Question about Coleman Powermate Portable Generator PM0435003
At 3600 rpm generator is supposed to produce 120 volts 60 Hz but my unit produces 133 volts 60 Hz. How do I correct this issue?
You cannot, speed is propertional to voltage on these, as they have capacitor voltage regulation. Do not use this for powering home appliances, it is common to see this design and not a problem. If you add load and it will decrease but so will the frequency

There is a electronic module that senses load current that pulls the throttle up for high RPM. Fine the module and look it over, you may need to replace it.

First check with the
dealer and see if it is still under warranty. If it is not, make sure nothing
is blocking the air flow around where the control modules are located. This
could cause the voltage regulator and other electronic parts to overheat. Next
check the brushes and make sure they are free of any dust or build up preventing
them from making contact.
If everything is OK the next thing I would do is change the voltage regulator.

Well I assume that this generator is NOT three Phase, and delivering 440 Volts? in that case, that reading is what is called and "Open Circuit" reading, with a full load, that reading will/should come down to the nominal voltage of 250 V (+/- 10%) This generator is a 250 V AC unit? If this is so then it is operating correctly? It is 5kw UNIT. using a digital multimeter due to it's large input impedance it will often give erroneous readings if NOT loaded down with the correct.any. load.?
