XLR connector pinout for scooter charger

[Richard J Kinch]

Looking for the pinout for the 3-pin XLR connector that is used for the 24
VDC charger on import electric scooters, such as http://www.ebladez.com .

It's just + and - from the wall-wart, but I don't have the charger, just
the scooter. For now I have to jump my lab power supply directly onto the
SLA batteries.

Check the connector with a multimeter, and that should give you the
polarity, and which pins are used.

More to it than that -- see my other self-response.

Answering my own question, I discovered several sources of this information
on the Web, mostly having to do with powered wheelchairs, which typically
use the same 24-volt SLA batteries and charging system.

XLR Pin 1 = Battery positive.
XLR Pin 2 = Inhibits vehicle operation when pulled to battery negative.
XLR Pin 3 = Battery negative.

Pin 2 just lets the unit sense when the charger is connected, and disables
the drive, so you don't run away with the charger cord attached.
