I HAVE A 2001 NATIONAL MARLIN '39 with a quiet pack 75d generac
generator problem. I am having running the coach a/c with the gen. AT
idle the gen. output is 124vac and 63hz,but as the a/c compressor trys
to start the voltage drops from between 90&65 vacand55&45 hz, before the
genny dies. Replaced voltage reg. ,NO HELP.

My Diesel Generac powers TWO AC's running at the same time.......no problem. You definitely have a problem somewhere. I recommend professional help. Rook

I forgot to ask....does your AC's run normal on shore power? Rook

Thank you for your response ROOK, yes they both work on shore power

Sounds like a governor issue or fuel restriction (filter).

I'll check the fuel filter thanks
