after a couple of nudges. I took the loco home and removed
the shell. I then disconnected the SoundTraxx external capaci-
tor and connected a KA2 to the capacitor black (power supply
negative) wire and the blue (power supply positive) decoder
connections. I taped the KA2 down on the loco with double
sided tape for a quick check. I let the loco rest on powered
track for a few minutes to assure that the KA2 was charged
up. The second segment of the video shows the loco running
smoothly through the yard ladder. After resting a bit more
to assure a full charge, I shot the third segment of the video
where I removed the running loco from powered track and
set it on plastic running beside the track. It ran about a full
loco length on plastic – no power applied. When the charge
in the KA2 was depleted, the loco stopped gracefully and the
sound quit. Nothing dramatic.
