3-28. MAGNETIC REVERSER SWITCH
This task covers:
Tool kit SC 4940-97-CL-E12
Dry-cleaning solvent (Item 30, Appendix B)
Sealing compound (Item 8, Appendix B)
Variable dc voltage supply
High voltage is used in the operation of equipment. Do not be misled by the term LOW VOLTAGE.
Potentials as low as 50 volts may cause death.
Remove rings, bracelets, wristwatches, and neck chains before working around the locomotive. Jewelry
can catch on equipment and cause injury, or may short across an electrical circuit and cause severe burns
or electrical shock.
If magnetic reverse switch is suspected of
being defective perform steps 37, 38, and
39 before removal.
Disconnect wires from relay assembly and tag
lockwashers (2), flat washers (3), and magnetic
reverser switch (4).
