I have a customer that had installed a 12KW standby 6 yrs ago. However the contractor never completed the job. All I had to do was connect to the outside connection box. The unit started on power loss simulation but will not generate power. I am only getting 18 VAC L-L, and 9 VAC L-N.
Has anyone ever encountered this situation? I am leaning towards 1) brushes stuck - due to 6 yrs of no use
or 2) voltage regulator.
Thanks for any input.
