How to get going on a dead battery?

Hello guys, picked my bike up yesterday, was running fine, got on it this morning put full chock on no throttle as it was a chilly morning, and the bike would not start what so ever!

I can hear this constant buzzing noise, anyways a man on my street (ex biker) gave me a running push while i was in 2nd and then released the clutch and it started, i had to go into town for some meds for my ill mother, parked up in a empty car park got what was needed, got back on the bike and it still wouldn't start, i had to ring my ex step dad to jump start it, then i had to ride home like a bat out of hell as if it was on low revs for a little bit it would cut out.


What can cause this?

It was MOT'd yesterday and passed.

Messaged the dealer and he said it was working fine as they ride them out from the workshop daily, but if i go tomorrow they will change the battery for me.

Question is how do i get it going with no help and keep it going for around 6miles?

Sounds like the problem is one of 2 things....

1/. Dead battery......remedy is to change the battery

2/. Charging circuit not working......needs investigation as it could be a stator or the Reg/Rec stuffed.


My money will be more on #2 TBH......although if the battery is not holding a charge..... :?


If you have a battery charger charge the battery overnight which would hopefully be enough to get you back to the dealer......then make them check the charging circuit.....and rectify any problems..... :wink:

Thank you tango, the only problem is i have no charger at the moment, as i diden't think this would happen a day after buying the bugger.


Yeah my step dad is a sparky, but he think's its dead aswell as it seems to be short short circuiting.

I'd invest in a battery charger at your earliest opportunity if I were you......looked after they last forever....so it's always a sound investment....... 8-)

However, it doesn't help your immediate problem........and if you have no output from the charging circuit you'll not be able to bump the bike either as there will be no current to keep the electrics going....... :(

See if any of your neighbours have a charger that they'll let you use?...... :)

I've used car chargers in the past......just disconnect the battery from the bike before charging....just in case...... :wink:

However.....I think that as you picked the bike up from the dealer yesterday I'd be calling them and demanding that they send a van to collect the bike.....and you don't accept the bike back until they've fixed it......and I'm sure you'll find that your consumer rights will back this up..... :)

Hey tango, not sure about this but got something to ask you.


If they cannot collect it would this work?


Some how put jump leads from car to bike, is it possible to transfer some power to the battery and charge mine up like that?

Your step dad must have a multi meter, check the voltage of the battery it should be around 12-13v.


It sounds like you got it bump started already so you should be able to do it yourself, I do with my nsr. Just put your key in ignition on run down the road and put it into first or second. I find first easier because you just put your foot on the gear lever, remember to pull the clutch in straight away otherwise the bike will go for a ride by itself!! You can do it whilst sitting on the bike away just try to find a slope it'll make it a bit easier.

Thanks for the advise, my step dad came back to mine, and managed to borrow a 6 and 12 volt charger,


He does indeed have a multi meter, we tested the battery and it was only producing 6V, which is not correct.

Currently charging it but will still be seeing dealer tomorrow, as it seems the bike hasn't been used enough over the months.


Bump start i cannot seem to do on my own a old man pushed me down the road :3

If it's 6v then you have a damaged battery, not a flat battery...

Sorry mate...been out for a bit.....

Yeah....sounds like the battery is extremely flat.......so see how it is after a few hours on charge.......and also get your step dad to measure the voltage across the battery when you get the bike running......you should see around 14v....which means it is charging the battery......if you see 13v or less it's not charging.......14.5v or higher and the circuit is overcharging the battery....which will boil the battery and kill it.....if you don't see that voltage then the charging circuit is faulty......most likely the Reg/Rec is stuffed..... :wink:

When you have charged a battery they will read 12v for a bit its called surface charge it soon drops off


You also need to try it under load too ie on the bike with starter pressed if it drops below 10v while tryingvto start its shafted

Hello stu, found you was correct before even checking what you put as i just tried it and no luck.


Cannot test the exact voltage just got a alphatek tek 692 which reads 6-12-24-36-48-110-220 VDC.


Rather frustrated at the moment, back on charge it goes....


Just some information, after putting the battery back in it almost started... and the front beams were on which they wasen't this morning.

Yes the headlights was working earlier when i had to jump start it with leads, but when the problem started the lights wouldn't turn on at all when in neutral, and I'm afraid you cannot turn lights off on my bike :/

It'll take a good few hours for the battery to fully charge....so, as Stu says, it'll show 12v fairly quickly....but as soon as you put a load on it ie, lights, starter, etc it'll soon drop off.

Leave it on charge overnight and try again in the morning....by which time it should be well charged.... :wink:

Now here's the thing I was getting at if your battery was flat with not a lot of light but once jumped the bike ran fine with good light output from the lights then it sounds like your charging system is fine and its just a shafted battery

last bit of information for the night,


No idea why but i had to go see if she would atleast give me a few words, put her kidney back in, and she started, let her run for 5mins, cut her off, she started again, then again, then died so guess overnight will give me enough time tomorrow to get to the dealers and get a transplant.


Thanks guys for the advise.
