I am having trouble getting my HID kit to work with my aftermarket fog lights. The fog lights are H3 and just have a simple relay wiring setup. When I plugged in my HID H3's they won't come on. It makes this buzzing noise like they're powering up when first turned on but then stops. Also if I only have one of the fog lights plugged in it will come on. Anyone know what I can do to solve this problem?

 

possible ground issue? you say that when you unplug, say the right one, the left one works? what about the other way around, unplug the left one does the right one come on? have you swapped the bulbs around to the other ballast to make sure that the bulbs are good? are you getting at least ~12-14 volts at the plug? swap everything around and see if the problem follows.

 

Do they use the same ground? or are they ground separately before the relay?

 

I know when I unplug one of them the other one would come on, I can't remember if it would work vice versa. I'm not sure what volts they are getting because I don't have a meter. I'll try swapping everything around.

 

No they don't use the same ground. They are ground separately at each foglight.

 

Send the valence, lights, harnesses and switches to me. I'll sort it all out for you, and let you know what's wrong.

 

well recheck the grounds on both of them. make it short as possible but to some solid metal.

 

STANDS ISSUE!

HIDs require huge current capacity to light off and often can exceed the factory wires (the gauge of wire causes a high current drop on startup). This is why you can get ONE to light if the other is NOT plugged in.

First run through your wiring harness and make sure there is no corrosion at any terminals (even relays). If everything checks out there, then you will probably need to consider running larger wires to the HIDs (often times HID kits come with wiring diagrams on how to setup a standalone wiring harness).

I personally didn't have any issue on my 04Silv (I have HIDs in my Lows and Fogs) but I don't know if the wiring is exactly the same between NBS and OBS. I did however have an issue trying to light the HIDs off with my bench-testing power supply as it is rated for 10Amps (then kicks into overload), and I found that ONE HID bulb/ballast required close to 9Amps to start. Once up to temp, they drop to only a few Amps.


Edit: see here http://orca.st.usm.edu/~jmneal/tiburon/hids.htm , about half way down is a diagram for doing a higher capacity harness

 

Alright I'll check my grounds again and try running larger wires to my HIDs and see if that'll help the problem.
