2008 ford f150, 130,000 miles, battery light comes on periodically but battery, alternator, and connections test well...recently replaced throttle body however.
Any recs from the OT truck owners as to what the problem might be?

Anything less than a King Ranch 250 is not worth the OT's time.

Problem solved.

What's the battery gauge aka voltmeter doing when this happens? Thats will provide you a clue. If it shows low volts, it could be the alt. If it is dancing and dipping, it may be a bad ground somewhere.
Electrical problems suck and can be difficult to pin down

1. alternator likely needs replacement. the light comes on when the alternator is not charging the system
2. could be wiring/connections
3. if everything is indeed ok, you may just need to reset engine computer

if it was the battery you would have starting issues
its the alternator, its not putting out enough juice so the light comes on.
the engine draws power from battery when alternator isn't charging right and light comes on when battery gets low.
when truck sits the battery reserve power builds up some, letting it still start ok.
bring the truck to the shop, or the alternator in to an auto store and have it tested.
might also be bad main wire connections to battery or alternator but most likely its just a bad alternator putting out "some" power for idling, but not enough when driving

Put a piece of black tape over the area where the light shows
