As you describe the problem, the reason is unstable load handling.
This means that the fuel or air is not enough.

When begin to be unsteady:

  1. If smoke comes out of muffler - the input air is not sufficient. Try to clean or change air filter (cleaner).
  2. If no smoke, the fuel is not enough. The reason may be the mechanical governor, or the fuel supply to it, fuel filter/strainer etc.

Output of generator is lower voltage than it should be usually 440v now 395v? reasons?


possible that the rpm of the gen set is lower than normal
there is an adjustment screw that adjusts the spring tension for the governor and it can be adjusted to bring the voltage back to normal
Note here--- if you run the set with a load of around 1/2 capacity set the voltage to on the 440 volts
if you run it at near capacity set it above voltage (445) because as it comes under load the rpms drop and the voltage comes back to normal

The coleman voltage generator for 250 kva gen set


Well I assume that this generator is NOT three Phase, and delivering 440 Volts? in that case, that reading is what is called and "Open Circuit" reading, with a full load, that reading will/should come down to the nominal voltage of 250 V (+/- 10%) This generator is a 250 V AC unit? If this is so then it is operating correctly? It is 5kw UNIT. using a digital multimeter due to it's large input impedance it will often give erroneous readings if NOT loaded down with the correct.any. load.?

Gardian Generator transfers while doing whisper test


How does it do for RPM's with light load? Try turning off some load so when it transfers, you can see if you're overloading it. To much load could bring down the speed drastically. If it holds speed with 3/4 load, that's probably the problem. If not, try half load. You need to match the load watts to the Gen KW.

Yamaha ef1000 will only idle and produce 12 vac


Hi, I have the same generator and I pull the load and it is fine. The engine RPM is controlled by the 
governor. The voltage will not come up until the RPM is at full. First see what the RPM problem is and then check the voltage. Open the cover and look to see if the carb linkage is hooked up , if it is you mite have carb problem and address that first. Hope that helps.

Low voltage


Most generators use a flyball type governor within the engine to control rpm; also there is a voltage regulator that tries to maintain voltage at about 115v. The voltage regulator varies the voltage to the armature increasing /adjusting magnetic force. Use a meter with htz or freq setting to adjust engine governor to 60 cycles. When the generator is producing 60 cycles, the engine should be turning 3600 rpm, max power range. At 3600 rpm the voltage should be 115 to 120 volts. Loading the generator will cause governor to try to maintain 3600 rpm. Check engine manual for proper adjustment of gonvernor and linkage. The governor mech should last the life of the engine, however governor system does wear out. Expensive repair. enjoy
