Set the ohmmeter to a range that will conveniently read up to 50 Ω.
4.
5. Remove the six phase generator connector from the lower PCA, refer to Diagram 5.1.
6. With an ohmmeter, read between terminals 1 & 2, terminals 1 & 3, terminals 1 & 5, terminals
1 & 6, and terminals 1 & 7 on the six phase generator connector (J1). Each of the readings
should be between 36 Ω and 40 Ω.
7. If any of the readings are significantly high or significantly low, remove the intermediate
cable from the generator and perform the same measurements as in step 4 on the
generator connector. If the reading are now correct check and or replace the intermediate
cable refer to Diagram 5.1. If the readings are still incorrect, remove the six phase
generator.
8. Replace the generator per Procedure 7.10. Reconnect the intermediate cable removed in
step 5 to the replacement generator and the lower PCA.
9. Reconnect the red battery lead to terminal M6 of the lower PCA.
10. Set the black plastic shield in its mounting position and fasten it with the screws removed in
