Welcome to the forum.
Put the vehicle in Park, run it at 1500 rpm or higher, apply the full load, and read the battery voltage. You'll probably need a second person to do this........and holding it steady at 1500 rpm is almost impossible..........so just keep it above 1500 rpm.
If the voltage remains above 13.5V, the system is functioning normally.
