Ducati 1098s, all show and no go!

[Justices]

No go down to me that is. Bugger!

After solving the issue of the brake locking up the rear wheel in the most inconvenient of places (middle of 4 lanes of in heavy Chinese traffic), the battery that came with the bike was playing up so I bought new Yuasa. The new battery was fully charged. It started the bike first time on day 1 but on day 2 it struggled. By day 3 the bike wouldn't turn over so I put the old battery in (it had been on the charger and was full) and put the new one back on the charger. Unlike the Yuasa battery it has four terminals, two on each side, and in my hurry to get the bike going I connected the positive to negative and negative to positive. There was a bit of a spark and I realised what I had done.

One of the fuses (#15) was completely melted, all others looked fine. I've replaced the fuse and tried both batteries but nothing happens. There is no red blinking light on the dash and the dash doesn't turn on, it seems like there is no power going in at all.

Any ideas?

I would be praying there is another master fuse, 30a or similar that has blown as well.

If not, there is a chance you've blown the ecu

[Justices]

I hope not. Parts for this and the MV are a bd to get over here.

The main thing is to get it fixed quickly. The weather looks good for this weekend and I've only taken it out 6 times in almost 5 weeks due to the crappy weather and I am now down to an electric scooter (souped up to do 62km per hour if that helps)

I'm 99% sure there's a 30A master fuse down by the starter relay/solenoid. Easy to bridge if you're in a jam

According to the wiring schematic, their is a 'Regulator Fuse' (circled red - 8) probably near the Battery (7) and the main fuse carrier (circled blue - 35).

Cheers boys! I will check this out right now. Decent bikes are quite a rare over here due to the archaic rules and £14k you have to pay for number plates. But today lots were out as I looked on in envy trundling along on my scooter.

If this is the fix drinks are on me.

Which bit of China are you in? I go to Shenzhen a couple times a year and I'd hate to ride a bike in that traffic. I'd not really enjoy driving a car in it either come to that.

Yup that sounds about right to me

Shanghai. Shenzhen & Guangzhou have completely banned motorbikes now.

For those that told me to find the 30a fuse... I love you, sincerely.

I had a poke around, found the little box, saw the fuse was shot and got a courier to race across town on a Sunday afternoon to deliver a handful of fuses. The thing started first time and I hooked up a tender cable to the battery so no more fairing removal while the battery sits on a Ctek charger between use.

Made a perfectly sunny day that much better.

Thanks again. Hold me to those drinks!

Bloody thing left me stranded again just after leaving a petrol station. Pushed the start button, it tried to start a few times, the cranks then became fewer until it was just a quiet click sound. Loaded on to a truck and rolled it back to my garage to put on the Ctek charger overnight. It started on first push the next day so I am not sure what is going on here as it is a brand new Yuasa battery. Perhaps a fault somewhere that's draining the battery? I always ensure the key is never turned all the way to the "park" position so I can't see anything obvious.

I should perhaps have saved a few pennies and gone for the special edition. You know, the "Space Ranger" edition.

How are you initially charging the battery? Have you had the batteries tested?

[fergus]

Did you need to fill the battery, or is it an AGM type? Some which are sold as maintenance free, may actually be sold dry and need filling with distilled water, then leaving for at least an hour or so (ideally overnight) to let the plates soak through. Did you leave it to charge overnight on a trickle charger prior to use? If not, you may find that although new, if the battery wasn't fully charged, and the plates inside may have taken a bit of a battering.

[Justices]

Brand new battery and it had to have the tubes of electrolytes poured in. My mechanic picked up the battery and charged it, I am beginning to think he rushed it as he took it in the morning and came back early evening with it apparently ready to use.

If you have a multimeter put it across the terminals read the voltages, engine off should read about 12.6volts (fully charged battery), with the engine revving to about 5k should see just over 14volts but no more than 14.7volts (above 14.7 volts you risk boiling your battery - which is not good), if not when you blew the fuse you could have done more damage than you had thought or the regulator/rectifier is knackered as that's why you changed your last battery as it is showing the same symptoms.

Thank you! I will get on to that and report.
