Need help testing PW e-units

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.

Dave
