six months and it won't start

[gregski]

six months ago I had a little crash on my 620ie ( some ass in BMW drive straight in to by back side ), damage tail unit and swing arm. I decided to get it of the road and get some work done on it. done all the repairs and now it comes the time to start it, and that's where problem starts.
after I turn the ignition key one of the two relays keep clicking constantly, all the lights and clocks come on normally. when i remove the clicking right hand relay with the ignition on and put it back it stops clicking, pres the starter button and starter motor try to turn but after a second it stops and relay start to jump again. I'm just wondering is it anything obvious or do I need to go to the garage ?
maybe some one has a similar problem

thanks Greg

Battery.....

[gregski]

battery is new

[giler]

Faulty relay.....

[jimbo696]

Which relay is it?

[Paivi]

Is the battery charged, as they usually come flat as new?

[gregski]

the battery is charged and I took other one from R6 to test.

faulty relay hmmm it happens when I swap them around so don't think is the relay.

and is not the main one and I don't known how the other is called.
when I remove that relay the starter motor turns but bike won't start :(
O and I notice that when you turn ignition key on the fuel pump is not making the characteristic noise

[Paivi]

Give Matt/Al (Unit18 on this and other Ducati sites) a call at Ducati Proteam for a diagnosis. If they can't help, they can come and pick the bike up, fix it and bring it back to you. Pick up and delivery is free...

Hi, if you mean the two small relays mounted next to the battery, they are notoriously weak and can fail, one is the main relay, the other is the fuel pump. When you swap them does the clicking still occur in the same station?
If not its probably the relay, if it does it suggests a more complex fault.
The starter system works through the ECU (see pic) and not a simple solenoid (although it does have that as well) so it can take a bit of searching to find the fault.

just before I reed #9 I went to check again and it is the flue pump relay after I disconnect the plug from the tank it stopped.
would it be worth to take a pump a part ?? maybe it's something simple ??

Emergency cut off switch?

I left a Monster 620 sitting for 12 months once - when I went to fire it up, the fuel pump didn't make it's normal whiring noise.

When I sniffed the fuel in the tank, I found it had gone off, so I drained the tank and pulled the fuel pump out.
It was chocker block full of "gunk" from the stale fuel and wouldn't turn - I managed to clean it out and got it working again, but didn't use it as I didn't want to trust it.

I bought a cheap one off ebay (from a 916 I think) and fitted that - I just used the actual motor / pump as it was the same, but the rest of the setup was different.

Sounds like you may have a similar problem...

I've heard of problems with fuel pumps several times on bikes that have been stood idle. Usually when the tanks dry though.

I was about to take the pump a part this weekend but I'm not well so it will have to wait til monday.

I'll keep you posted

[gregski]

Ok so I took fuel pump out and well it looks normal and clean, took the motor out of the casing and connected to the battery - runs ok so I put it back and plug the pump to the socket but the problem is steel present :/

I'm thinking not the pump is the problem but whatever supply the pump relay ?? but after I disconnect the pump from the bike and turn the ignition on there is 9 volts on the plug so if the supply to the relay was faulty relay will keep clicking no mater if the pump is connected to the bike or not.

or maybe I'm just talking rubbish ??

[Stafford]

9 volts seems a bit low to say the least which would explain why your relays are clicking just like mine did once........battery.

[Jim66a]

You need to check the voltage across the battery terminals, It should be at least 12v. If the battery is reading 12v but you have only 9v at your relay socket then I'd be looking at for a corroded connector in the loom and double checking the earths on the engine. 9v is extremely flat, possible that a cell has failed in the battery. Your relays are clicking because when the relay coil is energised and the switch contacts your battery voltage drops even lower and its not enough to keep the coil energised so the switch contact breaks allowing voltage to rise and re energise the coil...... and so on.

[gregski]

Ok so I went to buy a new battery "CT12B-4" 100 pounds what? !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I'm just wondering is it have to be that particular type ?? or any battery will do ??

and any one knows where I can buy it cheaper then 100 pounds ??

I found this on ebay what do you think ??

100 quid is waaaaaay over the top!

[BluprintZ]

100 squids?? someone is havin' a laff mate, you should be able to get a new battery AND get the system checked out by an auto-electrician for less than that.
As has already been mentioned, there's either a short or corroded connection/earth somewhere on the bike.

£50 is dear unless its a gel one.

[uksurfer]

think i paid £60 for my M600, sold it a month later for £20 :twak:

[Albie]

You was robbed too then LOL:twak:

[uksurfer]

robbed once when i bought it and robbed again when i sold it to Liz! Never mind :spin:

[Gamsa]

Try disconnecting the clicking relay and measuring the voltage across the battery before and after switching the ignition on. This will only be a minimal load but will give an idea of whether the battery can keep up to 12V whilst producing current.

[chris yeatman]

to be on the safe side, why not charge the battery that u have got, because u may be getting 12v with a multimeter but wen u put a load on to the battery it may be dropping volts,
then take it to local motor garage they could do a drop test on the battery for u.
if the battery stays at about 11v then its ok but any lower then its no good.

[Paivi]

I bought a Varta YT12B-BS for my 695 and it was £46 from my local scooter shop. They even charged it for me. My problem wasn't the battery, though, after all but my immobiliser.

[gary tompkins]

Normal lead acid battery for monster £50-60. I paid £62 for a H/Duty varta battery on the trike.

Maintainance free Gel type around £20 more

battery is new

How new?

New as in prior to the bike being smashed?

If it's stood for 6 months un-charged the battery may be knackered. Immobilisers gradually drain a battery until so flat they become virtually un-salvagable. That's why regular use of an optimate if the bike's laid up is advisable, unless you like replacing batteries every few years for a laugh.

Current battery on trike is 5 years old and doing fine + optimate.

[gregski]

I got a new gel battery today 50 pounds it looks like a good price, fitted in but the problem is steel there.
I measure voltage on the main relay coil and is 12 v but on the pump relay is only 9 ??
I check the neutral links the the engine and they are ok. Try to trace the cable from the relay coil but it's one hell of the mission:/

maybe someone has got a wiring diagram for 620ie 04 Reg?? I've got old 900 and is not the same
As I'm an electrician I will try my luck first.

Thanks Greg

[gregski]

I found one one a web but it's the same as the 900 I had :/ and there is no fuel pump connections on the drawing also all the colors codes are different. I think I pass on this stage, spoke to ducati proteam they will pick up the bike on Tuesday.

Thanks for your help guys.

Greg

[gregski]

As always Alex and Mat got it sorted for me, it was faulty ECU :/
I supposed to get the bike back today just after 7am, van turn up on time but it did not come of it even.
My MOT is expired which I notice only last night but was to late to call proteam to cancel delivery and have MOT done.
so bike has gone back to the garage and it will be back on Tuesday I hope
