What are you doing when this occurred? My tests indicate Engine only flat surface high power current to be less than .4 Amps on the BB gold motor, the round jet motor would be close to the 0.7. As you add train load(cars, grade etc.) this current draw will increase towards the stall current of the voltage. I have measured the 100% voltage to be 14.2 volts at the top of the track. The stall current for the gold motor is 1.4 amps and. The round motor is 1.8 amps. Yours may vary slightly from these levels. Clearly these motors with load will exceed the 0.7 amp threshold. Remember, a dirty engine will increase the motor load. Athearn BB engines are prone to truck tower bearing lock and axle gear cracking like but not as bad as the old P2K units. These also increase the train load and thus the operating current.
How should you respond to this message? It must get down to life of the module. At 2 amps, the life is zero, it fails. Below 0.7 the life is indefinite. Not infinite, but generally long enough to be adequate. What is happening to the module life between 0.7 and 2.0 amps? How should you respond? Should there be another warning? Say at 1.4 amps? To keep you from killing the module.
I have recently installed Rail Pro modules on three older units. An Athearn Genesis, a P2K, and an Atlas Kato. During the proof testing of these units, this warning was experienced during part of the test series. These engines were freshly tuned and were excellent performers on DC. How should one respond to this message?
