The continuing saga: I changed the ignition switch. Right. No problem. The battery goes dead, ampere meter reveals discharge - no charging of the battery. I have rebuilt the alternator 6 months ago for similar symptom. Seldom drive the car. I change the regulator, put in a generic Fiat device with same 3 leads (+, -, field). Works like a charm, for a while. Now the symptom is exactly as before - when starting cold, will discharge as though their is no alternator belt. After approximately 5 minutes of running, the ampere meter swings positive and works precisely as it should. Charges at 40 amperes for a few moments, and then slowly comes down to 0 ampere flow while driving. At idle it discharges, and once above 12-1500 RPM, charging like it should. Question: What is happening during the first 5-10 minutes of running that prevents the alternator-regulator from charging the battery? Has anyone experienced this? Jim S.
