So my wife and I have 2 Liberty 150s. I went to start them both up after they've been sitting a while and one fired right up, the other won't start. It doesn't even sound like it's trying to turn over at all.

It's not the battery, and it's not a fuse (I tested all of the fuses with a multimeter). It has gas.

I'm no mechanic but it does seem like this should be something I can troubleshoot and fix (with help from the forums!) It ran 100% fine before it sat, and it's been garaged the whole time. (And it's twin fired right up...)

Here's a link to a video so you can hear the sounds it is making when I try to start it. (I can't attach a video; they are too large for the forum.)

If I were to guess, it sounds like your starter relay is chattering and not able to fully engage your starter. I suggest you double check your battery connections are clean and tight. Double check your battery voltage.

As above, your starter relay is acting as a buzzer because your battery is buggered. You say it's not the battery - have you had it load tested? I bet if it was left to self-discharge and wound up discharged (less than 12V) for more than a day or two then it will have suffered damage. Yes, it may appear to charge OK, but when asked to deliver a large current (relay now on) the volts drop below the hold-in voltage of the relay, which now goes off. The volts can now rise high enough to trigger the relay on again - yes, now it's a buzzer.

You can get the battery load-tested - but I can 99.99% assure you it needs replacement.

"Kill" switch is in the run position, yes?
Very cold here in the midwest.....never heard my Liberty make that noise....but my guess would be the battery, also. Most EFI engines like a very healthy battery.
If you have a battery tender - hook it up for a few hours and then try. Pretty cold to be messing with much else -
if all it needs a little top-up with a battery tender.

Our Liberty's have a miserable little 6Ah battery - not much reserve in there after 3 or 4 midwestern winters! If battery tender doesn't bring the scooter to sounds like it's at least trying to start - might be time for a new one.

Let us fellow Liberty owners know what you find.

Switch your wife’s battery in to your bike and see if it starts.

Easy enough. I'll try that this weekend when I have time.

My semi-high-end battery charger went through its desulfating/etc process and thought the battery was fine but sure, not like it's hard to do a battery swap.

I'll report back!
