Lionel ZW Transformer

[Bob.M]

I had to replace the old bimetallic circuit breaker in the postwar ZW. It was tripping on very light loads.

The replacement was a Bussman type UCB 15A  Type 1 Auto Reset with ATC footprint. Part no. UCN-15, which I found at the local Autozone car parts store. Mr. Lionelsoni had recommended Type II which resets only if you remove power. The store I went to did not have that model. Type I will cycle on & off until you remove the overload, similar to the way the old bimetallic one did.

• I am looking for information on the ZW transformer. I have an old one that was working fine. Now when I put a motor on the track I get a short light. The breaker dose blow but the light comes on and I get no power.Can anyone tell what might be the problem or tell me where to get an exploded view of the ZW. If not maybe information on rebuilding the transformer.
