Fig. 7.53. Check of the traction relay

Check whether there is no break in a chain of the involving winding. Measure by means of an ohmmeter resistance between conclusions "50" and "With" (fig. 7.53).

If resistance strives for infinity, i.e. the chain is opened, then replace the traction relay.

Check whether there is no break in a chain of the holding winding. Measure by means of an ohmmeter resistance between a conclusion "50" and the case of the traction relay. In the absence of conductivity i.e. if resistance strives for infinity, replace knot of the traction relay.
