I have a Kohler 7KW gasoline unit. The speed adjustment is maxed out but she will only reach 113-115 volts, wfo and fully loaded. I feel that there must be either a weak spring, a supporting/contributing adjustment that is off or "something" else that needs addressing. Fuel screws are adjusted per manual. Gov works fine and the voltage is fine but I hate to see any adjustment at it's full range.

Comments, suggestions? (Yes Dale, it works, that's why I just gotta fix it!) :-)

Have you checked the frequency? I would be more concerned about frequency than voltage.

Did you check to makes sure that both ends of your male/male cord were plugged in??? Grin

Ha! Yep, both ends are plugged in. :-)

Bill, I was under the impression that the speed, voltage and frequency were fixed parameters. i.e. if the speed is low, the freq and voltage are correspondingly low. Did not have a freq meter and used the little plug-in receptacle meter as my guide. I knew the thing was 5V off (or so I thought). I just connected the digital volt meter and WHAT! The plug-in meter was 8-plus volts low. So, my gen voltage is actually pretty good.

I will obtain a freq meter and verify that parameter asap.

RPM and frequency are locked together. Voltage depends on flux density, field excitation, loads, phase of the moon, etc.

For a meter, look at Kill a watt at radio shack.

I hear ya bill. I just assumed that "..and then a miracle occurs"....in the gen unit was the operative mode.

Thanks for the tip on the meter. If our Uncle Sam doesn't have one I can check out on an overnight authorization, I'll go to The Shack.

ata boy ron, let us tax payers pay to fix a Barth. Sounds like a good idea though. I bet the Uncle has GOOD equipment too. Keep us posted too. Dale

When I used to work(four letter word) in the engine room of the fire boat in Seattle I always check the HZ and if it was low I would have to raise the RPM of the gen set to bring it up the the correct cycles. If it was too high I'b lower the RPM's. Dennis

hi use tac 1800 rpm 60 c 120 v put small load test hop this helps carl
