Stock charging system, stock electronic ignition.
Rode the xs about 14miles. Killed the battery. Charged the battery, 12.8 volts after sitting a week. Fire it up, 13.3 volts at the battery. Doesnt change with RPM.
Tested the rotor, 4.7ohms. Battery is smallish advance auto parts 4L-BS.
What should I check next?
Thanks.
 
When reving the engine to 3500 to 4000 rpm, you must see the battery voltage go to at least 14.1 volts, or the battery will never be fully charged.
What resistance do you see when you connect the 2 meter leads together.........................subtract that reading from what you measure at the slip rings to get the true reading.
 
Go through all the tests in Curly's Guide, or gggGary's new improved hip-hop Curly;s Guide from the Tech section of the site. One other thing to consider is if components fail tests it may be the connector and not the component. I've had a couple of factory crimps be bad from age...
 
The voltage does go UP from 12 something to 13 something when you start it? Recheck your battery voltage, move the negative from the battery terminal to the frame, does the voltage reading change? remove clean replace battery to frame ground strap connections. Check voltages at the fuse box. basically you should see near 12 volts everywhere with the key on. If one or more voltages reads more than a couple tens of a volt low; common problem areas; bad fuse holder clips, bad fuses, dirty contacts inside the ignition switch. Dirty corroded connectors "somewhere" in the wiring.
