I just finished installing a HID kit. Everything works good until I start the truck. When the vehicle is not running they lows work just fine. It is when the truck is running that the low beams will not turn on. Anyone else have this problem? As for wiring I just plugged right back into the factory harness.

 

What type of HID lights are they ( power from the factory headlamp connector, or power from the battery and the headlamp connector is for the trigger ) ?

When they don't work while running, what position was the headlamp switch in, when you started the truck ?

If you start the truck, then turn the headlamp on using the switch, do they work correctly, or is this the same symptom.

 

I am getting my power from plugging directly into the factory wiring harness.

If I start the truck with the lights off, then turn on the lights, the lights will turn on for a few seconds then turn right off. Turning them to the off position and then turning them on again does absolutely nothing.

What I don't get is that they work great while the truck is not running. It is when the truck is running that they don't work.

 

09s have a very differnt setup. The smart junction box has the ability to disable cicuits if it sees to large of current draw. If you are not using a kit with a relay i highly suspect this is your problem.

 

You beat me to it, I was thinking FET operation if they were drawing power direct from the headlamp connector.

I can only take a SWAG that the current inrush for power up on the ballast looks to the FET as a short circuit condition, due to ramp up.

 

problem i have is that the 2009 factory headlight harness has 3 female prong openings....and the ballast has two prongs? how do i make this work?

 

Just a related note to as you live in Alberta. Make sure you disconnect your daytime running lights as well. You should also not keep your lights in Auto ON/OFF. The short light up time before you start your truck will shorten the life span of your HID's. You'll need to pull the fuses for DRL and highbeams if you don't have a bi-xenon kit.

 

Guess you got a kit without instructions.

You have a low beam only kit, which means you will only use the pin for the low beam element on the bulb connector to trigger the ballast or the relay.

1 word of caution, do not plug the ballast directly into the bulb connector, your 2009 has a FET control circuit that will shut off if the AMP draw is too high.

Too many of these overloads on the circuit, and you will be taking a trip to the dealer to have the SJB ( Smart Junction Box ) fixed.

 

Is your kit single beam, or bi-xenon? If single, you're going to need to get a relay, with the low beam as the trigger, as SCULLY said.

If bi-xenon, your kit should have came with the relay box that powers the ballast as well as controlling the solenoid in the bulb.

FWIW, all aftermarket ballasts I've seen have a 2 prong connector for power, and 2 tube connectors to power the bulb.

 

alright well i got the HIDs to light up just fine with my low beam kit. I "piggy backed" the lights and basically i no longer have high beam but who cares. Only thing is that when the truck is on, the headlights have a slight flicker, not a flicker as in on and off but like the beam is moving up and down somewhat hard to explain. i found these on this website... think it might work?

The bulb is moving up and down?

So, you bought a bi-xenon kit (since you mention high beams), but it didn't come with a relay box? Now, you "piggy backed" it to where the low beams come on, but the bulb flickers? Does it move when the truck is off? Does it move if the truck is on, but sitting still?

What kit are you using?

As for the cancelers, unless you have a light out warning, you shouldn't need them. What you need is a relay box.

 

here's whats weird...they are Xentec kit. i have these on my 2003 Mach 1. They worked great. I also recently purchased a new set of Xentec HIDs for my mach 1 bc one ballast blew out and my new air of Xentec has this flicker. I put back my old Xentec kit and that set works fine. I assume it is just a bad batch of ballasts???
