2007 Kymco Xciting 500: Jumper cables were reversed. Replaced battery and all fuses. Now the battery discharges, battery charge light in dash is not on, even when engine is not running. Also speedo needle appears to have gone all the way around, is slightly under little pin; when i ride the needle hits pin. Can anyone tell me what could be defective (generator, rectifyer, ...)? Thanks, Pter

The stator produces ac current and the voltage regulator/ rectifier converts the ac current to dc current and keeps your battery charged.

So its probably your voltage regulator.
when engine is off the battery should read 12.5 volts
At idle the baterry should read 12.8+ volts
at 2000 rpm battery should read 13.0 - 14.8 volts

if your not getting those readings your voltage regulator is bad.
you can find them at parts for scooters dot com pretty cheap and they ship fast.


as for the speedo, you may be able to take apart and reset the needle. Some you can't even get to.
so you may have to get a new one.
