Hi folks,

I've got a couple of questions regarding the electrical system of the NG:

1) According to my schematics, the battery switch position has no effect on the battery bus - it is powered whenever TR3 is powered or the battery's voltage is sufficient. Is this correct?

2) Can the electrical load be shared by external power and an IDG? Say you connect external power and then select the left generator. Would this disconnect external power completely or would the left transfer bus be powered by its IDG while the other transfer bus receives its power from the external power?

Thanks!
