can you jump start a bike with a car?

[Mondeo Man]

Simple question, probably a simple answer.

Thanks

[neatbik]

Yes.

[CaNsA]

Yes,

Jumped a GL1000 from a old Landrover on thursday night.

Depends on the output of the jumper, and the max load of the jumpee.

[pinkyfloyd]

Yup. Jumped a Firestorm from a bugervan once.

Use the car battery. Don't have the car engine running.

Actually, if it's your bike, disregard. You probably know better.

I've jumped started my bike from a cordless drill battery once!

Think i read about this,with smart charge the problem comes on a jump start, when the PCM sees a cold engine, and then a poor battery condition, and can then instantly zap out about 18 volts because its trying to recover the battery. Unfortunately this sudden surge can cook modules.

Thus cooking your bike ! clever system that charges harder when colder or something....

Mums Passat, when running produced 14.2V.

Used it to try and fire my Blackbird.

Unsure why you'd be worried about the car being on... I've never cared, nor has anything bad happened.

Also, sure when I had the Bandit 600, the Rover 25 GTi I was using wouldn't give you any juice from the battery until you started the car. The immob would remove the +12v. Cheap alarm eh.

Isn't it more to do with the amps the alternator will put out that could cause problems?

I don't know, only guessing

As said no problem just don't run the car to be safe.

Alternatively store a little leisure battery with low self discharge around they will jump a bike easy.

Don't do it with the car engine running. But for different reasons than those stated.

In short, if the cars voltage regulator is set at, say, 14.8v and the bikes is set at 14.5v and you attach the car to the bike, the bikes regulator will try to regulate the car alternator output. The car will keep upping its output (you'll hear it rev up), the bikes regulator will keep trying to dump it. The car will win.

used to start my Z550 off the wife's metro 1.0L

and when I used to repair peugeot scooters sometimes the customers didn't come back for them until the end of the week, so
I used to jump them off a 5 amp car charger.

Here's one for you lot then!

Never had a problem jumping off a car battery before but earlier this year my new Absorbed glass mat battery that had flattened after being stood for three months would not jump off a Ford Transit.
These things will only charge on a miniscule AH rate so just assume that a big battery has too much grunt for it to handle - but if anyone knows better it'd be interesting to know.
I was stuck for two days whilst the battery trickle charged from about 8v holding to 14+. Not had problems since but it'd be nice to know why it wouldn't jump off the battery. It was never a problem giving the previous lead acid battery a jump! ???
