es127 shuts down

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Pete,

Raymarine product owners may determine the power consumption for most Raymarine products by examining the product's installation guide or operation instructions. Switching the fishfinder ping OFF for both the 50kHz and 200kHz fishfinder channels when underway and operating deeper waters where depth monitoring is not required may reduce power consumption by the MFD. Unlike most marine electronics products, the power consumption of an autopilot is not constant. Sea state, wind conditions, current, vessel speed, and response level configured within the autopilot will all contribute to the amount of power consumed by an autopilot. In this case, you may want to consider hiring an ABYC Certified Marine Electrician to visit the vessel, test the batteries, test the underway charging system, determine the vessel's power needs, determine the time between full charge states, determine underway charging habits, install any required additional battery capacity, and/or install/repair the underway charging system to satisfy the vessel's power consumption needs.
