A high speed aircraft generator may utilize a prefabricated crossover subassembly to interconnect field coils. The crossover may include two attachment leads interconnected with a section of braided wire. The braided wire may remain free of brazing filler metal after the crossover subassembly is brazed into position between field coils of the generator. Consequently, the crossover may remain flexible and may have reduced susceptibility to fatigue failure that may otherwise result from circumferential relative displacement of the field coils from one another during changes of rotational speed of the field coils.
