Raymarine A65 Shuts off Whenever it is in the mood
I have the unit hardwired to one of the batterys, It doesn't matter if I run on batt 1 or 2 or all. It was sent in to Raymarine because the unit would not boot up under warranty. Now out of warranty and my first full week of use, it just shuts off. voltage is always 13.1 to 13.3. I have the upgrade and had to buy the new antenna to get waas capable again, and was still under warranty. Not happy with unit and bought a garmin handheld for backup Help if you can, will sell if you want it.
Re: Raymarine A65 Shuts off Whenever it is in the mood
My A65 was constantly shutting itself off. I did the reset and the unit is working just like it should now and I have had no more problems.
Go to Setup, System Setup, then Settings Reset and press Enter. This returns all settings back to their original factory values. It should not reset your waypoints or route lists. Raymarinerecommends you backup your waypoints on a separate Compact-Flash card but I didn't do that as I wrote down my all my coordinates. Hey I'm a fisherman all I care about are my fishing spots.
I'm not sure what setting it was that I changed that caused the adverse affect of the unit shutting itself off but resetting the unit did the trick. I was more careful about adjusting the display settings to my liking by doing them one at a time and waiting to see if the problem returned. It has not so far, knock on wood, and the unit is working the flawlessly now.

Check cable connections, reseat all at both ends(so say the book) Now disconnect all cables, CAREFULLY open the housing, visually check internally.Perform as a surgeon would do, reseat all connections(flex cable,wiring,IC's,& the liquid crystal LCD display) clean as necessary with electronic spray cleaner & red eraser. Reassemble. Reconnect. Good Luck.(definition of 'reseat'- unplug or move unit in socket to reconnect the components leads)
Likely your DSM25 (that little box that connects the transducer to the display) will need to be rebuilt. The red LED is saying that there is an internal fault with the unit. You would need to send the unit in for repair through Raymarine (as there really is not anyone else who can do it), and they would have to replace the main circuit card in the box. I believe that they are charging either $150 or $175 to repair those now... but likely the only way you will get that one to work again.
This is a very common marine electronics problem. You probably only have one battery that runs the engine and the electronics don't you? The engine when started creates a very significant draw of power when it's cranked. If the battery is old more so than ever. When this power draw happens, your machine brown's out. The electronics try their hardest to keep the voltage up but they can't because they're being starved. This can cause electronics to have memory issues, get garbled up and not perform correctly upon startup. Either add a house bank that is separate from your start battery or turn your unit on after the engine has started.
Probably a bad printed circuit board, just had to send mine in to have it repaired. When I hit the power button, I did hear a beep, but then nothing displayed. Mine was still under warrenty, so don't know the repair cost if yours is not.
My Raymarine A65 was so bad in daylight I could not read the screen. Used Never Dull polish from ACE hardware, similar to Brasso, and it took every scratch and cloudy mark off the screen. The can documentation includes glass as one of the items it?s safe to use on. Looks new again, Good Luck, Paul
If you have a loose RS12 try moving it around the deck and see if it make a diffrence.There might be something knocking it out.
If it is doing a cold start it cold take up to 10 min to get a fix. Once it has a fix it will aquire the next time much quicker.RS12's are mostly rock solid and get great fixes.
Also set the time up on the A65 to what you are at ,IE, universal time minus 5 if you are on the east coast of the US.Time set up is under the units menu. Hope this helps
Was the engine running when it shut off? How was the voltage at the time it failed? The A65 will shut down if the voltage drops below 11.2 volts.
Another common cause would be corrosion on the plug where it plugs into the back of the display, or the terminal connectors that attach it to the boat's power supply.
It could also be a bad crimp on the terminal connectors. Make sure connectors are the right size for the wire and that they are marine grade, such as Ancor brand connectors. I also recommend heat shrink style connectors,
I have not heard of any software issues for that model so I am betting it's a wiring issue. However, there is an update available from Raymarine. There were changes made to the WAAS satellites and the update helps it recognize the new satellites. You can download it for free from Raymarine. Copy it onto a blank CF card and plug it into the card slot on your GPS. When you turn the unit on it will prompt you on how to proceed with the update. It will fix any known software gliches at the same time.
I hope this answer helps. Please reply if you have any questions about my response.
When the engine starts, there is a voltage drop as the starters crank, followed by a power surge as the alternators kick in and the voltage comes back up.
Ferrites are only there to prevent RF (Radio Wave) interference from other onboard devices.
You should either:
-add an isolated battery to the boat to service only your electronics. That way it is unaffected by the starters.
-There are several devices on the market like Newmar Power's "Start-Gurad" that automatically switch electronics to backup power during engine start. They work great and the electronics don't skip a beat.
