Xfmr problem: Can you substitute a load resistor, 50 to 100 ohm, across the transformer output. This would eliminate the tracks shorts, and engine problem. You can also build a cheap test transformer. Buy a light dimmer switch from W-M for $4. Buy a 12volt-2 amp transformer from Radio shack. The dimmer is hooked to one leg of the 120 volt input. The 12 volt output is hooked to the tracks. With no reverse, you would kick it on twice to keep going forward. I just recently cheked out a Lionel on my homemade transformer, and it works. Hope you have a muiltimeter , great for checking things out

transformers

It should be OK to run with a larger output transformer. "0" scale uses a variable voltage Alternating Current transformer. The engine will draw only what it needs to run. The larger transformer should run all. In "HO" scale it is caled a power pack because the AC must be converted to Direct Current inside the power pack. Again, the small ones will not run the large engines. I tried to run a heavy brass engine with a 2 amp power pack. It didn't start. I needed a 4 amp power pack to run this brass engine. The 4 amp power pack will easily run the small engines in my case.

Transformers

Spider 63: Did you check out the transformer with a voltmeter or 12 volt car light bulb prior to hooking it up. Possible a short in the tracks or engine.

When you get it back, plug in power, run up the rheostat to max. Listen for hum and wait for smell. If negative, run down rheostat, connect to track with no engine. Run up rheostat again. If negative again, run down rheostat, install engine, run up rheostat and repeat test. I have just checked out about six Loinel transformers about 50 to 60 years old. would you believe they still work.

Glad you had good lucj with the local shop, way to go. Loose wire is called poor contact in the business. I also would br wary on buying over the internet or e-basy. I have just checked out and repaired a dozen power packs and transformers for the head guy at our train club. He will try to sell them on e-bay. If you see the name , Dale Kuckenbecker, as the source you know that I Stan has checked out the units for operartion. I will print out a spec. sheet on the units I worked on, and will give it to the train head guy as well as put it on this forum. Stanley
