1984 Arrowglass, What do these switches do

[Joey]

First off I am new to boats so please don't laugh to much, I am trying to wire these switches that have been disconnected for some time. 


What is this switch for?

             CHARGE
              2-12 V
 (Actual toggle Switch Here)     
             12-24 V
               RUN

I'm not sure what "Charge 2-12 V", does it mean charge two 12 V batteries that are in not in series? 

And what does 12-24V RUN mean, run with either 12 v or 24 depending how many batteries the boats has.... It just sounds confusing to me.. The boat had no batteries when I got it. Once I understand what the purpose/function I can figure out to hook.


The Other switch is pretty self explanatory  


            Battery
               No. 1
(Actual toggle Switch Here)
               No.2

I assume this is to use either battery 1 or 2 ( but what does this run, the trolling motor?)  

There is a hole next to the switches that looks like a cigarette lighter female plug goes, what would that be used for other than a power source for a some other device. I would have posted a picture here, but I couldn't figure it out. there is the actual trolling motor plug, so thats what i dont know what this cigarette lighter plug is for.
