The green light on the right side is a power light, and is on whenever there is AC power connected to the cord. The red light on the left is a short circuit indicator, and comes on when the center rail is grounded to the outside rail by any number of reasons, usually a derailed car, or wiring problem. Check photos on ebay to see what the red and green lenses look like of they are missing. There is a 40-50 year old circuit breaker that should pop during a short circuit, if the breaker is still working properly. If you want to test it, just lay a screwdriver between the center and outside rails until the left light comes on, but don't let it go too long, it could get hot and cause a fire. If it does not pop, you need to get it serviced.

If you have a volt meter you can check the rails for power, Check the transformer wiring to the first rail connection and then along the rails for loss loose connection(s). If you have power to the rails it is an issue with the Engine, Check any brush or rail riders (connections) for a bent or broken tab. If for a temp fix in a broken connection tab or brush you can use Tin foil. Hope this helps.

first you need to test the actual transformer's input then the outputs on primary and secondary winding. Be careful because you can get a schok. If you do not know what you are doing with electricity and don't understand how to test transformers then you should consult an electronic service center to help with this procedure.
Here is a guide to test transformers. http://www.infobarrel.com/How_to_Test_DC_Voltage_Using_a_Multimeter
Since this is a train control there is a potentiometer in it (variable resistor) you will want to check that as well.
In the end the best and cheapest route is look for a replacement one.

See link below to PDF file with instructions to your transformer. It looks like you are correct with regards to the wiring with what I can see in the manual.
Hope this helps and good luck
