10a fuse burns out with HID's. Question... - Toyota 4Runner Forum

alext72888 · 01-22-2019, 08:50 AM

Recently I insalled xenon depot's xtreme HID kit for the 4runner. (low beam)

I didn't hook them up to the battery.

my 10a fuse keeps burning out and one or BOTH lights stop working.

If I use the supplied wiring to connect the lights to the battery, I feel as though this might circumvent the issue.

To those of you who have hooked them up to the battery, by question is this:

Will the lights still turn off when I lock the car?

Right now I just keep my low beams on all the time, and they simply shut off when I lock the car. Does this still happen if they are hooked up to the battery?

Thanks.

What you want is a relay. I'm surprised the kit didn't come with one. Hook the lights up to the relay, run power to the relay from the battery (you'll want to add a fuse to this wire) then hook the relay trigger terminal up to the stock wiring.

The kit should have come pre-wired with a relay. Yes you have to hook them up to the battery.

what fuse is burning out? if you have the 35W set it shouldn't blow any fuses even if you don't use the supplied relays. the 35W kit should work fine without a relay.

yes if you use the relays they will turn off like normal, but i think you have a separate problem from needing the relays if you are talking about the 35W kit.

i had this for maybe 6 months, no issues with NO relay.

The XD kits from Xenon Depot do not require the use of relays. Mine have been running off stock connectors since I got them. They work great and I have not had any issues. As far as fuses blowing, I would contact them and see what they say. It sounds like something in the ballast, bulb, ignighter, etc. may be defective.

I’ve always gone with DDM tuning for hids I have a set of 5k for my low beams. They are cheap and the company backs them with a lifetime warranty. Probably come from China.. had mine in for a couple years in negative degree weather and in 100 degree weather. Haven’t had a problem yet just order the right model so they don’t flicker or cause other issues.

The factory wiring should be able to support a 35 watt hid kit no problem… even a 55 watt hid kit should be pulling about 5 amps or less. You might be right on the breaking point. If you have an current clamp or amp meter you can measure the inrush and RMS current draw, perhaps you have an issue with the ballast.

Either way, run a dedicated circuit for the lighting using a relay and just connect the on/trigger wire to the existing factory wiring should solve your problem, but for most installs, isn’t even necessary.

+1 for DDM tuning, I always run their premium ballast and bulb, the quality for the price is pretty good.

I see. I've always used the Morimoto kits that came with a wiring harness with a relay. Never had a single issue but they are not the cheapest.

I bought mine and installed Dec.20th 2018, same setup as yours and I had to replace my fuse this morning. I will follow your suggestion.

I'm curious if the 4R uses the same wire harness as the GX. GX has HID lights OEM. Balast is built into the headlight housing. My guess is that they use the same wire size and relay for all of them even if the harness is not shared. So they should be sufficient for a similar draw aftermarket HID setup if that's the case. Or you could swap in GX balasts, but that'll require a bit more customization.

or more simply, the factory headlights are more than 35W so 35W ballast should be fine in regards to wire size

Both left and right fuses burnt out while starting my vehicle this morning. I know there is a large surge of electricity required to ignight the HID lights. Perhaps the act of using the starter with this causes the fuses to blow?

I'm going to experiment by only turning the lights on when the car is running.

I received a response from Xenon this afternoon, and it is as follows:

Hi D****,

Thanks for your email, sorry to hear about your issue. I believe with the colder tempatures the ballasts are required a bit more amperage on startup which is causing the 10amp fuse to blow. With that being said I recommend replacing them with a 15amp fuse and you should be good to go. The wiring and harnesses are rated at least a 15amp fuse so no worries there.

Regards."

Can a Toyota Guru validate this please?

So I called into Xenon to validate the email and was basically asked if ran the supplied wiring that came with the lights to the battery. He said bottom line it should be hooked up to the battery.
