make sure you hooked them up correctly. you need to series the batteries. to do that you will need to hook positive on one battery to negative on the other. then hook your load to the open positive and negative terminals.

Not necessarily, some trolling motors have the jumper in the plug and you run four wires to the receptacle.


i have a jumper. i've had 24v systems before and know what to look/chk for on trolling motor. all other stuff: horn, bilge, aerators, washdown pump are now dead. all i did was disconnect, replace, reconnect. i even labeled MOST of the connections as to which battery they connected to. i ran out of daylight so i quit and opened a beer and came to the OB.
im open for discussion

I would unhook everything and start from scratch. Check each battery without the jumper. Install the jumper, test the voltage. If voltage is good, add one device, check voltage, add the next...
Of course checking all fuses goes without saying.

First thing I would do is move all that stuff to the crank. I've never heard of running accc off the 24 volt part. Then, when you have nothing but TM on there, you may have easier trouble shooting.
