About three weeks ago, I was out on the lake and my trolling motor stop functioning. At first the anchor mode stop working, then I lost all power from the foot control to the head unit on the trolling motor. Call Lowrance and they suggested doing a factory reset. I did, and things start working for about 20 minutes and then stopped. Got the boat back home and everything started to work again. Went out the next day, and the issue repeated. Lowrance Tech stated to bring into a service center. It sat at the service center for three weeks and they stated they could not find and issue. So, put it back on the boat the next day and went out on the lake the Trolling motor lost control again to the head unit, no blue arrow, no reaction from the foot pedal, however the foot pedal displayed power. Call Lowrance again and they sent me to a different service center. It's been there for the past two week. I have hard wired the motor, removed the plugin receptacle, load check batteries, change to a 60 amp breaker, still nothing. Lowrance rep suggested that the head unit control board was intermittently losing power. The Ghost is the 2020 model. Has anyone else had this issue?
