Help!

2005 xk8

I pulled out my LED Hi Beams, as they didn’t have any depth of light and installed a set of HID 9005s with high hopes.

I had been so pleased with my earlier installation of HID 9001 low beams that I was hoping for an improvement over the stock bulbs. Well, I’m baffled…neither hi beam functions, they both have +12v going to the ballasts. The odds of both units being faulty I would image is pretty rare but I do not see where I have gone wrong.

The only question I keep having is that there was an 8” length of cable with a male and female connector on each end which was plugged into the ballasts. I removed them as they were inline connections without any ICs and I thought of them as simple input extensions, maybe I was wrong. Since I mounted everything inside the light housings I didn’t have a lot of extra room for these extensions and I don’t really want to pull it all apart again unless it is necessary for replacement of a component.

Any thoughts as to what I might have done wrong?

To recap:

Fuses good

Power measured at input to ballasts

None functioning lights (both)

Wymjym,

I haven’t done the HID conversion on my 99 Jag, but from what I understand HID bulbs need a separate igniter to up the voltage.

Did that come in the kit?

 

That is the ballast he talks about.

I would double check that the positive and negative are the right way round to the ballast - it won't work otherwise.

 

Hi , been there done that. :-D including the not working bit.

If I remember right it was down to the wiring. Will look up my posting on the subject for you, brb.

 

Here you go. Read 5A and you will, or rather should, see the solution. https://www.jaguarforum.com/showthre...=1#post1025402

Dont forget to let us know if it works wont you??

Thanks!

 

Thanks everyone.

FranckC you were on the money. I reversed the plugs and everything works.

For those that wonder how someone can ‘plug it in backwards’;

the ballast has a female receptacle with a locking tang, the jaguar plug has the counterpart on its plug…so I thought the normal approach would suffice, it didn’t. I assume that when these are manufactured this small point isn’t of much concern. Never the less, they now function.

I’ll report back next week after I get a chance to try them out at night and make some adjustments. I can tell from the pattern on my wall they are a major improvement compared to both the original bulbs and the LED conversion I did earlier.

I guess the LEDs will finally reside in my fog light assemblies.

Great stuff. I can imagine how it felt when they did light up.

People have asked me why did I not install LED lights and it was because of reports from people like yourself.

The HID lights make a massive difference. Its one mod I highly recommend.

Thanks for letting me know it worked. I do a lot of writing about our XK100 cars and its always good to get feedback. Thanks again for letting me know it worked!
