[QUOTE="NHbeast, post: 1877331, member: 28306"] The best answer I've seen is that weak/old batteries can make late model F150s do strange things. The original battery was almost 5 years old. We recently had a cold snap, -15 F. Truck started noticeably slower the next day after sitting a couple days. Bat voltage was 11.74 after resting. Had the bat tested...failed...time to replace. Got a new OEM bat. Service guy had no explanation for the flashing. He wanted to test for a parasitic draw... I wonder how much that would cost to check? 5 years is good life for a battery. No thank you. [/QUOTE]
