I have a curious issue. I have a 180W Powerhouse connected to the TMCC Direct Lockon, all works well. However, if I try to run my Lionel 3927 Track Cleaning Car, the TMCC Lockon shuts down almost immediately. Without the lockon, all is well, obviously with less protection.
I've put some 1uF caps across the brushes to chassis ground like is done for TMCC AC locomotives, I thought that would damp any electrical noise, obviously not sufficient. One other change, I have a series diode in the track cleaning car to cut down the voltage the motor runs on, I'm wondering if that is the source of the issue. The motor works pretty hard at 18 volts, so I want to lower the voltage a bit.
