This is funny. I am sitting here writing an article on these transformers for S Gaugian when your question appears.
Your problem is probably either that the roller is not contacting the coil, or that the wire to the roller is broken. As the Duck has pointed out, breaks in this wire often do not show. My guess is that your 19b has a 2 piece roller arm. One piece holds the roller and is anchored to a plate on the transformer core. The second piece is attached to the turret and has two tabs that go over the first piece and control its movement. The lower piece has probably popped out from under the upper piece, and the roller is not contacting the coil windings. To check this, with the transformer unplugged, remove the back plate and look inside the unit with a flashlight. If the strip and bearing assembly has popped out from under the contact lever and stud assembly, you can usually pop it back under without any further disassembly. To check and repair the wire, you have to remove the case from the bottom plate. WARNING ! I hope that you have some experience repairing appliances. You are dealing with something here that is much more powerful than toy train current and can produce fire and shock hazards if not done correctly. Frankly, I wonder if it is a good idea for you to be doing this work. If you are not experienced in this type of repair work it is better done by a professional repairman. For instance, splicing an extension cord into the power cord is a poor idea. if the wire outside the case is damaged, then the wire inside the case is suspect andthe entire cord must be replaced. if you didn''t know this already, you should not be doing this repair. For another instance, before plugging any transformer in, you should test for continuity between the primary and secondary. You didn't mention if you did this test. It is a basic preliminary test for ANY appliance. If you didn't know about this, you should not be doing this repair. To test for continuity touch one tester probe to both prongs of the plug simultaneously, and touch the other probe to every metal part and sufrace on the transformer. If there is an on/.off switch, do this with the switch in both positions. If there is any such continuity, don't even think of using the transformer. I hope I am wrong about the above warning. Please don't get angry -- people need to know this stuff. Tom Jarcho S-Trains list sponsor: http://www.americanflyertrains.com All the Flyer you desire...books and accessories too!
