I have 2 2026 motors that aren't running One is the early style the other the 1951 style. Both are completely apart. i have three armatures that check out #1 reads 1.4 to 1.5 ohms between sections #2 reads 1.8 to 2 #3 reads  1.3 to 1.4 none are shorted to the shaft and all turn free when assembled. The fields read 1.5 and 1.8 ohms. The brush plates and brushes  are good.  When I apply power the armature makes a small move (like it moves  segment) then stops and the motor buzzes if I try to push the armature I feel strong resistance  I have tried switching the parts around between both motors to no avail. I have tried with gears connected and without . What am I missing?

I FIXED IT. I have found in the past that if you write down a problem sometimes the solution presents itself. About a minute after I posted I realized what I was doing wrong. I  had both brushes connected to the transformer and one to the field I had forgotten to ground the field. It ain't easy getting old I find that I sometimes make dumb mistakes like that. Thanks larry & rob for your help.

 Good morning Al, like you I am getting old. As I try to repair my trains I realize my fingers don’t move as well as they used to. Also I have brain farts. However, as my 93-year-old dad used to say, “getting old is much better than the alternative”.  Also, think of our many friends through the years who didn’t get the chance to get old.We all folks have to stick together. Have a Wonderful and happy new!!
