How do I replace the power cord on a type kw 190 watt lionel train transformer?

hi Sandra.
see if this link helps you out.
How can hook two trains to Lionel kw 195 transformer no accessories Google...

On a postwar LIONEL ZW TRANSFORMER, Yes the red light will come on if a short is present with the throttle on. As soon as the throttle lever is in the off position the red light will go off. Shortly followed by the automatic circuit breaker clicking, as it cools and resets. The short on the track may still be present but with the lever in the off position the red light will stay off. There are several variations of the ZW 275 Watt transformer, early and late "type R" models. Both work the same but are wired slightly different the early ZW uses two 6 volt bulbs and the "Type R" uses two 18 volt bulbs. Internally if there is a resister connected to the base of the red light it will use the 6 volt bulbs.

No power to the transformer or to the track?
If not to the track, make sure you have the correct wire connections made from the transformer to track.
If no power to the transformer from the wall plug,
sounds like the cord needs replacement.

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

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.

New wire and plugs are available at chuckstrains.com , they can also tell you how to get into it

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.

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.
