The primary thing to look at is the belt tension, especially if you are noticing loss of power in precipitation. Consult the aircraft or engine service maintenance manuals for precise instructions. If the tension is proper, make sure the aircraft wiring is correct. Check that the field terminals are not loose at the ground through the regulator or at airframe. The next thing to check is to make sure you have power to the field. With the engine not running and the system turned on you should have about battery voltage at the field. If you have voltage at the field and the voltage regulator is suspect.
