Procedure

  1. 14. Perform tests as follows:
  2. 2. Connect ohmmeter leads between F1+ and rotor
  3. 3. If meter registers, rotor is grounded.
  4. 4. Replace grounded rotor with new, identical part.
  5. 1. Remove rotor: leads F1+ and F2- from rotating
  6. 2. Using ohmmeter, check resistance between F1
  7. 3. Replace defective rotor with new, identical part if

Specs & torque values

  • Resistance should be 0.5 to 0.6 ohms at 68" F (20" C).
  • Connect leads of ohmmeter between each CR lead
  • ohmmeter. An ohmmeter reading less than infinity
