Just bought HID conversion kit with H3 bulbs and tried to follow the chinglish destructions without much luck. The instructions say to connect the "blue" wire and the black wire to original sockets. Problem is their is no blue wire so I assumed the red wire was the one. I connected it up to the relay the same as the quart halogen lights were operating on ok and the black wire to earth and switched lights on and they operated while I walked around the front to
check and then I switched them off.
Went for
test drive once it go dark and switched on
driving lights and they operated for about half a second and then went out.
It appears on checking today that both relays (one each for each driving light) is now dead. Has the high voltage that the ballasts produce somehow caused this and if so how do I rectify it to stop it happening again.
Any help will be apprectiated.

When I put them in my falcon headlights I used no relay and simply wired the ballast as per instructions. The wattage and amp draw are supposedly less than the std lights draw so this should not be an issue. My lights ran fine like that for a couple of years but I reverted back to halogen when one ballast gave out and i always reckoned that the light refraction from the different length globes made them a
hazard to other drivers as the light wasnt designed for that length of globe.
Any way getting off the subject a bit mine ran fine with no relays.

I converted a hand held spotlight and had the same problem. The light source was no longer at the focus of the parabolic reflector. I overcame this bit inserting washers between the globe housing and the flange on the globe until I achieved the correct focus. From memory about 5 mm was required.

PS Relays not needed as HID lights are either 35 or 55 W

I have H3 HIDs wired into my IPFs. I used the original IPF loom, cutting each of the twin wires leading to the lights and connected them to each of the ballasts. I then connected the live feed from the relay, which used to feed the lights, to each of the ballasts. The H3 HID globes have the two wires connected to the ballast, red and black therfore there was no need to connect to earth. In my case, the relay is before the ballasts, switching
battery power to the ballasts when on high beam. I only have the single IPF relay and a 25amp fuse between the relay and the battery, and have no problems at all. The instructions that came with my kits only showed, connect the ballast to positive and negative, and the two wires out of the ballast to the globes.
Hope this helps
Mike

The Ballasts will each have 4 wires. 2 12v wires and 2 silicon ones for the bulb. These should be self evident as they are special connectors and can't be interchanged. MAKE SURE these are plugged in before connecting the balasts to 12v. They generate up to 22,000 volts enough to give you a big wack, damage electronics in your car or screw up the balasts or all of the above.
Most ballasts don't mind having the 12v wires around the wrong way so you shouldn't damage them if you do this.
The main issue is that despite the fact that they only draw 3.5 amps when rinning, they generally draw 15 to 18 amps for 5 - 10 seconds on start up ( when they are humming.) This can blow fuses or light wiring / relays. Also if the wiring is not up to the job or you have a flat battery they will not ignite reliably or at all. This is usually seen as a flash for a second or so. Make sure the wiring and fu7ses are up to the task

I just replaced one relay and tried an old spot light from the shed and it works fine. The HID lights have definitely blown both relays. These relays were 30amp hella ones fitted with 30 amp fuses and I had no problems with the IPF 900 lights with 130watt bulbs until I fitted the HID bulbs and ballasts.
Not sure where I go from here.
Thanks to those who replied.
