Hello All, Newbie Suzuki person here. Yesterday the battery light came on. Checked voltage at battery and alternator output terminal. About 11.4. Pulled alternator (that was fun!), and had it bench tested. Output was fine. Reinstalled, and all was fine. Output about 14.4. Later that evening the light came on again. And, once again, about 11.4 volts. Checked for key-off drains, only about 50 ma. Pulled and cleaned, again, the two wire connector on the alternator. No improvement. B/W wire is showing battery voltage while running. R/W only showing about 0.5 volts. Charged battery for an hour, then the battery light went off at about 1500 rpm. Came back on at idle. Put VOM on battery, but it showed no voltage change with battery warning light on or off. Okay, now I'm truly puzzled. Any ideas?
