They must be in a handful of tenths of the volt of one another. If not, there might be extreme resistance in the circuit. A lot of vehicles Have a very fusible connection or a big fuse to shield the alternator. These could be burned up by a short or poor use of jumper cables. If there isn't a electric power with the alternator B+ (huge output terminal) then a nasty fusible hyperlink or maxi-fuse is most likely the challenge.
