generator running and producing no power output little help please

[reynoldston]

Have you tried to clean the commutator with a commutator cleaner stick?

Its something I have to do with my small Honda generator every so often after it sits for a long period of time for some reason. The cleaner stick I use looks like a large pencil eraser on a stick made for this, in which I bought from Granger.

The easiest way to confirm if it is the voltage regulator is to first disconnect the regulator form the system. remove it and set it on the bench. you should have 3 heavy wires that are your main power windings be careful as these could be hot. make sure the brush wires are disconnected. hook up jumper wires to the brushes. start the unit and hook a battery to the brushes. now check the power output between the 3 larger wires. if the AC voltage is over 120/240 (or the UK equivalent) the generator is fine. it is the voltage regulator that is bad.

********please note, do not leave the battery on for very long. the whole test should only take about 30 seconds*****************
