Put a voltmeter on the battery posts and look at the voltage with engine running. Also from the output of the alt to ground. That voltage will make a starter click for sure.
I never heard torque pro reading low. Let alone 3vdc low during normal operating conditions. The volt reading is the voltage from the OBD2 port.
Hit your alt with a hammer. If your voltage goes back to normal, your brushes are worn or were stuck.
