have several question about diesel alternator. First of all i want build micro hydro system using diesel alternator. That means i just take the alternator and using water to rotate the turbine and the alternator will produce the power. Do you think this system is possible to do? Before this i use the car alternator, and the problem is before alternator connected to the battery i get about 3000 RPM, but when i connect the alternator to the battery and field current occur, the RPM dropped to 500 RPM. So the alternator can’t produce the current. So i want try using diesel alternator. Since we know diesel alternator power output in AC, so no field current needed. If i get around 3000 RPM, whether diesel alternator produce the power? Or it same with car alternator.
