Jump Start without removing the seat

So I think I am having problems with something in my ingnition system. Not sure what or maybe it is the charging but heres the problem. I was at the gas station this morning and the battery appeared to drain from just sitting with the bike on aux for about 10 minutes. Needless to say I had to jump start it, a guy had a box to help. But since you have to remove the seat to get to eh battery this is not the easiest thing to do when I only have one key(I know I need to go get a second one made)

I read int he manual that there are points on the outside you can use to connect to to jump the bike if needed. The pictures are lousy though. Does anyone know where these points are and could you put a picture up showing them clearer.

As for the problems, I am going to have the battery looked at this weekend and then we shall see whats going on but I have had to get a new battery every season and I bought a trickle charger but it must not have been hooked up all the way, I just rode about a week ago so it should not have lost charge but alas it had...

As far as I know there are no points on the exterior of the bike to connect the positive lead to. I'm guessing that what you are referring to in the manual are GROUND points.

That said, it's not recommended to leave the bike on aux or in the on position for long. Your battery is likely dead based on what you said. You didn't say though - maintenance free or maintenance type battery?

To give you an idea of the difference between a new battery and a "dead" one - Old battery would refuse to start the bike if it got below 12.3 volts, new one still cranks well at 11. A new battery prevents jump starting or pushing ;-)

Last week I finally decided that my old battery was officially DEAD. Went to sears and bought a new AGM battery. While I was in there I forgot to pull the ignition key and left the ignition ON (oops). Went to best buy while I was in the area... around 1/2 hour later, the bike was quite dead. Learned that push starting the bike IS possible... I couldn't use the new battery because it needed to sit for a bit with the fresh acid and the manufacturer recommends a charge before use.

Yesterday, I got home from work and took the kid to the playground while the wife was making dinner. Once again, left the key in the ignition (nature was calling when I got home...) It was probably at LEAST 1/2 hour (I'd guess more) before I pulled the ignition key - bike started right up, no issues - twice (didn't try after that, didn't wanna run down the batt too much and risk damage... voltage after second start, ignition off - 11.3 volts)

All that babbling to say - Jump starting - requires seat pull. And you probably need a new AGM battery (which you MAY be frying with your charger if it's the wrong kind...)

There shouldn't be any reason to pull the seat for a jump. Remove right side cover, place positive jumper lead on the starter solenoid stud; place negative jumper lead at a suitable location away from flammables, and away you go. The owner manual specifically calls this out.

When I got my BatteryTender, I rigged up a second connector with battery clamps. No seat pull or side cover removal needed if I require a jump now.

Curtis,
Are you saying that you don't use the key to turn the bike off? IMHO that's a bad habit to have. Thus, the leaving the key in once in awhile. Again, just my humble opinion.

Can't we use the terminal on the starter motor to jump start?

Well it was fine all day then of course when I really needed it it would not start. We tried jumping it to no avail. Definitely did not make the wife happy(we missed the reception at the wedding I was supposed to meet her at) So I left the bike over night. Today I picked up a Maintenance Free Battery from Sears. They put some charge on it for me about an hour on their trickle charger. Was not quite enough to kick but sounded close so we jumped it. I was able to get it running. It is now back in my garage and will sit on my trickle charger for the night. We will see how she is in the morning.

I am going to open a new thread on what I think might be the problem --- See LED SaddleBag Lights.

Yes, you can use the terminal on the starter motor as a positive lead and any ground point as the negative.

Sorry definitely not a mechanic. Do you have a picture that you could point out where. "the terminal on the starter motor" is?

It's the only wire terminal on the starter motor-real easy to find. Now about that Sears MF - When I purchased mine, I think the instructions clearly stated to charge only after the acid had a chance to soak into the glass mat for several hours then charge fully before locking in the caps on top of the battery.
bypassing these steps with reduce the capacity and life of the battery.
