Last time I used the terrova, when i deployed it and pressed buttons on the remote, the remote stayed blank, and I could not get it to come on. I finally pushed a button on the foot pedal (mine stays connected), it was the right left turn arrow, which moved the head a little, and then tried the remote, and it turned on. The low battery indicator led light was not on to indicate a low battery. What could have caused this? This morning, I remembered something, and i turned on the remote and the backlight.....the backlight went out and the low battery indicator lit up, but the low battery signal does not come on while operating the trolling motor without a backlight. Could the remote battery be low enough to cause the remote to not come on, even though the low battery indicator does not stay on? Thanks.
