Hi all

I am still trying to get me bike back to a healthy state. I just fitted a new battery and when I turn the key there is a clicking noise that comes from the two small boxes behind the ECU & fuses under the seats. Any ideas what that would indicate?

am off to the ducati website to get some diagrams.

cheers

Conor

Sounds like a flat battery to me!! Or possibly a dodgy connection somewhere from the battery to earth perhaps.

Did you get the battery mail order? Has it had a charge?

[conor]

Thanks for the quick reply

Battery came mail order, according to my battery charger it appears to have at least a half charge (but it is a car charger so not ideal)....do you think it should need charging? (its a YT12B-4 gel battery)

As for connection from battery to earth, is there anyway I can check? Currently it has two cables running to each terminal...I'm assuming thats right

Thanks

Conor

not too sure about the battery code but the normal battery is a YB16 which means it is a 12volt 16 amp/hour battery.

If your battery is not a 16amp job it may not have enough grunt to turn the engine over, however as I say I don't know how the code works with gel types, perhaps someone in the trade can give you a definitive answer

We are talking ST4S then are we? Although if the ECU is under the seat then perhaps not.

Can you measure the voltage across the battery terminals?

Does the headlight come on brightly and then dim when you try and start the bike?

Why did you need a new battery in the first place? Could you have a regulator problem perhaps?

[conor]

Its an ST2 (sorry I should have said). The code is the same as the battery I just took off it which was fitted early last year byt the garage.

I don't have a voltmeter at the moment, but have put it on for an extra charge.

The battery needed replacing as the previous one wouldn't hold any charge (neglect on my part). Don't know if it could be the regulator, guess all I can do is see if it takes more charge. If that doesn't help I guess its mechanic time.

Thanks for help

Only the 4S had a gell battery, dont know if this means anything though!!

Give it a good charge overnight. If the bike will run then measure the voltage across the battery with the motor running at about 3000 rpm. Your meter should read about 14 ish volts. If its 12 ish or less then the regulator is playing up or possibly the connector leading from it.

The two black boxes are the ignition/ECU relays. They should click once, when they pull in, but if they are repeatedly clicking then there is a problem.
Are you getting the fuel pump priming? a whiring noise from the tank.
Are you able to turn the bike over?
I'd give the battery a good long charge. If your car charger has a low setting then use that.

[conor]

Thanks guys

It should be the right model (or the mechanic stitched me up ).

If I recall correctlly there was the sound of the fuel pump priming, but the ignition button had no affect.

I have put the battery on for charge, will see how it works tomorrow (or sunday).

Thanks again

Conor

Check the connector in the back of the solenoid.
The solenoid is on the lower right hand corner of the battery tray.
Behind it is a small white connector. Check this is secure and clean. You may have disturbed it swapping the battery over
