So I've had my hids professionally installed in February on my 2012 sxt. Recently they won't turn on at all and if they do a small bump and they would turn offf.. I looked under the hood and found a yellow fuse connected to the battery melted. The shop I had them installed at is closed today so I'm just looking for some info as to what the problem may be before I take it to them tomorrow. Any info would be greatly appreciated.

my money would be on a bad connection at that fuse block. HID headlights shouldn't melt a 20A fuse (each ballast should draw 3-5A, IIRC). If there was not any other issues with the setup, I would solder in a new fuse block and call it a day. You could put in a larger fuse also, but probably no more than 30A. Anyone else with aftermarket lights want to chime in?

There has been threads concerning HID kit installations, but it's worth mentioning again: make sure you're not using the + terminal under the hood to hook up the HID lights, the safest way is to attach the lights directly to the battery terminal. I remember reading that there's been cases of ECM(?) circuitry getting fried, leaving drivers without any sort of signal/brake lighting in addition to no lights from their HIDs.

I have thick gauge wiring running from the battery to a separate terminal/fuse block under the hood, and that's where my lights are hooked up to (and any future additional accessories).

I agree with JRod_141. Poor connection causing heat at the location = melted plastic. Replace with a good connector and probably all will be well. The statement you made a any bump making the lights go out indicates a loose/poor connection.

Thanks for the replies guys. In response to MrGreenHeart the fuse that is melted is connected directly to the battery. I will keep you guys updated on what's going on tomorrow when I bring it into the shop.

Sounds like a bad connection if they have been turning off when going over bumps. It loosened and made a high resistance connection that drew excessive current and melted it.

That's happened to me before. Turned about to be a poorly made relay harness. Just look into getting a new one from a more reputable place. I wouldn't try to fix that harness since it's already looks to be subpar.

Yea it was exactly that. They replaced it and everything seems to be ok now.
