hello. Im having a problem with the power with My CW-80 Transformers. Whenever I run my 671 turbine with the whistle tender. The green light flashes when i press the wistle button. this only happens when i use the whistles with the old AC motors, but when in neutral, the whistle works just fine, which makes me think that the engine and tender are both drawing to much power. but i don't know if something is wrong with my transformers beacuse if I ever get a dual motor AC locomotive Like the early postwar F3s or an FM Trainmaster, im worried that they will draw to much power also. thanks.
