2001 mitsubishi montero sport 4wd, 3.0 engine. Battery and brake lights are on, the serpentine alternator could cause this problem? When reaching the 2,000 RPM the warning lights for the charging system and brakes is turned off, when the RPM come down again these reappear.
I doubt it is the belt because if the belt is slipping you should hear it.
The alternator could be about to crash and not charging at lower speeds.
You would check alternator output to find out.
The battery and brake warning lights are on the same circuit.

So where all 3 Alternators returned & tested?
Do you have wiring diagrams out ready to go
& a volt meter to start your testing?
