here's the deal i just bought a new 12/24 trolling motor to replace my 12 volt model. heres the problem i have no idea how to connect my 2 deepcycle batteries to support a 12/24. i have 2 red positive cables and 1 black negative cable comming from trolling motor plug at the bow. the plug says it's a 12/24 plug so i guess its ok. theres also on free space (electrode?) on back of the plug i assume to connect another black ground. i've been told i have to connect them in series, then i was told to connect a jumper from one batt neg to one batt positive i'm completely lost HELP
