Your RPM's are too high. There is no voltage regulator in coleman generators (generator is actually made by generac) and is 100% dependent on engine speed. There is a screw under the tank when your looking in from the recoil side. It controls the governor arm. Screw it in and it incresses the rpm, out decrease. Plug something in that draws a decent load while setting the rpms since you want it to put out 120 and 240 underload. Your idle voltage does not matter.

To flash fields the genset has to have rings and brushes. The ring towards the bearing or towards you is positive and the back ring is negative. The rings and brushes are on the rotor, which is the part that spins on the generator end. Place a volt meter on the outlet, start the genset, with a 12V battery apply the positive to the front ring and the negative to the back ring. The voltage should climb up to about 50 - 100Volts or more. If this happens then you will need a Voltage regulator. If voltage does not climb up, then check the rings and brushes. Make sure the brushes have a good length and that they touch the rings and make sure the rings have a shiny copper color to them, if they're black clean them with emory cloth until there is a nice copper color and try flashing the gen again. If nothing happens then you need a new generator end or new generator, which ever you prefer. Make sure to use rubber gloves when flashing and look out for rotating parts.

The control board that senses load (current) is not working.It should drop to low with no output current. (nothing running)

SOURCE: no output from my generator
Check the capacitor in the generator head. Will onpen or short cause loss of excitation voltage. Just checked my GENERAC ( no output) and sure enough the cap is shorted.
