can be remade to get this voltage back? (if it can come back)

The voltage drops not because the wiring is too long but because it is too thin.
Thinner wire has higher resistance than thicker multiply this by the current which is fairly high since it all low voltage gives you an impressive drop in voltage... add a few junction points (plugs, switches, etc) and it goes down even more.

And yes, was like that when it came out of factory. However ground connection can corrode, making it much worse still...

I suppose back in the 90's it was the norm plus there were no HID's or Xenons to compare it to so new Golf customer's wouldn't moan!

Think a good earth clean up is in order first, the ones under my battery I replaced because of corrosion so I think the other hidden ones must be in the same shape.

Thanks for the info itavaltalainen

lol. okay ill try and get out in the rain today and check the voltage. ill have a read up on that page too.

cheers for all the info guys

just been out with multimeter.   with the engine running the sidelights were at 13 something, the fogs where 12 something and  drivers side dipped was at 10 something and passengers side was 11 something.

all seem pretty good really.

is it worth doing to the dipped beam?

I thought the headlight relay'ing thing was a mk2 problem, not a mk3 problem?

You only ever need two tools in life. If it moves and it shouldn't use Duct Tape. If it does not move and it should, use WD40.

Definately. You want them at around 13-14v for maximum effectiveness. Dont forget to put a new earth in too.
