I have a minnkota 24v troller with autopilot. I seem to have trouble getting it to work all the time. There is also a large delay (5 seconds)and I have to have it set to a higher speed (5+) to work with the controller for the prop to turn. Once it starts I can turn it down a little. Is this normal. The autopilot won't work at all. It just sits and twists back and forth, but the prop won't turn. Is this a possible bad battery connection? When I bought it the previous owner had just stripped the wire and sandwiched it between two washers on the battery. I have added ends (crimped), but I am wondering if I go thru the whole thing and solder everything if that will help. Or does it sound like a controller problem. I appreciate any help you can provide.
