Some general information about the products this company produced.
Don Thompson recalls that the Chinese factory used automotive paints on their freight cars. All plastic bodies were made out of ABS. Brian Jackson reports that he has had success removing paint from a composite hopper using 91% isopropyl alcohol. He reported that he started seeing results in a few minutes, and large amounts of paint came off after about 30 minutes of soaking.
This covers the eight-pin DC shorting plugs. Don Thompson reports that there were two kinds. They will both work, but one will cause the engine so run in the opposite direction.
For some reason, the factory on three road names of the first run of the SW9 locomotives, wired the motors to the wrong socket. The fix was a DC shorting plugs with the motor lead pins wired correctly. These plugs have a glob of hot-melt on top. You can see red wires in the hot-melt.
It happened again with an entire run of the SW1 locomotives. The factory, again, sent DC shorting plugs to fix this problem. For this run they used "baby-blue" wires.
Note that AC and DCC locomotives were unaffected.
The first photo shows the normal DC shorting plug for engines without a speaker (part #653-X00???).
The second photo shows the version with the red wires for engines without a speaker.
The third photo shows a normal DC shorting plug for engines with a speaker (part #653-X014R4).
Don Thompson mentioned that all of their wheelsets were double insulated. This includes locomotives, freight cars, cabooses, and tenders. Don provided these diagrams (all measurements in millimeters):
