How do check if armature or the Field is bad? Thanks a lots.

Hi Henry,

To have the armature and field tested you will need to take them to a repair shop. The shop will have specialized tools used just for testing armatures and fields. To test the armature windings and the field they use a tool that puts very high voltage but almost no current through the windings. This test will show open shorts in the windings. They will also use a tool that creates a magnetic field around the armature. It tests for a short on the commutator.

I hope this helps with your repair!
