Its that time of year to venture into the unknown.  I am in the process of restoring several Lionel 2037 and Lionel 2026 engines.  The first two projects, both Lionel 2037 have gone smoothly,  I converted the smoke units to liquid.  man do they smoke.  The next engine is the Lionel 2026, the early style with the more complex looking valve gear assembly.  While the e-units worked perfectly on the first two engine, this one does not.  It initally worked when I tested it after I took it off the motor (putting one clip on the e unit terminal and then touching frame with the other clip).  After a few tries, it stopped working, so I have disassembled the e unit, and looking at everything. 

 

My question, is there a preferred way to test the coil to see if it is still good?  It may by just a wire broke off that connected to the frame or terminal.

 

Thanks in advance for your help.

Rail,  thanks.  I think its probably broken wires.  THey are really brittle.  I have taken apart the e-unit,  I recall testing the coil on a crossing gate a while back, I think I just put the plunger in part way and then added some power to the coil and if the plunger moves, then the coil is good.  I will try that later to night and see if that works.

 

 

Other than broken wires, coils rarely, if ever go bad. Check the contacts, replacing them if they are worn through, and replace the drum if it is warped, burned, or the pivots on the end are worn. Reassemble the e-unit, making sure the contact fingers touch the drum properly and with sufficient pressure. Add and remove power to the coil wire and the frame, and the e-unit should cycle.
