Field Coils

Check field coils for ground using a test lamp. Check field coil winding resistance using an ohmmeter. If not within specifications, replace field coils as follows:

Mark location of pole shoes to avoid incorrect installation. Unsolder both winding ends from terminals. Unscrew pole shoe screws and remove pole shoes and windings. Install new windings on pole shoes. Align pole shoes carefully prior to final tightening of pole shoe screws. Solder red marked winding end to D- terminal and blue marked winding end to DF terminal.
