Please don"t unhook the battery when running. The alternator (when working) becomes unregulated and can fry things with high voltage. (even fry You) It is a test with a generator, not an alternator. If full fielding it does nothing, the alternator is not working. If it does charge (assumes a good amp meter, or reading of 14 volts or so on the battery) the regulator in the alt may be bad. You state that the #1 terminal is connected to ignition. It should be passing through a marker bulb (NOT LED) on its way to the key. Or a 10 ohm resistor, or a diode with the band toward the alternator. Without this device in the wire (series) the engine will continue to run even with the key shut off. This light/resistor/diode device acts like an idiot light, and must be there. Jim
