At least its running good,Sounds like its the sender.Disconect the wire and see what the guage, then ground the wire and see what the guage does,it should swing from one side to the other,if it does not swing and you know the wire is good the guage is no good,if it does swing the sender is no good, good luck. Also I was out at crab ledge an got lucky,Sunday 13,no birds,whale,but got a
51" tuna app.75lbs and a short one.Photo soon.going to try the bay next.
