12 volt battery should be 12-13.2 volts dc normal and 14.5-14.8 vdc at rpms if you only get 8.5 vdc then the charge system ( alternator /stator)is not working or the voltage regulator needs replacing
To keep things clear for you i've listed 2 things for you to check.
1.
Your bike produces its own power. It consists of a stationary stator with a (pick-up/pulse) signal generator
The rotor/flywheel is mounted onto the keyed crankshaft, and secured with a nut.
This will be on the right side of the motor, you'll have to remove a cover to get to it.
I would have this tested with an ohm meter before you remove anything.
Pulse generator coil resistance should read 70-130 Ohms.
2.
Your battery produces power to start your enegine and run some lights. After some time your battery would go dead if not recharged. Your bike has a Voltage Regulator & Rectifier built into one unit, which some people call just a voltage regulator, and some people call it an alternator.
Your above mentioned stator produces an electrical current called AC power, which probably only runs the headlights, and the rest of that AC power is converted to DC power via the Alternator/Voltage Regulator, which runs the rest of the lights and horn, etc.
Your alternator should put out 13.5 - 15.5 Volts @ 5000 rpm.
Any other reading means your Alternator is bad. Too low undercharging Too high overcharging.
Test your alternator at the battery when the motor is running.
If you need to replace your alternator, it is located under the (nose)front plastics.
Usually a 4 prong plug and one bolt securing it to the frame.
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.
