Was out on a lake last week and put the trolling motor on constant for a while and my bow-mount 320C just died. Was dead for the rest of the day and magically turned back on the next morning as the batteries charged (didn't check it when I got home and began charging). Has this happened to anyone? Does someone have a suggestion to prevent this from happening in the future (other than running the TM on constant for prolonged periods of time)?

Also, temp gauge isn't working properly. Someone else experience this? Should I send it back for a new one (bought this past winter either 12/08 or 1/09)?

Is the unit powered by the trolling motor batteries?

I would highly suggest changing that so your sonar unit is running off your starting battery and having your trolling motor batteries just for your trolling motor. This is where your problem is more than likely. The other possibility is that if you have a inline fuse on the wiring, there could be a loose connection. My guess though is there is interference with the trolling motor and having it hooked to those batteries. This is a very common but fixable problem. Leaving it connected to those batteries could risk the life of your unit.
