Hi all,
After working out bugs on my new genset I found that I too had the undervoltage, Caused by the blown fuse next to the regulator, replaced the fuse and found that the freq is good and adjustable but the voltage is at a steady 200 with no adjustment. (And now stops with over voltage) The rheostat for the voltage works so I suspect my regulator is bad as well. I am going to pull it tomorrow and test the components. My question is, why do these seem to be a common failure? Is it user error? Or someone testing the genset not knowing what they are doing? Maybe someone hitting a switch at the wrong time? My experience with most military equipment is it is overbuilt and over spec'd material wise so it surprises me a little that these seem to fail so often. I design and test things for a living so I do know no matter how idiot proof you try to make it, there is always a bigger idiot! Once I fix it I hope to keep it fixed!
