Question about Transport Schwinn Rechargeable Portable Scooter

3 Answers

Schwinn s-400 scooter no motor activity.

I purchased a new Schwinn S-400 electric scooter for my kids 2 days ago. We read the instructions and plugged in the charger. The light stayed solid green instead of flashing red like the instructions state. I am an electrician by trade, so I grabbed my Fluke multi-meter and ran a few tests.
1: I am seeing 27vdc at the charger.
2: The batteries read 0.00vdc at first, 24 hrs. later they read 12vdc
3: 40 amp fuse is good
The trouble is the motor should turn with 12vdc at the batts., but I get no reaction to the throttle and there is no indicating lights on at the throttle handle. The lights activate only when charger is connected and on/off switch is "on". When I unplug the charger and switch to "on", the lights, motor get no reaction.
Please help. I do have a 90 day factory and a 1 year Pep Boys warrenty, however I would like to hear from the "real world" first.

    have the same problem with second scooter from store--green light on charger from beginning, no charge to battery that will get it going.

    Have issue. No lights on throttle, read 24 volts on battery, 27 v on charger. No motor activity. I beeped out all wires, brake wire is working also. I'm thinking it's the controller? I found on for 37 dollars, I do not want to buy it unless I know that is the problem. Anyone else have this issue? Thanks

    I just bought my daughter one today, brought it home, hooked it up and got absolutely nothing... I'll probably take it back to the store in the morning.

    I have the exact same problem as well. I bought this from WalMart, and the f-ing scooter doesn't work for anything. What a piece!

Schwinn S400 no power

The batteries are dead. The battery in these scooter need to be kept charged or if not in use for a long time charged every 3months. Otherwise, like what to you, they will go dead. The chemicals in the battery have deteriorated to the point where it won't hold a charge. Replacement batteies are probably available at:

Schwinn S180 won't charge

NashvilleDan, this scooter has 2 12v 10 amp batteries in series, you should read over 24 volts at the charging hub if the batteries are good. I would think that if the scooter sat for over a year you have bad batteries, They can be purchased at battery plus.
