Or something else?
2003 F150 8 cyl. 5.4 LDriving home, the red battery ion appeared in the dash. I didn't really notice any problems with how it drove and I made it home ok.
Driving back (20 minutes), I really didn't notice anything but the ABS and red battery icon appeared.
Driving home (20 minutes), the radio was intermittent. The radio went off altogether. The truck began "missing" or running poorly. I made it home, parked, turned off the engine, tried to turn it over, and it made the dreaded clicking sound.
Any help appreciated!
