I'm seeing 13.2v on the buss when the engine is running, but the charge light is still on (even with the diode). Answers to two questions might help me debug it: 1. What voltage should I see on the buss with the engine running? 2. The picture on the schematic seems backwards to the actual alternator, and there are no markings on the connector. Is there a way to test which terminal is the sensor (direct to battery) and which is the idiot light? Note: The alternator tested fine a few weeks back, but I guess I could have fried the internal regulator since. John Slade (coming down to the wire)
