New alternator,New battery,serpentine belt tight and good condition and battery light is on?

Checked all fuses in the engine compartment. Ran tests with the multimeter and battery is getting right voltage.

Maybe try checking for voltage drops; test voltage at BAT connection on alternator, should be same as between pos and neg terminals on battery.

Tested for voltage drop.Resetting light by disconnecting battery. Hoping it doesn't come back on. It has come on before when I stomped the gas and then turned back off when turning off and restarting car. We will see!

Light is still on. I guess it is time to track down the wires to the battery light.
