Ford ES — TESTING OUTPUT BRIDGE DIODES

For the Ford ES.

Browse Ford generators & specs →

Procedure

  1. Connect one ohmmeter lead to each end of diode
  2. Reverse ohmmeter leads and again observe re-
  3. Replace defective diodes with new, identical
  4. Wires 1-2 and 3-4 are wound on thesame iron core.

Specs & torque values

  • printed circuit board. Using an accurate ohmmeter,
  • 1. Connect one ohmmeter lead to each end of diode
  • 2. Reverse ohmmeter leads and again observe re-
  • OHMMETER
  • Using a 6 volt dry cell battery and a 200 ohm
  • nect a DC voltmeter across the 200 ohm resistor.
  • 0.39 ohms and 0.38 to 0.46 ohms respectively at 77" F
  • ohms, between Xl-X2 133 to 163 ohms at 77OF
  • between field leads should be 10.98 to 13.42 ohms at
  • OHMMETER RESISTANCE BETWEEN
  • 10.98 TO 13.42 OHMS
  • Connect ohmmeter between either field lead and
  • exciter stator laminations. Use ohmmeter set at
  • R x 100 scale. An ohmmeter reading of less than
  • OHMMETER
