Well, I was working on an Razor E300 scooter and first off the batteries were dead. Well duh, that would explain why it won't work. However what was interesting is that I noticed a heatsink on the control module... I wonder if I should open it and would anyone notice...
Anyway I did see videos about the E100 scooter which has two relays. From what I gather, it seems that one relay is to turn on the motor, but the other one I'm not sure about. Whether this translates to the E300 I don't know. The heatsink seems to indicate it has transistors, alas it still has at least one relay as it clicks.
I was also wondering if it were possible to add regenerative braking for riding it in hilly places, but that got quickly dashed by the ratcheting mechanism of the rear wheel. Oh well. The newer direct drive units seem to be the way to go, and not this chain drive ⅓HP motor...

I thought I found a reason to open the box but turned out to be due to the charger circuit telling the scooter to not go when it's plugged in. Drat. Thought I was getting somewhere when I got the batteries to read out 13.x volts but nope. So with the charger disabled, it ... well ... tries to power the motor, alas unsuccessfully. Battery voltages plunges like a rock, so we know the batteries are still sick, though at least it's still drawing some current while charging...
