Schwinn Stealth 1000

I have a stealth, and my garage got flooded last year. It worked alright the next day, but sometimes the scooter throttled by itself. So,the day after, it throttled while I was walking it, jumped the curb and landed hard. It stopped working. I just dusted it off today to see whether I could get it running again. It doesn't seem to be charging when I plug it in. Though, if I plug it in when it is ON, the Full light lights up. I'm not sure what's wrong and I am just wondering if I will be able to fix it or just strip it for parts.
I opened it up, but all I didn't know what to do...
Maybe it's a problem with the controller or something

If the motor was not affected by the flood, and you have a good working gearbox, don't scrap it out quite yet.

Let's eliminate one thing at a time: Remove the foot deck, and find the red and black wires coming out of the canvas bag. Trace them to the SAE connector. Note the condition of the connection (loose or disconnected). Separate the plug and use a voltmeter or digital multimeter to measure the voltage across the two wires. It should be somewhere in the vicinity of 36V. Let us know what you find. I suspect that since it landed hard, something has become disconnected. If you don't get any voltage across the red and black wires, you should slide all three batteries out of the bag and check each one individually. They usually solder the wires to the battery terminals and one of those may have broken in the impact.

The original "throttling" problem may have been caused by moisture in the connector from the throttle to the controller. It might be a good idea to check all the connections that may have been exposed to any water. Make sure they are dry and show no corrosion.

It's still possible that this could be a controller issue, but lets do the free stuff first.

Let us know your findings on the battery.

How bad was the flood? Was the scooter underwater? Sounds like an aweful mess!

Hope this will help start you back to riding again.
