Notice that emd f7 has a interest machenism , you can change the electric current from series-parallel to parallel shunt(1-4) Do ALL the resistors remove from the circuit when I push the power handle into 8? How long can it holds before the resistors burn out in real life? I dont know F7 very well , can someone explane this? (btw the manual transition function is loss , it would be more playable if have that)
