Hi guys, haven't been on for a while, hope everyone is well.

I have a 2003 Tuono Fighter and it's the most fun bike I've ever had! Hadn't used it for about three weeks and yesterday it wouldn't start. Battery is about a year old, spent the winter out of the bike and looks tip top according to the optimiser. Everything looks good until I press the starter and all I get is a click. Doesn't sound like that dreaded battery dead click! Was fine last time I used it. Rang local dealer who said it's probably the stater relay, try putting a screwdriver across its terminals and see what happens. When I did this, it immediately tried to crack over a couple of times but wouldn't start. When I put the screwdriver across the terminals now, nothing happens. Any help or advice would be greatly appreciated. Cheers.
 
considering you now have nothing at all my first thing would be to check the fuses.as far as a click its probably the battery is gone or that your reg rec is shot.
 
No farts or anything at all. First time I did it, there was a decent spark and it tried to turn the motor over. Now there's nothing. I can feel power going through it when i hit the start buttonbut apart from that there is nothing. I wondered if it had blown a fuse but my guess is as it did try and turn the motor over the first time I did it, the relay has gone and ive blown a fuse as well now?
 
I'd say the battery has gone flat,..those optimisers are'nt the best,ya know.Give it another charge and try again.Gen1 starter relays are notorious for failing.They sound like they are working but the contacts are piss poor.Could be yer problem,it puts a huge strain on the battery.
If you get the bike running,it would be a good idea to check the battery charge with a multimeter at the terminals.Should be around 14v d.c.Dont rely on the voltmeter in the clocks,...it tells lies.
 
A dud battery will drop overnight Smin. One thing Tuono's need more than anything is a absolutely 100% tip top battery. If this chaps bike [tuoldo] still has all the old connections on as well, well that makes it even harder to start them. Good battery, 100a starter solenoid and all the ***** connections removed and crimped is the way to go :thumbup
 
Gets better nows. As sure as I can be that battery is ok. Had a look at the main 30 amp fuses and im pretty sure one of them had gone so replaced it. Bloody thing started then! Swtiched it off to tidy up etc and put things neatly back where they belong and the damned thing won't start again now - just back the the dreaded clicking. Still no sign of life if i put a screwdriver across the solenoid terminals. Any further suggestions please? Cheers
 
Might just be one of the cells on the battery.

I was once told that the ***** falls from the side of plates within the battery during normal use.

When it is thick enough in the bottom of the battery, it call short out one cell, making the battery useless overnight.

Dont know if its true or one of those ********* things they say to get you to fork out for a new one.
 
so bike started fien, then you had issues once rebuilding?
one thing that happens (apparently) is the starter relay get's tarnished - happened to mine (2k miles in 4 years) since i use it every day my slow starting is sorted. but thsi should have been sorted by screw driver terminal trick.

Also check you negative and earths on the engine and frame - a loose one will give intermittent issues you describe. :dunno batteries aren't usually intermittent, but agree with post before they go overnight, but don't generally come back up again.
 
Take it from one who knows and found out the hard way, it will be your battery, no matter how much your charger tells you it's healthy.
Running it briefly will not put back the power you just used to start the engine, As Liam says check your earth continuety, then get a new battery.
