dragginup, I have a HB 797C2 in the bow. Lowrance LXX-28C at the drivers seat. Been out on the lake about 8 times with the HB so far since I put it on the cat. There has been times I pulled up the trolling motor, left the unit on, buzzed acoss the lake on the big motor, when setting the trolling motor back down I have noticed a “pop up” on the HB screen saying “low voltage”. I always have pushed exit, it goes away and no issues. This has happened 3 or 4 times??? I thought it to be from cranking the big motor? My batteries are serviced and are working great. Could this be normal, or do I also have a connection issue or maybe I should be turning the HB off?? Xducer is on the trolling motor. Or maybe, do what I have been doing, just fish? Next time I will check the actual voltage on the HB and let you know what I see.Last edited by basscatsmeow on October 1st, 2008, 2:23 am, edited 2 times in total.
