Hello, I’m new to the forum and was wandering if anyone has had an issue with flickering pulsing headlights/dash lights? So far I have replaced a list of components and still have the same results. I have replaced the main ground wire off the battery. Replaced battery and alternator. Checked all the body grounds and most of the wiring on the truck from bumper to bumper. I know it has to be something simple that I have overlooked and can do myself in my garage. I figure I would check here to see if someone had the same problem and was able to fix.
