So i have 4 hid lights (the kregan type, not from kregan) all 4 bulbs are good all 4 ballasts are good. when i turn them on, sometimes they turn on, sometimes they dont. I have 14g positive and negative running 1 set. another 14g positive negative running another set. so 2 are running to one switch. one always turns on in the pair (is not consistant to which one turns on) i can sit there turning them on and off and sometimes i can get them all on. sometimes not. any ideas??
