The Full Load test was the first thing I did with both engines, but the SW1500 required about 30+% throttle to get it to move, whereas the RS2 only required about 6%. I guess I'm going to have to check for binding in the drive train. It is a brand new engine though, as is the RS2, so maybe it just needs to be run in for a while. I guess I'll build a loop of track and turn it loose and see if it lessons the load.
As to the track, it was just 5 sections of flex track with joiners and clip cords to the power supply. But the thing that puzzles me is that the voltage didn't drop off more than .04V from the power supply to the end of the track. And it didn't matter whether I was running one engine or MU'd 2 of them.
BTW, both engines are current production models, not the old BB.
One other question, the IB says to use 16 ga wire for a bus. I'm going to have a large layout and will probably need 4 power supplies. 16 ga seems pretty light after using 12 ga for years at the club. Is there any problem with using 12 or 14 ga. wire for the bus line? Or is the current demand that much lower than what Digitrax requires?
