I am currently in the the process of trading a firearm for a garden tractor the guy I am trading with wants to throw in a motor guide 12/24 volt trolling motor that is in good shape for its age.The problem is I don't even know what 12/24 volt is,how would it be different from my 12 volt? Can it run on 12 or 24 volt? what does this mean as far as batteries are are concerned. I currently use a starting battery charged by the o/b and an independent deep cycle ,charged with a charger for the 12 volt trolling motor? Would I need to add a battery and or a switch? would this be wired in series or parallel ?Are there draw backs to 12/24 volts? Is there any thing else I should know Even if I don't go with this, this is still info I would like to have for future reference Thanks in advance
