    HID's not working.

    Hey Guys,

    Went to fit my HID's today but can't get them to work. Do I need to hook them directly to the battery? Or should they just be plug and play? I am using H1's, although that should not make a difference.

    Stupidly I have misplaced the instructions, although the translation on them was very poor. for some reason though the rubber gromet that is on the wires connecting the bulb to the balast has 4 wires going through it. Two go directly to the bulb, the other two have spade connectors at the bulb end and a H1 female connector at the other. I can't work out what its for. I'm thinking that might not be needed for my car.

    Please help!

    its plug and play, you dont actually need the spade terminal wiring so you can bin it, connect the rest up and it whould work fine.

    The wires with the spade connectors fit to the orginal bulb's plug and power up the ballast box. You don't need to use them as the pulg on the wiring loom fits the ballast directly, however make sure it's polarity is correct.
    Tell me what you've done, not what you're going to!

    Yea I have tried plug and play and that didn't work for either light. So could the wires be the wrong way round? How would I test for that? I can only connect the original loom onto the balast one way.

    Ahh am I right in thinking that the additional wire I found should have been contected between the original wiring loom of the car and the balast? Thus inverting the cable. I will have a go tomorrow.

    I tried reversing the + and - on the cars original wiring loom and connecting it to the balast, but still I am getting nothing out of either of the bulbs.

    Could the balasts be defective? Should I try connecting the balast direct to the car battery to test if they work?

    Yes try and connect the ballast directly to the battery.

    OK both ballasts and bulbs work when directly connected to the battery. I have tested the voltage on the wiring loom, and its 11.6volts where as the battery is 12.4volts. I don't think that would make much of a difference. Do you recon its worth checking the amps on the loom?

    Connect the ballasts up and run the enigne and then turn on the lights to see if they fire.

    Factory fitted xenons usually only fire with the ignition on (which usually means that the engine is running).

    Yea I thought of that originally when I was fitting them. I'm gonna check the amps later when I finish work.
