Northstar generator w/GX620 engine shutting down
I been using gen for over 20 years on my farm as backup for my solar system and one issue the haeds...many users forget or no one tells them that they need to adjust the heads after every 40-50- hours and any changes in the setting will not allow the grn to start ot it will run for a few seconds than die...look for the exact seerting of the in and out and check tghem and see if that help...good luck. remmber in winter you need low grade oil not high or use synthatic better.

Generator had been running for 3 hours with a/c and refrigerator and lights (on concession trailer)when we experienced a loss
the unit has gone into over load
The total power requirement has exceed the output of the generator
for example if the generator is a 2.500 kw or kva then it will generate well at 1.8 kva or kw but it will not run forever at 2.5 kva -kw
When a ac is running the power requirement will be constant on the generator and with the fridge as well then the load will be at the maximum out put of the unit.
when the fridge starts again the extra load will exceed the max out put of the generator and it will slow down ( lights dimming ) and eventually go into overload mode
have an accredited electrician calculate your maximum load requirement for an external power supply and then get a unit that is at least 15.. kva kw better that required
generally fridges use 1000watts , ac conditions will draw over 3000watts and any thing else adds up . I am guessing that your generator is only 2500 unit

I have a northstar generator that runs but not putting out any power
If it has sat, it may have lost it's rotor residual magnetism. Disconnect the rotor field wires at the AVR or on the exciter/brushes. Note they are polaroty sensitive. Connect a 12V battery to F+ and F- (note polarity) and momentarilly power from the battery for a few seconds. DO NOT forget to disconnect the rotor/exciter field wires first or the voltage regulator will be damaged. If it hasn't sat check voltage regulator, rotor resistance, and stator resistance, and for shorts to ground.
