Lionel ZW Transformer Issue

Steven writes:

“Hello, I just purchased a ZW transformer over Christmas and got it running. It worked great on all 4 throttles. Then there was a derailment and now D-U doesn’t work but A-U, B-U & C-U still work fine. I took off the cover and everything looks in good shape however I did smell a slight odor; not sure that is normal or associated with the short (train derailment). I measured the resistance on A-U and I get 236 ohms while I get OL on B-U, C-U and D-U however D-U is the only throttle that doesn’t work. Any help you could provide would be greatly appreciated.”

    You may want to consider buying Greenberg repair manual which covers post war lionel trains and transformers. See if there are any youtube videos on the ZW transformer.
