Thank you Bradley for this video. I have some small suggestion on how to simplify your test. if you follow a schematic for an armature you realise that every pole is in contact with each other, all of them. You simply have to check for continuity between one pole and the rest of them, not even all are necessary, the 180 degree is not necessary. Then check for non continuity between one pole (since they are all connected) and the armature. Leads are rather thick and your 1.2 ohm is likely the leads of your measurement devise depending on quality of the leads. Check ohm by putting test leads together. Thanks again!
Realy hope someone can help me. When i test a armature commutator i set multimeter to 20M ohms then 1 wire on shaft and other wire on commutator, then get reading. Is this mean there is a short between ground and commutator? When set it on lower ohms i not get any reading. Just when set it on 20M ohms and 200M ohms i get reading.

What about if someone the coils in armature are shorting, is there any test to try an isolate these shorts?

عمل رائع بطرق علمية جيدة ... كل القيم أعطت 0.13 الا نقطتين أعطت 0.28 هل يعني ان المحرك عاطل ؟
Very good, just 1 question how do u check the main coils in the housing to c if the r grounded or shorted out?
here and here..here and here....I can't see a thing ...show close up...Einstein.
Bad video not clear
