Will the scoot run with a jump start?

I know you can't push start a 650 but if the batteries very low will the scoot continue to run after being started with a jumper cable?
Also - do you think 18gauge wire can carry sufficient current to start the scoot? Will 12A start the scoot? Anyone put an amp gauge in series with the battery when you're starting?

I can only answer your first question with any authority, and Yes, you can jump start it and (assuming the charging system is not defective) it will continue to run. DAMHIK.

I'd say 18-gauge is much too small. I build a set of jumper cables using 6-gauge; I'd probably go no smaller than 10-gauge and that might be too small.

As far as jump-starting, no issues whatsoever.

An educational thread, for sure. "DAMHIK"...never saw it before the J-man used it. So, how out of touch am I? :D

Save yourself the work and buy some jumper cables at Cyclegear or any other online MC retailer.
In a nutshell, if you don't want to risk frying your electrical system, attach the cables and let the donor charge the dead battery rather then an instant jump. You can run the donor bike, although it needs to be a high idle or better to get useful voltage. charge for five or ten minutes, then SHUT OFF the donor bike (key off, to protect the electrical system) and then start the dead bike, with cables still attached. This is a safer procedure.

If both bikes are running with the cables attached you risk damaging one or both bikes.

If you wish to make your own cables, use cable the same size as used on the bike. (or larger)

Not without special tools. Which no one will carry

If you get some cables, you don't need special tools.Your tool kit has what you need.You might be surprised that many people carry lots of useful tools beyond the tool kit.
I carry a pretty extensive tool kit and I imagine that a lot of members here do too.

The batteries!! I suggest you get someone knowledgeable to show you how.It deserves more then a forum explanation. Or you might try youtube. Video will show you better.

I'm really not following what you're proposing. One - I only have one battery, that I'm aware of. Two - I graduated from Purdue in electronics so I'm knowledgeable about batteries. Three - The tool kit does not have tools which will allow you to remove the cover to get access to the battery. Am I missing something from your post? Have you ever tried to get access to the battery?

Battery

The battery in the other bike or car, that you want a jump from. Ohhh, you are a EE , you should be able to figure this out then. My tool kit has the tools to get at the battery, and there aren't many tools in the BMW kit.The Torx bit you need, is on the opposite end of the Phillips screwdriver bit.
Again, I am sorry, but, it sounds like you need to find someone to teach you motorcycle mechanics.
Yes, I can and have accessed my battery.
BTW, since you haven't accessed your battery, when you do, it might be time to clean the terminals ( dirty terminals are a main reason for "NO Starts), and get yourself a battery tender and use it year round, when ever you aren't riding. The battery will last a lot longer. Although, by letting your battery go dead it has already shortened it's life.

I just replaced my battery. I have used a BMW battery tender for 2 years. Dirty terminals will only cause a battery to degrade if the dirt is conductive and has found a path to ground. I have owned motorcycles for 20 years in my earlier life and for 10 years in my later life and have always done my own maintenance so I really don't need someone "to teach me motorcycle mechanics". I did err and leave my ignition on which killed my battery. You really shouldn't make your above assumptions about someone's ability or knowledge without some basic personal information. Thanks for your input.

Are you sure? Mine has the correct-sized Torx wrench for removing body panels.

Also, it's pretty easy and inexpensive to make yourself a set of jumper cables with 12-feet (or whatever) of #6 conductor (one red & one black) and alligator/battery clips, both available at any hardware/home-improvement center. The benefit of making your own is that they take up MUCH less space than most commercial ones and the smaller clips are better suited to the small terminals on motorcycle batteries. I carry a set coiled under the seat of both my scooters.

I'm going to see if I can get the panels off with the BMW tool kit. If I can, I'll take your advice and make a set of jumper cables. I sure would like to have that option. Thanks for the tio.

OOPS! I have to apologize. The tool kit does have a tool that allows me to remove the side panel. Going to Lowe's today for wire and clips. Did a lot of research for jumper sets and it looks like most use aluminum wire which makes them too bulky. Thank you "davidh" for your help.

No worries! Let me know if you want any pics of what I did.
