I know that this has been done to death, but..

There are two problems if you ignore the legality aspect.

Canbus compatibility
EMF interference causing problems, primarily wiper motor failure

The first issue is a avoidable by using a canbus compatible ballast or error cancellers.

The second appears more intransigent with various theories as to cause and solution. One thing that occurred to me was that suppression of the EMF by screening of the HT cables leading to the bulbs might be effective, on systems with ignitors local to the bulb the EMF problem is non existent or at least minimised. To this end I have installed a canbus compatible HID kit to my wife's A3 with three layers of steel braiding covering the HT cabling with an over covering of braided heatshrink, the connectors are also triple wrapped in over braiding.

it remains to be seen if this is an effective solution and I know that I risk wiper motor Armageddon, however it has to be worth trying, so I thought I would.

if the wiper motor goes to the great scrapyard in the sky I will keep you posted.

One thing I meant to ask was about the common earth apparently shared by the dipped beam and the wiper motor, does anyone know where these terminate so I can relocate one or t'other as a secondary precaution.

Thanks !

Cant you just take the negative's right from the ballasts straight to the battery? and also shield them?
 
Maybe, but I would prefer to reroute from the terminus of the circuit in case there is anything clever going on that I am unaware of.

I just thought less cable on the way back the better, but im sure someone else will know if it will work, or where it is xD
 
I didn't think there were any "kits" that worked out of the box? If at all?

Or you could just buy a kit from welldone and forget about it..

Smurfworth, there's still no guarantee your wiper motor won't blow at some point because of the kit you fitted! It could be operating fine just now, but it might still cause issues in the longer term.
 
i don't get HIDs all they do is annoy other road users by being unsafe

There are bulbs which are brighter than HIDs in a non projector housing that don't spray the light pattern in a full 360 degree way

The fact they aren't legal is only a minor aspect, compared to the mindset of the people who fit them. They're no better for night driving than a decent pair of bulbs! I don't use my main beams on unlit roads at night because my road legal dipped bulbs are more than sufficient

in a projector lens they are fine and dont blind anyone actually.
And yes they are actually brighter than normal bulbs. the fact is in the lumens.

so with these combined, they are better for night driving than a decent set of bulbs.

I said non projector housing, and there may be more lumens but id argue that half are being scattered upwards to the sky, hence blinding oncoming traffic. my bulbs are as bright as any HID cars I've passed and they're Halogen

They may be better for "YOU" but thats an opinion of an obnoxious driver who could care less about other road users

not sure how i'm being 'obnoxious' but clearly all these manufacturers which HID come OEM are aswel.
these companies sure couldn't care less about other road users.
 
There are NO OEM HIDs for a reflector housing as its illegal, in order for HIDs to be OEM they need to be in a Projector housing with washer jets

HID kit suppliers are supplying an illegal product if its use is in a Halogen reflector housing, Xenons are factory OEM HIDs

Smurfworth is using a HID from Welldone with no high voltage cables.
No high voltage cables means no interference.
No interference means no wiper motor problem.
His wiper motor is completely safe.

Google about it & you will find hundreds of people using this HID without high voltages cables for the last 5 of 6 years.
None of them had any problem with the wiper motor. Is not a coincidence.

And hear comes part 2 of the sales pitch,


HID information and discusions should be made a sticky as these threads are getting pointless and turning into sales pitches/arguments.

There is enough info by simply typing HID into Google. I may be speaking out of turn here but just a thought, all the Facts, theorys and open discussions on HID's should be in one thread.

Seduce my antiquated nautical heavy duty footwear.. Please give it a rest.

Back onto original topic, does anyone know where the common earths for the lights and the wiper motor terminate?

That aimed at me?

And just earth the HiDs directly to the battery, it is yet another theory which has being discussed.

Jonny,

It is my frustration that a simple posting and request for info has degenerated into a **** fest.

If you read the thread you can see we have already discussed direct earthing and I have actually managed to fathom out how a DC circuit works, however having spent years commisioning and fitting ECUs I am aware that quite often the power and earth to a circuit are required to be routed via a device, rather than direct.

Hence my question.

Dave
 
I know, hence my post aimed at Mr Well Done who jumps onto ANY thread which touches on HiDs.

My post was not aimed at you (unsure if you are aware of this)

Anyway i cannot answer your question on where it is directly earthed to,


Jonny.
