lights flickering

i've searched all can search. about a month or two ago I replaced my alternator and within the past couple weeks i've noticed the lights flicker. doesnt matter if i'm idling or cruising at 75. any ideas?

I'm curious as well, I have the same issue and thought it was an alternator.

Not sure if this is your problem but on my 04 sd mine was doing the same thing. If you tilted the steering wheel they would go out completly. I found a wire loose under the steering column cover, and when it moved it was loosing connection.

in my hours of reading common 6.0 problems for the 10th time in a couple months, i did however find a posting that it could be the tensioner assembly. hopefully thats not the only option....

I was leaning toward the loose connection thing for a while, but I thought it was under the hood. My motor has been in and out of my truck more times than a porn stars vibrator been in her pu$$y!

Sounds like quite a few!

LOL

Check grounds.

i checked grounds and hooked my livewire up i forgot it had the battery volatge meter. getting 13.5 to 14v while idling and running wide open.

ill check them with a DVM later and see what each battery is reading.

ok update. i've had the alt checked its good. and both batteries are good. primary is reading 13.5-14.5v secondary is about 11.5-13v both KOER. still flickering.

My mechanic just solved my dead battery issue. No lights flickering. Just dead battery. One day my batteries died. I had them charged then they died again. I was also experiencing a blown fuse each time before the batteries died. Fuse #45. It's a 10Amp fuse. I replaced the batteries and a new alternator. Still the problem persisted. The mech found a wire in the stealing column had been rubbing intermittently and shorting the fuse which is part of the charging system for the batteries. The wire that was shorting was from the tow button on the gear selector handle. But the short was in the column. Each time I moved the gear selector arm (automatic trans) it would move the wire. Sometimes shorting and sometime not. What a nightmare. I have a 2003 ford 6.0 diesel 2wd excursion.

Flickering lights, Sure sounds like a short.. Glad you got it fixed..

Have you checked tbe wiring in the steering column like i mentioned? That was the cause of mine, and it seems a few others..
