No longer have manual for Lionel KW 190 Watt 2 Train Transformer. I have wired the hookup using A to 1 and C to 2 to the track conector from memory. Right or wrong?

Ground terminal. Electro help

Have you cleaned your wheels & roller pickups?

It depends upon how much you run your trains. Run your finger or clean cloth on the rail. If you see a dark mark your tracks need cleaning. You can also run another set of wires from the transformer to the spot on the track furthest from the transformer. You can even run a third or fourth equally spaced apart if you have large loops and long and heavy trains.

There is bad contact in the track connections. You can sand the track connection sites. Another method is to run another power wire to the other end of the track where the train slows down. Even better is 3 or 4 evenly spaced power wires from the transformer to the track.

It would depend on what engine you're trying to run. The 40 watt transformer's circuit breaker will trip off if you put too large of an electrical load on it. If the engine light stays on while it sputters, the track or the engine's motor and electrical pick-ups may need cleaning. Older engines that haven't been run for a while can get stiff. Your engine may need some lubrication.

The Green light on, But flashing and the train don't move

It sounds as though you may have two defective transformers. Lionel has reported problems with some of their smaller transformers. I would have the transformers and the engines checked by a Lionel service station or contact their customer service department for help.

just unplug the transformer from the grey box (the one with the green light and red light) and check the voltage. if it doesn't read anything, try unplugging the transformer from the outlet and plugging it back in again. if you get a reading, replug the transformer to the grey box and check the voltage of the silver screws (where you put the + and - wires from the track to) and try using the train again

The Lionel postwar 190watt transformer is an excellent power supply for trains. If one or more of the binding posts are loose ("U,A,B,C,D" Terminals") you will need to replace the binding post, use a T-159 replacement Binding Post. The original posts are soldered and crimped on.
The T-159 replacement binding post is bolted on. UNPLUG THE TRANSFORMER Carefully pull/pry up the handles and remove them remove the 4 Philips screws on the top, lift off the case top, the binding posts stay with the body of the KW.
Remove the loose bindings post one at a time as needed. Be sure to get any wire reattached. Reverse the procedure to reassemble.
