I basically think to prevent frying your trolling motor. I just found out last week that my "OFF" switch doesn't work on mine; I was moving the pedal up to the front deck, the switch was positioned on off, but the blade spun when my hand hit the tab. I checked it out, and sure enough, the OFF switch is gone; I pretty much have to unplug mine everytime now. Perhaps someone knows what you can do as far as your system goes.

I also used to disconnect the wires each time, then I took the chance and left them on...No Problem!

I make sure the motor is turned off, and just clamp the charger right on the battery. So far so good...

You should only have to disconnect the trolloing motor if it is a model with the infinite speed. I charged my motors without this feature for years without a problem.

If the trolling motor has electronic controls it could be to protect the controls from overvoltage (voltage above manufacturers recommended)  or voltage spikes generated from connecting or disconnecting the charger leads w/charger power on .

For most 12V batteries standard charging voltages are 13.7V float ( 2.28V/cell) and 14.4V equalize (2.4V/cell). However, some cheaper chargers can produce voltages in excess of these. I would suspect the manufacturer is worried about protecting the trolling motor electronics.
