Chris, I have never heard of anyone ever being told that the tsunami can handle 2 amps, the scoop I got from them was that it was ok for just over 1 amp... Ed Sauers

The large lead weight "seems to be doing a good job" of heat dissipation. But, admitted the unit does not have much running time. It seems best to raise the decoder up a bit in the crevice so the heat dissipates from all sides as well. However the large lower tech motor does worry me. Soundtraxx has stated to me that the max amperage is 2 "and a scootch". I did two things to give myself some leeway. First I decreased the rear weight to balance with the weight on the front drivers (or better said in the front boiler and mechanism added together.) The excessive rear weight as delivered was in my view putting all the weight on the rear, canceling the front, and causing excessive motor draw and coupling wear. Secondly I did not wire the tender light to the decoder as these were 12-14 volt 50-60 milliamp bulbs as delivered. The front light was replaced with a 1.5 volt 15 milliamp bulb. I have a DCC ammeter on order and will report amperage draw later. Based on DC wiring the highest I reached was 0.6 amps.
