8.5 kw rmy Kohler generator, have not used in over a year. engine runs fine but will not put out any 110 voltage at all.
Check the rotor slip rings for tarnish as it has sat.
If they are clean, the rotor may have lost it's magnetism and may need flashing (putting DC power directly on it for approx 3 seconds) with brush wires disconencted POLARITY IS CRITICAL

Your gas pressure is too low and you may not have a large enough supply pipe. You need at least 10 inches of water column with the engine running to operate an LP vapor fueled engine. Because the engine is starving for fuel, its governor opens the throttle to WOT (so it goes to high revs) but there isn't any fuel to make horsepower with so the output voltage falls and the undervoltage alarm trips.

I have a Ford LGT with a 14 hp Kohler K321AS engine. Go to Kohler.com and download the service manual for the K321 engine. The manual covers all of the K type engines and gives diagrams and details of all the different types of ignition and electrical systems. It is free. JS

sounds like a relay should be latching one it has started
Testimonial: "Thanks. Will take your advise to my electronic wiz-kid friend who has the generator regulator, & is going to run tests. Will let you know the outcome."

I have fixed Dozens of generators and around 70-80% of starting- none running problems are due to either A) Debris soil dust or Water in the Carb (don't ask me where it comes from but it gets through or B) Jets blocked with same or just Electrolytic Crud, dissimilar metals Brass Jet in Allot Carb etc. First step drain tank & carburettor bowl (screw or bolt in bottom usually, run a needle or similar though the main jet (up in centre in Honda type designs) when sure all is clear, fit a $1-$2 small paper in-line fuel filter and try again. The standard filters are too coarse and let in fine dust-rust all the time, hope this helps always works for me, Good Luck from England!
