Yamaha 2021-2023 Low Fuel Alarm, Reduced Fuel Tank capacity?

[skeeterzx225]

Kevin Shaw said on a recent video that Yamaha has no intention to resolve the existing Fuel Alarm/Resetting Data issues, they hope the eventual next generation of Connext will fix them...not good...

[Mr. GP1800]

If you really don’t want your trip meter to reset you can leave the ski in accessory mode while it’s stopped. To do this you shut off the motor. Wait for the dash to want to go to sleep where it gives the option to shut down or remain in accessory mode. This is how you run the speakers with the motor off. I did this on the first long ride I took so I could gauge the accuracy of the fuel used meter and figure out how far I could push the ski before running out of fuel. The fuel used is dead accurate.

But using the infoI have posted earlier in this thread you can know exactly how much fuel is in the tank at each gauge reading on the dash. If you take a little time and make the effort to really get to know your ski, the stupid fuel gauge and trip meter aren’t that big of a deal. I currently have my warning buzzer unplugged, since it goes off at around 55 miles into a trip. That in itself is stupid because I can go 75 miles on my 2017 GP before the buzzer sounds. I plan to install a switch so I can manually turn off the buzzer any time I want to. I have all of the correct plugs so I can make this a plug and play setup. No wire cutting or splicing required.

So, I checked on my ski, powered off, let screen power down, then just powered on screen without trying to start. My fuel used info was reset.

So, not doing that on the svho, I have someone in my ride group who has the 2022 Ho they don’t get a fuel reset so it’s possibly somehow wired differently.

I have isolated all 12 vdc supplies to the multifunction information center to no avail, all trip information resets to zero, except the hours
Likewise I have connected a second battery to completely isolate the multifunction information center to no avail, all trip information resets to zero, except the hours.

It would appear there is no memory back-up for the trip information, when the multifunction information center is powered down, contarary what I said previously.

Yamaha YMUK customer services are not interested in accepting or resolving this issue in anyway shape or form, my supplying dealer has raised the issue Yamaha UK

As an intrim workaround to the actual fuel level onboard, I have begun adjusting the fuel float arm allowing the fuel guage to read more accurate over the full range disconnecting the buzzer. Paying more attention to the warning lights in the meantime.

As someone has already mentioned on here, Fuel Gauge to Sender Ohm Range Converter Module For Update Gas Tank or New Gauge I have one on order to improve the fuel level scaling.

I posted about this a few weeks ago.

It is possible to create an interposer module that translates the electrical signal from the sender inside the fuel tank such that the dash displays a different ‘level’

t would ‘work’ in the sense that the audible Low Fuel alarm could occur when there is less actual fuel inside the tank.

It would not increase the usable fuel capacity of the factory fuel tank, which is noticeably less than 18.5 US gallons.
Which is apparently less than the usable capacity of the nominally 18.5US gallon fuel tank in models prior to the redesign

Why is this not a simple small electrical relay solution? A small circuit that always adds an additional +4 gallons to the fuel level? Yes that is a danger to normal riders for being stranded on the water. But for all of us not this site, we can factor this into our rides calculation. I once had a Nissan Altima. Those cars had a well known passenger airbag poor wiring solution. The only official solution was to buy another $1300 front seat. Instead I bought a $100 relay that made the car think someone was always sitting in the front seat. Yes the air bag would always deploy if accident occurred. No I never let a child sit up front. Plugged the seat belt in with a teddy bear and passed the state inspection for $100 instead of $1300. I primarily only drove the car by myself to work. Don't see why this fuel alarm cannot be solved with a similar low cost solution.

Just an example, if you leave ski for say lunch, arm it with pin, and on return the dash is playing up, how do you enter the pin

Engine no-start while dockside may be a hassle but it is not a risk to safety, compared to a stranding out on the water somewhere far from shore or help

I have no hands-on knowledge for how the Touch screen models will behave but I would hope the engine start and run functionality would continue even with a failed dash. Along those lines, I think the dash can be unplugged from the wire harness and the engine will still work. My own Yamaha GP1800 are pre-Touch screen and work just fine with the dash disconnected

Why is that a concern?
Is there something making you feel that a dash failure is likely?

The engine should still start and run even if the dash unit failed, no?

I'm not sure whether the engine will start or not with the unit inoperable. If it does, then great, I can still ride back to safety. With the newer WaveRunners, more of the power management is controlled through the multifunction information center, or the touchscreen unit. I just figured since you're able to electronically lock the system from starting through the unit, if the unit stops working, it wouldn't convey any starting. I hope I'm wrong.

It seems that the touchscreen unit has given out for some people with them, so it makes me concerned that it could happen when I'm out on the water.

That's interesting. Thanks for sharing.

I powered my screen on the other day and not all of my trip values are being reset. Which makes me think that the touchscreen unit may not be getting the surge.

My main worry is the unit blinking out on me while I'm riding, sometimes far from help. Since then, however, I figured out a contingency plan should that happen, getting me back to safety and recovering my ski.

FWIW, those touchscreen units are still backordered with no ETA.

Hi musubi
I think because I'm such anew member I'm not able to send PM's I have now check my sets may you can try again,
I have bought the online service manual for my 2023 but it doesn't have a full diagram unfortunately
Cheers 👍

Shucks, I still cannot message you.
Thanks for the reply I attached a snippet from the Service Manual ( Connection.pdf ) which shows the plug going into the touchscreen unit (Multifunction Information Center), and which wires are the positive and negative. I'm not familiar with the technical portions of low voltage stuff, but if we placed a surge protection between this power (positive side?), would that address the issue you think?

Another way I thought of this is, what if we connected the unit's positive and negative to a completely separate battery, isolating it from the stock system altogether. Would this work as isolating the unit from spikes?

My email is [email protected] if you'd like to continue through email, as I know this thread was more for low fuel alarm issue, vs the data reset.

Hi

just wondering if you guys have access to the wiring diagram/schematic drawing of the 2023 FX series?

I'm willing to purchase

I've a 2023 FX Cruiser HO supplied in the UK, with the infamous, premature fuel level sensor with constant beeping with around 45% fuel left and the fuel trip resetting it's self when restarting the engine.

Trip information is still present on shut down, still present on powering up the ski, but zeros on start-up of the engine. My theory is a power surge on start-up upsetting the brains of the touch screen zeroing the trip computer also possibly this could be the cause of so many touch screens being fried. So need a schematic diagram of the full wiring circuit to put DC to DC converters in where required as anti surge protection circuit.

So any assistance would be greatly appreciated
Cheers 👍

I have a 2022 FX HO and I purchased the entire Service Manual. Your ski and my ski should be identical as far as electrical diagram and components go. I tried sending you a private message with the diagram attached, but looks like your settings for private messaging aren't enabled.

If you can either enable this or send me your email, I'll gladly send you what I have for the electrical component/diagram. Let me know.
