SOURCE: My powermate portable generator runs but no AC

Hi. Lets cut to the chase here... Check for 5 - 7 DC volts on the brush block wires with the unit running. No voltage = bad VR Voltage = possible bad brush block or... that you may need to flash the generator field. I know you asked for a service manual but I am telling you these simple steps will save lots of time money and grief.

If you disconnect ONE wire off the brush block you should be able to read resistance of the armature. If you can not read that resistance then the brush block is probably not contacting the slip ring. If you do read resistance across the brush block with one wire disconnected then it is time to try a field flashing.

The manual calls for applying 6 VDC to the brush block wires engine running to flash the generator field . Over my many years of working on generators I have found that you can use an electric drill plugged into the the power outlet and the output power switch ON. You then turn the drill as fast as you can by hand...(YOU MUST PULL THE DRILL TRIGGER at the same time.) It is a little work to do this but it works well. You must be careful though because once the field does flash the drill is going to run... i.e don't grip the drill chuck to tight or at least LET GO of the TRIGGER when it takes off! What ever you do avoid using a rag on the drill chuck while turning it.

Give all of the above a try first and if we really have to, I will dig out the manual and copy and paste text only :( pictures I will have to send you links for.

Thanks for choosing FixYa.
