Does having seat disconnected + rear wheel off cause no-start?

Trying trouble shoot.....I just moved and am looking for my multi-meter to see battery voltage but figured I could solve some of the problem by asking here....

I'm currently doing the wheel circuit and ABS fluid change and last night I was curious if I'd drained the battery using the servo pumps so I tried to fire the bike up and all I got out of it was it turned over like 2X and no firing.

I have my seat off the bike, the seat connector plug is disconnected AND I have the rear wheel off the bike. That's the only difference which I would -think- is making a difference...

thanks for any thoughts!

Re: Does having seat disconnected + rear wheel off cause no-start?

None of this would effect starting. BUT stop. Do not try to start the bike with a low battery. It can weld the starter relay or cause other harm that is nasty. Charge the battery fully first. Then do some diagnosing. Sounds like your battery may be past its prime.

Re: Does having seat disconnected + rear wheel off cause no-start?

Okay, found my multi-meter....battery reading 11.8v, so that explains the no turnover.

I have it on the trickle charger now.....

Thanks for chiming in, Beech.

Next starting attempt, have the volt meter on the battery also. If it drops below 10 or maybe 9.8 volts while cranking, it is done. Keep your bike on trickle charge if not used every 3 or 4 days.

Re: Does having seat disconnected + rear wheel off cause no-start?

Sounds good, will do!

I have an Odyssey PC680 in the bike.... those things are typically bomb-proof which is why I didn't consider it being a low battery after only 3 years old but it definitely could be the culprit since I haven't ridden much in the last 6 months.

Strangely, after having the Odyssey on my trickle charger for 2 days, it didn't charge higher than 13.2 and has dropped to 12.8 after being pulled off the trickle charger.

I'll try firing up the bike tonight with the volt-meter to see if it drops super low, like you mentioned...

Re: Does having seat disconnected + rear wheel off cause no-start?

What charger are you using? AGMs generally need higher voltage charger don't they?
I bought the odyssey unit, charge output = 14.7v.
And Float charge = 13.9
Not trying to complicate things, but you likely have some sulfation on on the plates. Might want to keep an eye on it. .

Do not charge an Odyssey with a trickle charger.PC680 requires a 6A charger less you damage it with a trickler.

Odyssey owner's manuals and technical manuals are posted online in the Odyssey website.

12.6V is the point at which an Odyssey needs a charge as per Odyssey.

Re: Does having seat disconnected + rear wheel off cause no-start?

Thanks guys - yeah i'm going to replace it as i'm sure it was toast already.

I'm happy with Odyssey batts and will most likely get another PC680. The charger I'm looking to purchase is the OBC-6A.

Anyone have one of those...?

Re: Does having seat disconnected + rear wheel off cause no-start?

I guess that's the new version my charger, now and then I'll will discharge my 680 to about 12.5v to make the charger enter desulfation mode.. you might be able to revive the old one also. . Might be worth keeping!
