My problem is, I installed a set of HID light in my 08 300C. Those HID did not work of the factory head light plug. So I had to put a couple of relays in between to insure that the trans are getting enough voltage and current. Pins 85 & 86 are getting trigger from the head light plug. That plan worked fine, however, when I drive, once I push gas a bit over 2300RPM lights start to flicker and I can hear the relays buzzing.
Any suggestions, solutions, or opinions?

Hey man you may want to check the grounds if they are even grounded!!! ------------- How far up your ass does your head go??? Clay Cole

There are two relays.
1st relay: 85 goes to (-) from head light plug.
86 goes to (+) from head light plug.
30 goes to (+) fused power (12V).
87 goes to (+) input to trans.
the other relay is the same.
each trans has a chasis ground wire, and a positive side coming from the relay set.
I noticed that when the voltage goes up to 14.2V relys buzz.
When a relay buzzes, I grounded pin 85 nd nothing happened, so I jumped 86 to 30 and buzzing stopped.

When the relay is buzzing, what is the voltage between 85 and 86? Try grounding 85 to the chassis of the vehicle.

what kind of voltage are you getting between the two leads on the factory bulb connector with the original bulb installed and with nothing installed? is the halogen you replaced a 9006? does your car have an automated system that tells you when a brake/headlight is burned out? a relay shouldn't be necessary because almost all hid ballasts require less power than a conventional halogen. most HID systems require only 35 watts of power. most halogen bulbs are 50 to 65 and sometimes even 100 watts. i'd get rid of the relays. ------------- Twisted Performance

When light is on: Voltage is 10.5V between 85&86.
If I disconnect the relay, voltage will be 14.2V @ the head light plug. I replaced 5 relays and got same results.
This is what I thought and that's waht I did. I pluged the factory head light plug in the trans plug but they didn't work. That's why I had to go witht the relay way.

i ask because most high end mercedes benz (daimler) without factory HIDs will completely cut off voltage to the light socket if it does not detect that headlight bulb's resistant in the circuit. I don't know if the chrysler division of daimler adopted this circuitry or not to your car. when i had this problem, i completely bypassed the headlight circuit and triggered them to come on directly from the headlight switch via relays. ------------- Twisted Performance

It makes sense what you said about that type of circuits! But there was voltage even though the plug was hanging free of load. And the biggest problem in this car is that the output of the head light comes from an integrated relay module. So, you cannot get to turn on the headlight but with the switch. I wish there was a relay for head lights in this car.

Get all 12 volts from the battery. Use the neg. trigger from the factory harness only.

Actually,,,the answer is quite simple..You need relays with resistors on them and the flickering will go away. We actually have HID's that have built in resistors and plug the ballast in direct without any flickering. Before that we had relays that had the resistors on them and wired them. From our experience HID's always flicker without resistors just like BMW, MERCEDES, and CHRYSLERS!!!! We did one today and no problems. We sell an average of 40 sets a week and dont have any problems with our special ballast.

also 32v ballasts!

ok i had a problem with a acouple of chevys and also with a 3ooc the problem was that when installing the bulb into the ballast the connector dint connect properly so the hids dint turn on but wat i was told to do was to connect the connector backwerds i know it sounds dumb cause it only goes in one way but it works a little trick try it
