Ok, so I have a friend whos having issues with his HID kit. He has a Honda Eg hatch. First of all, the kit works, both Hids turn on, its just that on the left side they don't seem to work.
The high nor low beams work. The high beam blinkers on and off, and the low won't even turn on. And on the right side, the when you turn on the high beams the low beams blinker... on the left side we tried hooking or getting the ground wire to touch the ballast but nothing. Could there be something wrong with the wiring or could there be another problem? They're an H4 set up. Any help will do, reps for any advice.

ps; not sure if it matters or not, but he bought a 10k kit. We're not noobs, we just can't seem to figure this out, we've done alot of HIDs installs, so we're almost 100% positive that it has to do with the wiring. When he puts on his stock halogen lights, the left one also seems to be alot dimer.
