Does anyone know how to adjust the dc output voltage on a Millers Fall generator

HI
Very easy you will need a meter which can read to 10 amps DC @ 12V( fairly common except for the real cheapies )
start the generator and hook the meter between the positive terminal of the battery and the generator positive lead, hook the neg. lead from the generator to the battery as normal the battery is best half charged as a full battery will not accept a charge as easily (and you never charge a full battery anyway).
now take an amp reading about 5-6 amps is ok but if only 1.5-2 amps as i've found most are off the shelf adjust as follows
Locate the throttle screw on the side of the carby ( this screw operates the butterfly in the carby and should operate on a cam type arrangement with spring return) it is located in the space between the fuel tap and main motor housing approx 60 -70 mm in you may have 2 screws to pick from it is usually the one closest the motor(but there are a few different types)adjust this screw in until the amps come upto 5 - 6 this is ok if you go much higher you will start to affect the 240v frequercy no real problem as you should not be running frequercy sensitive equipment off this typy of generator anyway
I think the factory set the 240 frequence and dont worry about the 12v because they vary a lot
best of luck Kev
ps if you need more just ask.

Thanks Kev
What we are trying to do is adjust the voltage not the amps. Any clues with this.
