**Spur44**Hi everyone! New to the group here and looking for a little information, mostly on the GE -7 line. Surfing through some old threads, I saw where the GTA11 alternator was used on the B23-7, B30-7 and early B36-7s. Then around '84 or '85 they received the GTA24. One of the big orders I can think of that would have gotten the GTA24 would have been the Seaboard System B36s that came along in the mid 80s.

Anyway I read that the GTA11 made traction motor transition and here lies my question. At what speeds were forward and backward transition made for the GTA11, specifically for the B30, B23 and early B36s.

Since the GTA11 was a carry over from the old U boat series, did the -7s and U boats have the exact same transition speeds?

With the GTA24 being a transition alternator, at what speeds did it make transition as well?

Thanks in advance! Any help would be greatly appreciated!
