Hid Issues....?

[patrick3319]

Any updates?

Well what I was testing has seemed to work so far with no issues/flicking.. I sent JJ a message yesterday and haven't heard back from him. I just assume he's a very busy guy and/or he has already talked to TRS and they're working on something...

Glad to hear things are going better. I pick up my new 2015 on Saturday and want to ditch the halogens asap.

Well some people from these forums have had luck with HIDs working on their 2015... I am also from Canada, so we have the extra element of having the DRL to help add to some of the weird coding and stuff from the ECU or whatever I guess.

I have a week old 2015 Sport and I have Jeremy's kits for both head light and fog and my head lights have worked like a champ so far. I'm having issues with both fogs that I'm ironing out with Jeremy. Both fogs get a blinking effect going then either work or just shut off completely, each side does it's own thing it seems. I've switched bulbs and I thought I found a faulty bulb but then it started doing the same thing again so I don't know exactly what the issue is. Throughout all this I've not had any error messages.

As a side note, Jeremy is awesome to work with and I highly recommend him.

these 15s can suck my butt. LOL

Honestly, hoping some parts come in today, and I'm hoping to have a fix SOON!

They did that just to screw with you is all!

Anybody locally in Minnesota with a 2015 willing to try one of our HID kits? I'd be willing to test a few different options as well.

 

[0212353]

I got in an inline set of resistors today, I believe wired in the manner you are depicting. Same thought process..........need to get some time to text a local here and test it out!

 

[Enlight]

Testing in progress!

I have no idea what the last couple posts mean, but if it makes my fogs finally work then I'm all for it, lol!

One option is to measure the resistance of a halogen bulb as a function of temperature. The RAM computer system might be programmed to be time sensitive. For example, the halogen filament will have a different resistance cold than it will hot. If Dodge was really trying to make it difficult for users to install HID's they could monitor this resistance variation.

Further, more if there is a frequency input, there will be an expected circuit response to the frequency input. The response will be pre-programmed and if the system detects a difference in response, it can cut power, flash or do all kinds of goofy things.

Perhaps the fool proof way to make HID's work would be to basically put a halogen filament or a resistor that exactly replicates the temperature/resistance curve of a halogen bulb. Plug that into the cars factory harness. Then tap into that supply to power a relay harness. Then run the HID system off the harness. The Relay trigger hardly takes any power and should be virtually undetectable by the computer system when tapped in this way.

You would need a damping circuit to smooth out the frequency input to the relay pack but that is easy.

The problem with this is your typical 6 Ohm resistors that say "50W" are not actually dissipating 50W of electrical power. That is their maximum power rating. Simple Ohm's law:

Voltage = Current * Resistance

and

Power = Current * Voltage

The Ram's 12V electrical system gives us:
12= Current * 6omh >>> Current = 12/6 = 2 amps
Power = 2amps * 12 V = 24W

So if you use any of these gold resistors out there or the resistors from TRS, its not anywhere near enough power dissipation to match that of a halogen bulb. You would need double the power or half the resistance at least.

I would be extremely surprised if this setup did not work:
x2 ballasts (non canbus)
x1 Relay harness with a electrical damper on the input to the relay
x4 6omh 50W resitors, 2 on each side plugged directly into the car's factory headlight sockets. Setup in parallel so your dissapating 48W of power Using a spliter on one side to power the relay pack

Run the HID system off the battery/relay harness.

I'd call this the sledge hammer approach as its not very elegant. But it should work and completely fool the computer system. And those resistors will get very hot. But I've had this tested before on some other Dodge vehicles which were doing the stupid periodic shutdown every 10 or 20min and it did indeed solve the problem. I hate using resistors for this kind of stuff because they get so hot. But on really really stubborn vehicles like some Dodge and Porsche in particular, and if somebody REALLY wants it. Its best to bolt the resistors to an good sized aluminum heat sink, and then mount the heat sink to the chassis. Must be bolted down and not zip-tied.


Hope this helps those people who really want HID's! I can build this system for anybody who wants to try it. Or if your in MN let me know! It will use a combination of Morimoto parts and our parts.

With the testing I was doing, we were seeing if things would work with stock bulbs, which after over an hour of driving, my lights didn't shut off once... The only issue i'm finding lately, it started off with a constant buzzing from my relay kit, and now my lights get small flickers in them here and there (but didn't hear the relay buzzing anymore).

My only issue, is i'm not around any of you guys (yourself, jeremy or TRS) to be able to get the testing done, or i'd be there with bells and whistles on to help get this solved!

So, what you really need is one more powerful resistor?

either a more powerful one, or something that more mimics a stock bulb. As Enlight mentioned, it could be looking for other things from the stock bulb other than just resistance

I can build a custom kit for anybody with a 2015. If it doesn't work, you can return it for a full refund.

My relay was buzzing I bought 470cu 35 volt capacitor off Amazon. Put the capacitor on the relay between 85 n 86. Fixed my buzzing

Here's my video showing how the harness works - https://www.youtube.com/watch?v=ng5S8WmY6pQ

[yt]ng5S8WmY6pQ[/yt]

please note, the video is older.....has the older style relays, but....the rest is the same.

There was a weird time where some capacitors where pinned wrong, causing issues......then there where adapters that the polarity was wrong......

In the end, the resistors need to be hot on both sides.

As for the other company playing with resistors to get it to work.....thats my assumption too - just needs to see the right resistance, and if its not.......well.....stupid trucks.

I am actively looking for someone in the ATL area with a '15 to head to TRS for some testing. I have a local guy with one as well.....but its damn cold here and I have no "shop" to be playing in.....ya know? But, I'll freeze my nuts off to figure it out if needed!

I still haven't made it to trying the harness with the stock bulbs, Been cold and rainy here all week. I'm About 2.5 Hrs from TRS, but if someone doesn't figure it out soon, I may have to take a day off and let them test on mine! LOL

do you have a 2015, because thats who is showing the issues. if you're in a 2014 and having issues, theres something else up (that the relay kit may help you)

 

[BlownGP]

What you need is the same power dissipation from a resistor as a halogen bulb. This equates to a lower resistance. When you put two 6Ohm resistors in parallel, the effective resistance is 3Ohms and with a 12V potential across the resistors, the power dissipation is 48W. This is much closer to a 55W halogen than using a single resistor.

A "more powerful resistor" is not quite what you want. You could get a 6Ohm 100W resistor and that simply means it can handle higher voltage, but it would do nothing in terms of dissipating more power.

I can build this kit for anybody with a 2015. If it doesn't work, you can return it for a full refund.

Ahh I see, trying to fool the computer in too thinking you're running a halogen bulb. Which seems stupid why dodge would make this so difficult..

The electronics systems in vehicles these days are so complex, OEM's really dont want people messing with things anymore. Since buying a new truck means several years of warranty, they want to avoid malfunctions caused by non- OEM part use. For example, many people with pre-2009 dodge vehicles have blown PCM's and other electronics when installing HID's. Most of them probably put everything back to stock and said "hey something blew up, fix it under warranty" and then the dealer has to eat the cost.

They don't want to deal with that.

I have no problem with that if the brand new trucks came with HID's from the get go and not the crappy, can't see anything stock lights that we get. Mine is one of the 2015's that can't keep the fog lights working which I'm still waiting on a fix for it from Jeremy. It's ridiculous that a light bulb could cause issues with anything OEM.
