CAR'S BATTERY LIGHT ON WHEN IN GEAR AND A LOAD IS PUT ON THE CAR

2001 Ford Focus • 160,000 miles

When I put the car in drive the battery light comes on
a few minutes later sometimes goes off when the rpm
climbs back up above 1,000 rpm's the battery, starter,
alternator and wiring still looks good no burnt wires.

Cleaned all ground with sand paper and checked coil
wires and fusible link to the + cable all max fuses are
good relays are not burnt or damaged but I have never tested one.

I am puzzled something is draining my battery after a period of time
could someone help me to figure this out?

Check alternator belt tension if okay-have the computer controlled circuit of the alternator field generation checked and tested
