2018 Yamaha 242 Limited S E Codes Coming Up on Screen

[Kernsy]

I put my batteries on my NOCO Genius 2 trickle charger and one bank has a flashing green light.

I think one of my Interstate batteries has bitten the dust. It is reading no voltage. It is my house battery. My start battery is showing 12.2 volts on my screen. I am installing new batteries tonight.

I have been reading up on the forum & it seems to suggest a bad battery will throw codes.

My codes are Low voltage, GPS Error, Keypad Error.

When I turn on the switches, my blower comes on and screen lights up with error codes but I cannot start it. Throttles are in neutral. Clean out plugs in and hatch down.

Is there anything else I should be looking at?

Thanks

Hi Kernsy -

You may need to look at modifying the automatic transfer switch/DVSR as detailed in this thread:
https://jetboaters.net/threads/battery-switch-and-dvsr.36664/

If you don't, you risk your dual-bank charger actually directly connecting through the DVSR and that will kill batteries as well as the charger.

This thread also discusses the DVSR and dual-bank battery charging

That is the little black wire that is connected on the negative terminal. I need to take that off? Right? I did this on my 2017 242 Limited S every time before I hooked up my NOCO Genius 2 bank charger. I forgot all about doing that.

Am I on the right path?

That's the one! There are some folks that have come up with creative ways of automatically disconnecting that (or just putting a switch inline) but as long as you effectively disconnect it, you're on the right track.

This post in particular covers a lot of great stuff:

Thanks Quad. I don't know how old these Interstate batteries are on my boat. There is no stickers marked out on the top show that show. I told my wife and I just going to install new Interstate 24M-XHD 800 CCA 1000 MCA. These are the ones on it now. I talked to Stokleys Marine this morn too and he said a bad battery is the #1 cause of throwing codes on the screen. He said to replace both with new so I have peace of mind.

My wife and I have no paperwork on the age of these batteries so I am just going to replace both.

Thanks Quad for the help. I really appreciate. I still have so much to learn about my boat. I am getting there.

I just drilled a hole in the battery handle and put a toggle switch in it. Turn it on with the batteries and then off with them.

On my 2017 242 Limited S I just disconnected it every time. Then reconnected it before heading to the lake. More time consuming but I did not mind. I loved being on that boat every second I could.
Thanks for the advice.

If you follow the thread posted in the post that @Quad is referencing you have no need for a switch that you can forget. Its easy to access a ignition feed to activate the dsvr. Its a no brainer in my book

Update:
I installed 2 brand new Interstate batteries tonight and my engines fired right up. One of my batteries was completely dead. I mean NOTHING.

I then flushed each motor and I got an Error Code: Keypad Error on touchscreen.

I checked my volts when each engine was running and they were indicating 12.4 to 12.5. I was just idling. My keypad joystick did not operate at all. Nothing worked on it. My touchscreen worked. Is there something I must do to get the keypad (joystick) to work?

I have both batteries on my NOCO Genius 2 trickle charger tonight. I read up on the forum this lower voltage could throw an Error Code.

Also, I noticed my port shift gate was a little higher above the jet nozzle than the starboard side. It was not much but I did notice it.

Any thoughts or ideas would greatly be appreciated.

12.5 is low while running even at idle. Should be 13.5 or higher.
I dont know why one of your new batteries were dead. Did you charge them fully before install?
My batteries read 14+ while idling and 12.8+ at rest

It was one of my old batteries in it that was dead. I put my new batteries in and they will charge all night on the trickle charger.
