🔍 Rotor failure check:
If you suspect a problem with the original rotor, here's how to check it with a multimeter :
📏 Measure the resistance between the OEM rotor slip rings .
🔹 If the value is less than 4.3 Ohm , the rotor is bad.
🔹 If the resistance is less than 2 Ohms , the fault may have also damaged the regulator/rectifier.
💡 Typical symptom: No battery charge.
