get a multimeter and with the engine off check the bat voltage.
turn on the car and do the same thing. this will tell you what you alternator and VR is putting out at the battery.

a normal healthy ALT and VR will measure 14.3 give or take at the battery. even high 13.8+ is ok

load the engine with all manner of elec devices and re measure it should not drop too much

if you are way under 13.8 or so next step is to remove and check the VR brushes for minimum length.

a worn VR brush or dying VR can cause what you see.
