Judging from what I've seen and heard in these forums I would imagine that you'll find some kind of issue with all makes and brands of autos. That said, no pun intended but good luck finding a flawless anything much less a perfect truck in todays world. I'm a firm believer in the phrase 'they don't make em like they use to'. Yes the technology has greatly improved but quality has gotten much worse in my opp.

 

I totally understand that, it's true, but admitting that there is a problem, then saying it's normal is total BS.

 

I think we all know you will get some minor amount of flicker in headlamps with AC and different electrical loads cycling and what-not. But what you are describing doesn't seem normal at all.

If you can, get some video with your phone or something when it's happening.

 

Definately for sure, it was funny, I was in the drive through at Timmy's, my headlamps were flickering/pulsating, I noticed the truck in front of mine, a new F-150, and a new Ram 1500 in front of the F-150, being dark in the morning, which is very noticable, and no flickering at all out of the 2 trucks infront of me, but mine flickers away. Funny thing is they looked back at me like I was flashing them with my headlights, it's pretty embrassing, but Chrysler says it's normal. I understand the electrical load of all the accessories being on, like A/C and heater motor.
But this is very unusual.

 

K if at all possible and the time window is long enough, put a voltmeter on the battery while it's doing it. Not absolutely neccesary just if you can.

 

A voltmeter is too slow to catch pulse modulated voltages. If you know anyone with an oscilloscope (try electronic repair shops, radio, etc, anyone that has access to an oscilloscope). Put the scope leads on the input to the bulb or the output of the TIPM. This will record the voltage and all of the spikes that are causing the flickering. The dealer and Chrysler are blowing smoke up your a** if they are not even willing to monitor the voltage to the bulbs. There is no other way to tell what is going on. What is probably happening is that the TIPM is sending a series of pulses of one width and interspersing them with shorter pulses. This will show up on the scope. As an electrical engineer, I've done this kind of stuff many times.

 

That's sounds right to me Pedro, I will try checking it with the scope, I still do believe it's the TIPM at fault, I noticed the issue was after the torque convertor was replaced, and then I found the Y ground cable at the back of the engine heads was not clipped in the proper location, which is suppose to be clipped on the heat sheild that is located right over the transmission bell housing, bolted to the firewall. When I found the ground cable, it was just hanging there, and not clipped on to anything. One of these mornings I will record the pulsating when it happens, and to show when it is happening. Thanks for your help Pedro.

 

I wanted to know source voltage at the battery....not the bulbs or TIPM output. One thing at a time. I am well aware of what the TIPM is doing.

 

I'll check the source voltage at the battery, while the headlamps are performing the flickering.

 

Yes it is, but that too happens just as much with other makes as well...not taking up for Chrys by no means. You have a right to be frustrated and I'm not one to talk when something like that happens to me. About the lights... this may sound somewhat kindergarten but could it possibly be a ground shorting out somewhere...like a loose or bad connection or corrosion in a connector. If you checked female connection at the bulb and found the voltage fuxuating, you still won't have the reason why...or would you? I'm just guessing so don't count on what I said, lol EDIT: this story kind of reminds me of how motorcycle headlights flicker as there coming at you...it's really agravating...makes me think it's an emergency vehicle at first sighting.
