I press the starter button,
If there is voltage on the motor and it doesn't turn, is probably needs new brushes and the commutator may be dirty.
My battery wont charge and I just bought it
Hi and welcome to FixYA,
Two possibilities:
- rectifier / regulator combo (most likely);
- corroded, burned, loose connection from the stator to the regulator (likely);
- faulty stator (least likely).
The stator would be producing relatively high AC voltage while revving the bike. The stator output AC voltage are fed to the rectifier / regulator through 3 white wires. Check calls for testiing for the presence of the AC voltage on any pairing of the white wires before and after the connector before the voltage regulator. Check on the regulator calls for checking the battery voltage when revving the bike (14.5 VDC).
Good luck and thank you for asking FixYa.
Rev counter not working
If it is electronic, suspect a sensor malfunction, faulty meter or a disconnected or loose wire. If it is mechanical, suspect a broken cable. You dont give a year or model so it is difficult to be more specific.Thank you for your interest in FixYa.com
After a 2 hour ride
Might have 12.67 volts, but not enough amps to crank engine or light the lights properly. Try putting a charger on the battery, bring it to a full charge. Next, put a load tester on the battery to see if battery is weak or dead cell. If battery checks good, check the charging system. With engine running at idle, put volt meter on battery-read volts, then rev engine to high idle. Volts should climb higher than idle reading.
