Motors don't turn over if they: 1) have a dead battery, 2) bad, corroded, or loose battery cable connections 3) a bad starter, 4) a bad solenoid, 5) a bad ignition switch, 6) bad wiring between the control box and engine to name just a few things. <br />Never run your trolling motor from your starting battery (unless you like to pull start your engine). Your engine has a very small capacity charging system and it is not capable of charging a dead battery on a 10 or 20 minute run back to the dock. You would have to run wide open for hours to recharge the battery. It does however maintain the starting battery provided you run your accessories off a separate deep cycle battery. The deep cycle must be recharged using a portable charger or single bank on-board chargers are available that you plug into at the dock. When you get the engine running, using a voltmeter, measure the voltage at the starting battery with the engine running at 1500 2000 rpm (pretty fast idle if you don't have a tach). Voltage should be 13.5 or so if the system is charging. If its 12.6 or less, its not charging.
