I have a Generac model sd25/16471, serial no. 0774976

Customer Question
I have a Generac...

I have a Generac model sd25/16471, serial no.(###) ###-####diesel. Engine runs fine and was producing electricity. It has stopped making electricity. I bought it used and never got a manual and don't have schematics.

Mechanic's Assistant: Can you guesstimate how old the engine is? And has it done anything like this in the past?

All that I know is that it is old enough that when I type in the model or serisl no. on the Generac website it does not recognize either.

Mechanic's Assistant: Do you plan on doing the work yourself?

I plan on doing the work myself. My first thought is the exciter or diode set, but it's hard to find the test points without the schematic.

Mechanic's Assistant: Anything else we should know to help you best?

This is a 3 phase unit.

Customer reply replied 11 months ago
Are you referring to error codes? If so, this generator does not show any codes. There are only engine indicator lights, which are all showing normal with the engine running, an ammeter, voltmeter, and frequency meter. The frequency meter shows 60 hertz, and the ammeter and voltmeters show 0 on all phases.
