Title: The voltage is correct at no load while too low at load - alternator
Author: tongli motor  Time: 2012/7/28
Let the alternator run at no load, check the voltage between “E+” and “E-” on AVR.
1. The direct current voltage between “E+” and “E-” SHUNT/PMG < 10V, Check the rev (or LAN configuration too high)
2. The direct current voltage between “E+” and “E-” SHUNT/PMG >15V.
Rotating diode failure.
Main rotor short circuit, check resistance.
Exciter armature failure, check resistance.
