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.
connect all the positive posts in series and all negative posts in a series
will a 200 series bullbar fit on a 100 series
Connect Positive on A to Negative in B then Positive from B to whatever Positive on A had been connected to.
where are the headlight relays on a 75 series landcruiser
When a dry cell is connected in a series, the flow of electrons moves from the negative terminal to the positive terminal. Electrons are negatively charged particles and are attracted to the positive terminal while repelled by the negative terminal. This movement creates an electric current that flows through the circuit.
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.

port should be under dash
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.
