Check of a winding of excitement of a rotor


We remove the brush holder (see Replacement of brushes of the generator).

Through a window in a cover of the generator we check a rotor for short circuit on the case, having connected one conclusion of an ohmmeter to a krylchatka of the fan of the generator, and another – to a contact ring of a winding of excitement.

Also we check lack of break in an excitement winding, having connected device conclusions to contact rings.
