>test batteries, 24 volts
>motor moves when hot-wired to batteries
>hook everything back up
>hear the relay in the motor controller clicking on and off when I turn the throttle
>controller still reacts to throttle when the 3-pronged on/off switch is set to "off"
>scooter doesn't move, even when pushing it along like the manual would suggest
>hear the relay clicking on and off while holding the throttle down

I can see a few possibilities:
1. The batteries are actually drained/fucked and I didn't realize it ($12 for the charger, $25-$35 for the batteries)
2. The throttle is fucked ($15)
3. The controller is fucked ($15)
4. I wired something up wrong (Priceless)

So I have a few options
1. Fix it with stock parts
2. Replace the internals with something better
3. Gut it and use it as a kick scooter with a storage compartment

What do you guys think?
