My 87FC35 has a 8.0 kW genset. I am getting low voltage out of it
(around 95 volts). On my last onan genset (77 GMC - carbed gas),
this was a common problem and was simply corrected by increasing
RPMs. (If this is the fix, how do I adjust idle speed? This fuel
injection isn't as intuitive for me as I've been a carburetor guy.)
I found an installation manual for the genset and it says to adjust
some "taps" on a transformer regulator. It also says "output
frequency is determined by engine speed and normally does not
require adjustment." I'm not exactly sure what it means by "output
frequency". Is that voltage??
Is this problem more complicated than adjusting the RPMs? Maybe I
don't have one of the Onan manuals..?? I have a parts manual and an
installation manual.
I have searched the forums and did not find a post that seemed to
address my situation. Let me know if I missed it.
Thanks in advance,
Alan Johnson
