I have a Crown 3020-30 and the The battery gauge has stop working. I have power the the Curtis control but I I'm only getting 3.9 volts on the key on line. I am really hoping this is a simple fix. I have installed an new Curtis and gauge we had am extra set but still have the same issue. I wish I had a wire diagram for the lift I do not. has anyone ever seen this issue before be great if someone could point me in the right direction. The lift also will cut out as soon as go in forward or reverse not sure if the 2 issue are from a common source but I figure if I can tackle on issue maybe I will resolve both thanks. Chase
