So my Low-beams won't turn on, Could a broken fuse be causing this?
 
I have been having trouble with my HID kit, and didn't really contemplate what it was until I put back in my original Halogen lights. The high-beams work just fine but no matter if it's the Halogen or the HID's there is no light whatsoever. I've narrowed it down to maybe a fuse being out, could this be causing it?

very well probably is a fuse or module

There are 2 10 Amp fuses, one for each front low beam light (#14 and 15 in the fuse box), so won´t expect for both to blow at the same time. There is however also a single lowbeam relay, which gets its signal from the body control module. So have a look at this relay first. You could swap the low beam and high beam relay to be sure that the problem is the relay. Both relays are on the junction block, above the fuse box.

I'm thinking it should be the fuses. It's like the low-beam's are not getting any power whatsoever with the stock harness or with a relay, Do the ballast and/or harness require the initial power sent when you first turn on the low-beams? That's got to be the problem. Hopefully I can get a couple fuses and replace them from a NAPA around here.

Does it matter what brand the fuse is? I know I need

F14 - 10 Amp - Red - Headlight low, left
F15 - 10 Amp - Red - Headlight low, right

Update: lol I finally got it to work Frank!, They both burned up at the same time lol. I replaced one with a 10A fuse and I realized I only had 1 so I'm running one of the fuses with a 7.5A, Will that be alright for a day until I get another fuse?

A fuse is there in an electrical system to protect the wires of that system for overheating and to melt the isolation or even to burn up the whole wire when the current would become too high. Using a lower current fuse could only burn that fuse too early, but protects the system well. One lowbeam lightbulb of 55 Watts would draw a current of 4.6 Amps, so a 7.5 Amps fuse should be ok for short therm use.
But still strange that both fuses blew at the same time. Was there any short on both lowbeam circuits? Any problem on the HID kits?

1)I don't think there was short whatsoever. How would I check though to make sure?

2)I still haven't gotten around to hooking the HID kit up again, probably will before it gets dark tonight, I'm excited to see how these new bulbs will look compared to my old ones in terms of brightness.

3) I went ahead and cleaned my battery with some water/baking soda and a tooth brush, hopefully they'll give better conductivity.

4) It is odd they both blew at the same time, I think they were on there since the factory so maybe it was time lol.

The problem was probably the HID kit, so before you reinstall it, i would check all wiring isolation to be ok.

1) How could they have done it if it had been on a separate wiring harness the entire time?

2) I'm not an electrician lol so how would I go about doing that?

I don't know how you wired the whole thing. Are both low beam HID kits not completely separate from each other? That is it making more strange that both fuses blew at the same time. But maybe the bad contacts you had on the battery which was making the lights flash, also caused the ballast to draw more power then normal for the restart every time and caused the fuses to melt.........:confused:
For the wiring inspection, just have a look if there is no isolation shaved through or any other bare metal part which could get in contact with ground and cause the fuse to melt.

The ballasts I guess were separate since they were on the relay. So I'm not sure what caused it. The relay's and the ballasts were hooked up like on any WJ set up.

Update: After replacing the fuses I hooked up the HID kit and everything went well, Now just to see how long it lasts :)
