SV650 Dead battery.

In work about to leave and when putting the key in the ON position, nothing appears on the dash. Zilch.

Threw a multimeter over the battery 1.2 volts, yes ONE POINT TWO volts.

I left my heated grips on, fml.

Waiting for greenflag - apparently its going to be a couple of hours

Tbh not sure if greenflag will charge me for being a dufus, I might just pretend I didnt leave them on and I dont know what happened :S

It was about 24 degrees today and you were using heated grips?

Sorry to hear this! Been there a few times, stomach drops when your bike misbehaves.
Can't you bump start the bike instead of getting Green Flag?

OP doesn't say which year/model. If it's a Pointy with Fi then that's not enough voltage for the injectors to fire so it won't bump......

Oh My last two bikes were carbs so I had to do this a few times. There's no way round of bump starting a F.I. model then? Not even if you run really really fast with the bike?

Can you also jump start the bike with a car battery? Or would that be too much voltage?

Jumped it off a car eventually, greenflag gave me a time of 2.5 hours.. So i rang around.
I dont mind jumping off a car so long as its not switched on..!

It was cold at 5.30 this morning

Yeah you cant bump a bike with fi.
Bumped my cbr a few times with a dead battery.. Saying that each time I was near a convenient hill which made it much much easier.
Makes up for the time I ran out of petrol two years ago at the bottom of the mersey tunnel.
I pushed it out uphill for 3/4 of a mile.. It was either that or £160 for recovery(you arent allowed to use your own recovery in the mersey tunnel) lol

Yes you can jump off a car....as you found out! The voltage on a car is the same as your bike, 12v. Just don't ask for a jump off a lorry!

The reason a fuel injected bike won't normally bump start with a flat battery is that it needs some voltage to fire the injection system, without which it can't work. It doesn't need much so if you've got ignition lights you're in with a chance.

Most older carburetor bikes have separate ignition windings on the stator, so as long as you spin the motor hard enough for them to work it will fire up. Just about the only advantage a Curvy has over a Pointy

Which heated grips do you have? I have the oxford ones which, if you leave them on, automatically switch themselves off just before the battery is completely drained. The idea is so that there is enough power for the ignition to work, but I've always found this wishful thinking. That said, it did used to preserve enough power for the FI to work, so the bike could be bump started. You just had to make sure you did it quickly before having the ignition on drained the last bit of power you had! I used to have to do this on a regular basis (I'm quite forgetful and those blue lights on the dash just didn't seem to register with me) so I became quite a pro!

Alternatively to prevent this happening in the future, you can wire the grips into the ignition so they turn off when the ignition is turned off. There's a handy guide on how to do this with the oxford ones kicking around somewhere on this site, I'm sure a search will bring it up. The only thing I found was with the newer designs of Oxford grips, this used to nacker the controller (still have no idea why, I spoke to Oxford and they just told me to wire it into the battery, so back to square one) but if your grips are slightly simpler in design you should be OK.
