Positive to positive and negative to negative should measure 0 that should NOT make a circuit. You also stated that when plugged in or engine running you measure 12 at the 1 pos and 1 neg, this says everything outside the battery compartment works. One possibility is one of the 6 volt batteries is wired in backwards???
If the 2 6 volts are wired in series, and he is measuring positive on the first 6 volt battery to positive on the second 6 volt battery, it is the same as measuring positive to negative on one 6 volt battery and should read approximately 6 volts.
