Weird thing yesterday: My new last year Raymarine A57D on Whaler Outrage 17 shut down several times, no apparent reason. Possible correlation was when starting engine and maybe (now that I think about it) when hitting trim switch but not confirmed. The electrical connections should be good (Tom G did them) and battery should be fine (but who knows?), Volt meter running steady 13 VDC - definitely in the green - all day long. Not sure where to begin troubleshooting. Will call Ray on this one and check connectors. I plan to take her out today. Conditions were 0-1 at beginning of the day on Lake Mich and then at least 4-5s, reports said 6s plus big yacht wakes. Boat was awesome in those conditions but we could have shook something loose. I appreciate any ideas. Best |

Speaking from personal experience, the newer RAYMARINE A-series devices are quite sensitive to low input voltage and will typically react when the battery to which they are connected is also used for engine starting and has its voltage sag during cranking. The solution is to reconfigure the vessel wiring to have an isolated HOUSE battery that is used for powering the electronics and will not be affected during engine cranking. |

Thanks Jim - on my list of possibilities. I put the battery on charger anyway and planning to go out this afternoon - Hurry over!!! Lake Mich is 0-1 ft and water temp report is 75 degrees F. I need to figure out how to wire in two batteries. Thanks!! |

Pete, How old is that battery? If/when you change to a dual battery system it may be a good time for a pair of fresh batteries. Butch |

Pete--I direct you to my review of the RAYMARINE A57D at http://continuouswave.com/ubb/Forum6/HTML/002467.html wherein I noted the tendency for the device to reboot every time I cranked the engine. |

Yup, you are correct Jim, I recall that now and the statements in the manual. We had a long Lake Michigan/beach day, 0-1s and 75 degree water. I did charge the battery and suspect it is old. One shut down and easy reboot but will go through the fault tree soon. Thanks, I'll keep you posted. |
