Hello all Been while since posted on the forum, but I am in need of advice. I replaced the battery on my 899 this week, as despite it being on optimate for 3 months, when I tried to start it it refused. The replacement battery was direct new replacement, exact same model YUASA YT7B-BS battery... although was bought from ebay! I stuck new battery on, and my dash lit up like below: - Gear indicator flashes a dash at me, doesn't show anything else even when changing gear. - The DTC and EBC indicators also just show a flashing dash. - ABS and engine lights stay lit even when bike is started. - To start the bike i have to hold in the clutch as it thinks it is in gear even when it is in neutral. - Warning triangle above race mode. Once bike is running it seems to be fine, will change gear and sounds like it is being fuelled ok. the first thing i did was charge up the new battery as thought maybe it was slow in charge, but even once fully charged i get the same. I did read something somewhere about lack of voltage could cause this? could i have a duff battery maybe? wasn't sure if anyone else had encountered this? thanks
For sure, the gear sensor needs recalibrating. The memory has wiped with the flat battery. The rest of the indicators could be related, but the recalibration needs doing first.
To answer the Duff battery question. What is the battery voltage before you start the bike and what is it when running? It should be as close to 12V as possible, upto 12.8V for a fresh YUASA YT7B-BS battery. If it in low 11's then possibly undercharged or damaged / worn. You really need one of these machines to test a batteries capacity to start a bike. The example below is about £15 from Ebay or Amazon. As others have said it could be that the data has been lost due to no battery. Lots of battery powered software devices can crap out if they try to write to a chip with low battery. Typically the routine could be as simple as date or time being added to a EEPROM, but it miss writes and crap happens. I've seen this with data loggers, alarm panels, car Hifi and numerous other stuff that runs on batteries either as standard or during a mains failure.
Just re read the OP. In race mode, the rear ABS is deactivated and the warning displayed. Try a different riding mode... that should clear that question. Until the display reads "N", then the interlock with the sidestand won't clear, hence needing the clutch to be pulled in. I don't think there needs to be a battery debate at all other than I'm not a big fan of leaving optimates connected permanently. The bike has started, it didn't before. That debate is done
cheers, i have read about gear sensors needing to be re calibrated, hoped that wouldn't be the case seeing battery was only off for 10 secs from what i hear that needs a rolling road? is that correct you were correct, when in sport EBC and DTC appeared again, still have the warning triangle tho.
thanks i do have a multi meter but haven't checked voltage yet i did try charging then chucking old battery back on, just to test it wasn't a problem with new one, but the issue is the same, and wont start at all, which tells me the old battery is totally fubar'd
Nelly, not starting a debate, just telling how to check a battery..... any battery. He raised a concern on charging slowly, that was all.
That little gadget I mentioned is great for checking all vehicle batteries... it allows you to check the useful capacity, much more important than volts. Note even a furbar battery has over 3/4 of the chemical energy of a fully charged one, so be careful how you dispose of it.
The warning triangle usually indicates an error other than one reported by the engine ECU. The gear sensor issue could be causing that to illuminate as that runs thru a different ECU.
Just an update, still have been unable to get it working. tried a few methods i found online to allow bike to "re-learn" the gears, but so far none have worked. Interestingly when i first start up the bike after a few hours, the N light and gear indicator flashes like it is thinking about it, but then goes back to a blinking dash symbol. The EBC and DTC indicators are also vanishing and becoming blinking dashs after a few minutes regardless of what mode bike is in. so it seems it has to relearn more than just the gears i will be taking bike to local ducati specialist next in hope they can sort, if not the 150 mile round trip to nearest dealer modern bikes eh!
Your showing as living in Colchester and you have one of the best people actually in Colchester V-Moto is in Colchester and is an independent Ducati specialist , pop over and see him, fantastic chap and highly reccomended http://www.moto-v.co.uk/ Glenn is the fella and they are in the cowdray centre off cowdray avenue
just in case anyone else is interested. this turned out to be a faulty gear indicator, not sure if faulty before battery was replaced, or failed at same time, but it was this that was preventing the re-learn process from running (i think cpu also needed a reset) but glen at motov reset system, but it refused to enter the gear learning process he had a spare sensor kicking about for another customer that we plugged in just as a test, and instantly started displaying the C required to teach gears again so ordered up a new sensor, when it arrives will take it back to glen so he can run re-learn process
Have you tried it since? Sometimes you can find that something works with a new sensor but it was the connector not making proper contact due to light oxidation that was the actual problem. So, it may be that putting your own sensor back in will sort it.
I had the same issue with my gear change indicator which made the bike run rough and gave false gear indications. I took it to Glen at moto V who replaced the sensor for me and carried out the re-learning process while the bike was on a paddock stand. Glen is really clued up on these things and comes across as a genuine nice guy. According to him this is a fairly common fault on the panigales and he's changed loads of them. I received really good honest service from Glen and as from now on I wont be taking my bike anywhere else.
all now fixed new sensor and glen's magic did the trick, bike got serviced at the same time. yup glen's a top bloke, lucky to have him in town.
