was on spot-lock yesterday and noticed boat was drifting. locked down and it happened again. thought my remote battery was bad. then using the continuous-mode the power light on foot control went out. powered up and it happened again. maybe not the remote? got home and checked voltage. one battery 12+ volts and the other 8 volts. charging... anyone experience this? guess i'll pull the battery and have it checked. I've had this tm for over 2 years and this is a first. had to leave'm biting!
