      And each electric heater only draws 10-11 amps. So the gennie will run two heaters all day long, but a third one slightly exceeds the 20 breaker on that leg and off she goes.
      Correct. Since the load is not greatly over a leg's current, it will take a little while for the breaker to trip.

        If the engine does not display any grunt or slowing before the breaker goes I would suggest the governor is not opening the throttle to pick up the extra power needed for the extra load. I have a 2kva which I use for site lighting, and you can hear the engine tone change every time you add load to it. It slows a little then the governor picks it up and increases the power (opens the throttle) Check the governor is not stuck.

          The "tone" of the engines changes for a second, but it never sags or sounds like it's lugging. RPMs and voltage are quite stable, you know, for a generator. governor working properly.

          Of course, the engineers try to match the powerplant to the alternator, so you're not wasting horsepower with an overly large engine that never works hard, and neither are you wasting alterator power with a big oversized unit that the engine can't push to full capacity.

          I suspect the engine could do more, but we'll never know since the alternator poops out first.

            FYI- generally you can't use the 12v output at the same time as the AC output. The breaker(s) will trip.

              Here's how we tested my 10Kw VW Diesel-powered genset:



              That wire has red insulation, it's not red-hot. Note that the assembly is hung from 2 insulating boards for safety. There's a disconnect switch, voltmeter, and clamp-on ammeter in the pic, along with a photo-electric tachometer to check the speed droop.

                Excellent! How did you achieve governor control of the throttle?

                finest regards

                  Doug,
                  Here's the entire story: http://www.oldengine.org/members/jdu...t/sep13_01.jpg

                  And a pic of the governor:



                  and the linkage:



                  I removed the return spring from the pump speed control lever, and later added a switch to contact that Heim joint in the middle of the shot above. It's actuated if the speed control is wide-open, as it would be if the belt on the governor broke. The oil pressure switch bypass button also bypasses this switch during startup.

                  I forgot to mention, in case you don't know, those stove heating elements are 240 volt, so there's no imbalance.
