Dead Battery

[sephy666]

I woke this morning to find my battery dead.

I have an 06(K6) Sv 650S. I have Heated Bargrips fitted but they were not left on over night. My battery is dead I think. The fuel system starts up and the Lights work, but it konks out dead when I try to start it

I don't suppose that you keep it on 24hr charge by any chance. Invest in a bike specific charger and just hook it up all the time you're not riding. You might be able to recover the battery this time by the sound of things.

Does sound like the battery. Do your lights dim when you try to start? I mean really dim, so you only get a dull glow from the headlight? If so, it backs up the dead battery theory. They don't live as long as car batteries.

As IP suggests, a charger might bring it back to life.

It's not in gear is it? ;)

[Kilted Ginger]

Cuould be, in gear, or sidestand or clutch switch failure, the lights etc would dim and go out if it was the battery not cut out dead.

I used a trickle charger from Halfords, was £13 I think, and kept it plugged in when not using it.

got a charger you can borrow if required.

Coincidently I have had the same problem with my battery.
Bike is a 03 plate 650S with a one year old battery. Battery was connected up to the Optimate from Nov last year til beginning of April. I have been out and about on it numerous times including a 250 mile trip.
Last Thursday it wouldnt even kick over and lights plus dash disappeared. Tried it again today after charging since Thursday & its still the same!!!!!!!!!
Havent tested it with a multi-meter yet though.

Sounds daft I know but exactly how do you bumpstart your bike as I tried this last year and got nowhere.

Thanks.

Same way as a car as far as I know, never had to do it myself. In gear 1st or 2nd, clutch in, ignition on, immobiliser off, get someone to push you till your at running speed, let the clutch out slowly and give a wee bit of gas. Make sure the immobiliser is off though, a bloke from work spent 20 minutes being pushed round the car park before he realised!

whenever i have had to bump start a bike i have put it in 2nd gear, got a friend to help push to get some speed up then as i released the clutch bounced down on the seat. don't ask me why but i was told that helps!!!

supposed to reduce the risk of the back wheel locking as there is more force increasing the friction...

must be the weather for it, mine is totally dead today as well. *cries*

[Kirkybhoy]

charger available if required. I can drop it off ( need an excuse for a little run )..:smile:

[fenjer]

offer accepted KirkyBhoy!

[Miss_Undaztood]

I always thought it was easier to bump start things in a higher gear as its easier for the wheel(s) to turn the engine.

I got an optimate, and also have a spare battery! Bought a new one thinking it was dead, only to find after fitting it that my starter had tried to leave the building! Typical Italian! :mad:
Will go check the type to make sure it'll fit if anyone has a dud.

Battery for a SV650 is YTX12-BS.
I got a Yuasa today, £53, which ain't too excessive. Should have bought one last year instead of a cheap Dynovolt!!

Remember & charge a new battery for 24hrs when you get it as they are usually at 75% when you get them & your alternator will not charge them above the 75%.

[gerbrox]

As Stu says, got the same battery and have never looked back.

BTW Suicide Sam's brilliant at jumping the SV..... he jumped mine at least 8 times in teh past at the first GM
