Here's the deal. This past week I've noticed that while my truck (E99 f350) is idling every light that is on is flickering/pulsating. Its really annoying to say the least. I've done a good amount of searching and have come up with this; Grounds on both batteries are cleaned up and good, alternator is only 2 years (~10k miles) old from pepboys, Its puting out 14.2-14.7 volts according to my multimiter, batteries are 2 years old as well. Really hoping that I don't have to replace my alternator. Going to get it tested tomorrow. Any other ideas would be appreciated.
