Why does my scooter hum, but not start?

by Lauren
(Memphis, TN, USA)

Scooter only makes small humming noise when attempting to start, but that's all! Any help or suggestions you can provide would be so appreciated!

I just had my TNG 50cc scooter serviced about a month ago, and I can't afford to take it back so soon. It was working fine for a couple of weeks, then I was gone for a week and a half, and when I tried to start it, it was dead.

I am not mechanically inclined, but I would be willing to try to work on it myself, I am just hoping for pointers on the best place to start.

Here are the facts as I know them:

1.) It has plenty of gas in it, as it was only used for short distances; however, no new gas has been added since servicing about a month and a half ago. Can gas go "bad" in that amount of time?

2.) The service shop, among other things, replaced the starter.

3.) Since getting it back, it has been leaking something very slowly -- that is, in a month, only a small spot has formed under the scooter. When I inspect the liquid, it is a greenish color.

4.) We just put in a new battery a month ago; could it have died already, or need to be recharged?

That's all of the information I can provide. Thank you in advance for helping with this!

Hey there, just stumbled across this post. Did you find out what was wrong? I'm actually in the same boat now. My scooter was serviced a month ago, and then it wouldn't start a few weeks later (after one week of not riding). No leakage or anything, but I'm also hearing a humming sound.

It sounds like a dead battery to me. I would try recharging it and see what happens. It should at least click when the solenoid engages. Humming tells me that it doesn't have enough power for that.

Battery Tender Junior in package

A battery tender like the Battery Tender Jr. can make all the difference in whether your scooter will start right up each spring, after being stored for months.

Just about every scooter owner needs to have a battery tender, sometimes called a trickle charger. Unless you are lucky enough to live in a climate where you can ride all year long, chances are your scooter will be put on ice, figuratively-speaking, for at least a couple months every winter.

One of the key steps in winterizing a scooter is to protect your battery from draining during its "rest" period. This can – and will – happen if you leave your battery sitting untended in your cold scooter over the winter, even if it's in a garage or shed.
