Put the boat in today and immediately notice the TM didn’t seem like it was fully charged even though they stay on the charger. The lock would hold me in place fine. I would put it on Max power and it would be sluggish. However, when I took it off of lock it had full power. I would keep the button pressed for a while then the battery light would turn red and it would stop. Press it again and it and it Would be sluggish. Every single time I put the lock on it would hold fine and once I got off of lock it would work for a little while. I also noticed that after it would cut off and the battery turned red he gps would not connect for a while and it would not lock. After about 45 seconds or so it would acquire a signal and the lock would work. We just checked the batteries and they appear to be good. Any ideas? Thanks.
