What to check when the Kipor 4,5kw generator slows down once you connect some things like iron?

SOURCE: coleman 1850 sport, no/ low generator output

Hi,
The engine should run at 3750 rpm at no load. If that's OK then you may need to troubleshoot the capacitor inside the end of the generator opposite the rope. Since the thing has been stored for some time you may just need to flash the field of the generator to restore the residual magnetism in the rotor. The easiest way to do this is thru the 110 outlet but it's a little dangerous. Plug an old lamp cord into the outlet, start the generator, and momentarily connect a 9 volt dry cell to the wires, then shut the generator down and see if there is 110 when you restart it.
Regards,
Carl

Both the Hz and the voltage will be wrong if the engine speed is low. You need to use either a DMM with a HZ function to set the engine speed so that you get 61.5 Hz at no load, or use a tachometer to set the no load speed to 3750 rpm.

chek brushes...if they seemed ok then replace AVR card

Those voltage readings MAY be normal.

The AC waveform may cause your meter to read inaccurately. You would need to use a TRUE RMS meter to accurately read the voltage.

The siple meters actually read the AVERAGE voltage and then are calibrated to mulltiply it by the "form factor" for a sine wave. OFTEN these generators don't produce a clean sine wave. A square-ish wave will read higher on the garden variety meters.

Compare the brightness of a lamp comparing to when run on your utility.

The frequency depends on engine speed ... yours is running a bit fast...check it under at least half load and if off, adjust the govenor slightly.
