Hi guys,

I think Phillip is mostly right...and I am splitting hairs..sorry Phillip....

the leds are supplied by low voltage side of the csb charger, they are switched on by a signal from the battery pack, the wire that comes from the csb to the battery packs works as follows:

open cicuit=red led, hence why red when battery removed.... and fail safe.
fully switched to zero volts=led off and no charge hence fail safe.
switched to approx 3 volts between wire and zero volts=greenled and charging.

the high voltage, 100 volts dc is a separate branch of the power supply.
You can get a green led and no charge condition! if the high voltage side fails.

If you know the pinout and are brave enough, you can force a charge into the pack if you have a 100v 600 mA supply, or some other form of current limiting...i.e. 60 watt lamp..
Although you can only partly charge this way, 5-10 mins to get get over an undervoltage condition..AT YOUR OWN RISK!

for technical details, the high voltage side is current limited to 600 milliamps.


As long as there is >69 volts on each battery and there is nothing wrong with the main boards then the segway should respond to the key, it will not start but it should recognise the key and beep on application.....at least mine do when I supply them with a home made power supply (6 model aircraft batteries on each side)



I hope this helps, and I don't mean to undermine anyone..

Best

Ian
