Hi , I am wondering if anyone has run into this situation before on a 90 series. My alternator light came on my dash so I pulled it apart and found the Voltage regulator out of limits. So I replaced it and I did do all the checks on the stator, Rotor and rectifier bridge and all passed. So I was harrowing and hit bump with the headlights on and all lights went out for 2 seconds then came back on and so did the alternator light. I am sure it has once again taken out the Voltage regulator unfortunately . Any thoughts where to start would be helpful. Its so hard to duplicate as it seems that its only when you hit a rough spot that this occurs .
