Hey, mine is doing the same?
1998 f150, 5.4, Lariat power everything. 160,000 miles......
Took it to VIP and the battery and Alt test came back GOOD?
But sitting at idle in the driveway, it starts to flash the battery light after driving it back home? When I push on the gas, ity goes away, and the Alt Gage reads half way way in the good?
Maybe Alt gets weak after it warms up??
