Hi guys, I scored an electric scooter on trash day. *(A Schwinn zone

Of course the SLA batteries were toast. *(2 X 12V @10A-hr.) *But I’ve

throw something out?) *4 x 6V @12 A-hr. * *I charged up the old
batteries but found one of those was dead also. *(It refused to have
any charge pushed into it.) *So I figured with three I’d have 18V

Now here’s the problem. *There’s an electronic speed control (hidden
somewhere.. I haven’t found it yet.) And there must be a low voltage
cutout in the controller. *So when the current draw drops the battery
voltage below some point the controller cuts out.
So I’d like to find out first where the speed control is hidden. *And
then I’m hoping I can hack it and drop the voltage cut-out.
I’ve done a few web searches, but I mostly find sites where they want
to sell me something... nothing useful. *Any hints on finding
schematics for something like this would be appreciated.

As a side note: I took apart the thumb throttle control on the handle
bar and discovered only a pot. *The sad news is that it looked like a
little trim pot... I guess those last a bit longer than their 200
rotations spec.

integrated controller in the motor?

I think that's what it must be, several (three or more) wires head
into the motor housing. It's says Currie Electro Drive on the
aluminum cover but no numbers. There are four screws holding the
alum. cover to the motor. Of course I can't take one of them off
without taking the whole back end apart. :^(
