- TL;DR Summary
- Why does switch have normal open and normal closed contacts
I have my field windings on the bench and it has a heavy and light wire wound in pareral there are three wires off the field windings . It looks like to me after testing switch with ohm metter positive turns on motor but when switch is in on position green wire off switch is not connected to smaller wire in field windings , but when switch is off there is connection from ground thru field then to ground. I can't figure out what is the smaller winding in the field used for? The bearing went out in motor and windings got hot wires are still good looking but the small and larger field windings are shorted together but not to ground. When I get my bearing I will run motor to see if it works and run with large field winding connected to AC and leave small wire in field disconnected. I do not have ringer so can't test field.
