POSITIVE, just found out the hard way!
yes
The voltage adds if you connect in series (positive to negative). It stays the same if in parallel (Positive to Positive and Negative to Negative).
no,they are quite different.
In parallel connection all the positive terminals are connected with positive of the source and all the negative terminals are connected to negative of the source. Whereas in series connection one positive terminal is connected to the negative of another, like wise it goes on and finally the positive end is connected to the negative of the source.
connect all the positive posts in series and all negative posts in a series
Connect Positive on A to Negative in B then Positive from B to whatever Positive on A had been connected to.

2 batteries are wired in series then these 2 are wired in parallel with the other 2 which should also be wired in series. series is positive to negative and or negative to positive. parallel is pos. to pos. and neg. to neg.

In a negative ground system, hook the vehicle ground (frame) to the negative of the first battery, positive of that battery to negative of second battery and the positive of the second battery back to vehicle positive. ( starter or starter solenoid) If you are hooking 2 12 volt batteries in series you will have 24 volts.
