Jump starting

[Premature Accelerato]

Does anyone know why or what would be the reason that I could not jump start my bike using jumper leads from my car to my bike. The leads were on correctly, the car has a very good battery and the car engine was running. But no way could I get my bike to start from it. Ive since put my battery on the charger and it has recharged but I will get a new battery sorted before winter sets in.

You have probably fried the bikes electrics. Check fuses.

Connected correctly shouldnt blow anything since your regulating 14-15volts max into the system UNLESS there is existing electrical fault in the bikes electrical system .

Check power to start soliniod on the smaller cables when ignition on and start button pushed is a good start.Does soliniod activate.If has fuel pump does it prime up when turned ignition on.Try with clutch pulled in also incase neutral selector issue and side stand up.

I dont think there are any faults with the system as such. Once I had recharged the battery everything was fine. If the fuel pump had not primed would that stop the bike from starting. I would think that the car battery would at least have primed the pump but i can not recall what it did exactly at the time as I was a tad grumpy that the missus and I had to delay our ride (and when your friends take your kids away for the day you jump on your bike as fast as you can before they change their minds).

Probably just a bad connection, make sure the leads are positive to positive, negative to negative, wiggle them on there so they bite through any oxidation/corrosion, if you don't get a good connection the starter won't be able to draw the current it needs to turn over (but lights etc may well turn on OK at least until you hit the starter).

Also, sounds stupid but you wouldn't be the first...
You forgot to turn bike on.
You forgot to turn kill switch off.
You forgot to put it in neutral.

Not all jumper leads are created equal. A "Warehouse" set will not provide instant full charge to start the bike. Even the car battery you are getting the jump from ... is not big enough to give the "kick" charge to start straight away. Assuming the leads were corectly connected ... a few minutes of running the car with the leads attached, will be required to start the bike with a dead flat battery.
Heavy Duty leads ARE worth the money ...

So if I buy the same "Warehouse" set from Repco or Supercheap they will then work? Actually know some people that seem to believe that.

Sometimes, too, if the battery is dead flat it won't start being jumped either. Not sure why but this does happen - maybe the more electrically enlightened can explain?

It is possible to make your own Heavy Duty ones ... you can buy the thick power cable from most electrical outlets. The clamps are available at most auto electricians. The actual assembly of the leads may require soldering ... but the auto sparky will do that in a few minutes. For a few $$$. Still cheap GOOD jumper leads though.

Hmmm. My leads are relatively good quality and ive used them to start other cars with flat batteries. I wonder if the contact area on the bikes battery terminal was to small as they are piddley compared to the cars terminals which have those chunky cone shaped ones. If that was the case, how the hell could you get a decent contact area.
