Recommended Resolver Cable
For the best results, Belden® 9730 (or equivalent) cable is recommended. For
retro-fit applications where Reliance Electric™ resolvers (800123-xxx), wiring
(417900-207CG) or Automax™ systems were used, existing wiring may be used
(assuming it is in good working condition).
