I'm wondering, since the B-18s were outfitted with Radar for ASW, if the
electrical systems were upgraded to handle the extra loads?  The radar
probably operated on 80 or 115VAC at 400 or 800 cycles, but would the
DC system have to have been upgraded to 28V as well?

The reference I have says that 122 (out of a total of about 300)
B-18s were equipped with "ASV radar and MK IV MAD" but I'd guess ASV 
refers to the acronym rather than an equipment type.
