It is the factory battery, The voltage will seem to flucuate between 14.9 to 15 volts, when it flickers, I'm not sure when it doesn't, but it seems to be the same, it was hard to tell in the daylight, sorry.

 

I still say what I said way back in post #4. It's the TIPM and the fact that the heads/fogs flicker but no other lights do would only confirm it IMO. They simply need to stop dicking around and replace it - at least on a test basis to see if the issue stops...

 

I'm with TNtech as far as the voltages go. I just checked my battery voltages, this is what I got.

lights off, engine off = 12.8
lights on, engine off = 12.4
lights on, engine on = 14.4
Lights off, engine on = 14.5

If you are getting 15 Volts, then maybe a TIPM on-board rectifier/regulator is unable to handle the higher voltage and spikes are getting through. I doubt that is the problem, but, 15 volts is high. I still think there is some kind of problem with the TIPM module, perhaps not the module itself but a loose ground, loose connection somewhere (cracked solder joint), who knows. But as Hammer said, if they just put in a different one, they will narrow it down.

 

Totally agree!

 

So what's going on with trucky?? Do they always move this slow in Canada?

 

No repairs nessary, it's normal due to PWM with electrical loads. Since I've seen it on mine, sadly every truck does it. Take your vehicle and park it so your headlamps shine up against a wall, with engine running at operating temperature, and dark outside, leave your vehicle in park, depress your brake pedal and let go while watching the headlamp beam illumination. The flicker you see is what I see, it will flicker once in a while after, I noticed too that all the Ram trucks do that, but only noticable at night. They flicker too when vehicle is just sitting there parked, depending on load and demand from the alternator. My wife's car which is a 2009 will dim the headlamps depending on load and demand from the alternator, but no flicker like the Ram's, which to me is a little embrassing. But that's pulse with modulation, the sad thing is I checked if our work truck, a Ford F-250, had the flicker, but they do not use PWM, which in turn does not flicker. I understand I'm a little picky, but now I know that these Ram trucks do this, it gives me a sour taste about the Ram's, but what do you do?

 

Mine doesn't have any of the added aux luxuries that draw extra amps like the Big Horns and the Laramies. That said, I have an ST and I don't see any flickering with my truck. I'm well aware that it's normal to see the brightness from your lights fluxuate when rpms change though I haven't noticed that either. I checked a few times to make sure ever since this problem came about and it definitely does not flicker so I don't think all trucks do this. It could be a thing with just trucks that use extra amps for the added power and remote features.
