2001 Road Glide Harley

Your bike has a stator and a voltage regulator. On the right front down tube you will find the plug for the stator and the voltage regulator, unplug the stator from the voltage regulator and use a meter to read the out put from the stator. I don't know the value's off hand but as you rev the motor the voltage should climb. If it doesn't your stator is bad, major job. If it does measure the voltage on the battery cables, when you rev the motor they should climb to a little over 14V's.
