ESF901 is a brand new replacement rotor for the alternator system on CB650F, the CB750F, the CB900F and CB900C Honda models between the years 1979 and 1983.

Check the OEM rotor resistance between the slip rings with a multimeter: if it is less than 4.3 Ohms you can be sure that the rotor is bad. Typical symptom: no charge to the battery. Often when the rotor fails due to internal shorting (resistance less than 2 Ohms) it will take out the voltage regulator/rectifier.

This rotor is a direct replacement for the OEM rotor.
