I purchased one of the few remaining 63 Crown Convertibles about 4 weeks ago. It had charging problems. For peace of mind I decided to replace just about everything related. I first had the alternator tested. It was not giving a full charge. Replaced it and still had a charging problem. Then I replaced the battery and cables. After replacing the voltage regulator, I noticed the stock amp gauge moved to where it should be in the charging position. Now when I turn the headlights on, I notice the gauge bounces around in the charging position sporadically. Does anyone know what this is? Am I damaging the system?
