Hi, We put our boat in for first run after winterization this week. The service shop hit the battery off switch put unhooked the batteries. When i started the boat the warning buzzer stayed on instead of cutting off...the gauges were good, no lights on dash and it ran great all day...does anyone know why the buzzer would be on and how to cut it off. i feel like it had something to do with the ground or batteries being disconnected. Thanks for the help.
