SOURCE: generator runs producing no power

Hi, remove the electric control panel & check the wiring as sometimes we have seen the wires coming off the voltage change over switches.
Also some of these units you can check the connections in the rear of the alternator & if it has brushes that they are not stuck.
Another problem we have had is the trip switches have went faulty but still switch operates ok, they need to be checked with a probe type tester for conductivety.

SOURCE: generator runs, but produces no power

If it's still under warranty take it back to the retailer and tell them it quit working - don't offer any other information.

If you must fix the E/G yourself - On the generator there's a cover on the back; take the cover off so that the back of the windings are exposed. You should see 4 to 6 diodes mounted to the rotor and stator...those diodes are most likely burned out because of temperature failure, due to overload. You have to take them out to isolate them...they should read .6 Ohms one way; reverse the leads and they slhould read about 1.2 Ohms. If there shorted you'll read 0 Ohms and open infinety.

Anyway, replace those diodes and you should re-establish your field winding voltage which develops you A/C output.

Good Luck,
Mike...

SOURCE: 5500 generator stopped producing eletric after

First check with the dealer and see if it is still under warranty. If it is not, make sure nothing is blocking the air flow around where the control modules are located. This could cause the voltage regulator and other electronic parts to overheat. Next check the brushes and make sure they are free of any dust or build up preventing them from making contact.

If everything is OK the next thing I would do is change the voltage regulator.

Ef2600 yamaha generator will run fine for a day Go to start it the next day it won't start


If the fuel tank is below the carb, check for a check valve in the fuel line not seating. You can verify by shooting a bit of starting fluid in the breather. If it starts and then hesitates a bit and then runs, it means that the engine speed was adequate to suck fuel back up into the line to the carb.

Engine is running rich, spark plug is black, spark arrestor is black, after only 2 tanks, do they have smaller jets for this carb


you need to alter the fuel mix. there is a fuel mix screw on the side of the carb. screw in for less fuel. then check on ldel loads on spark plug... then test on full load then check spark plug again. dont mix up the idle screw with the mix screw. should have a white film on idle speed and a slight red colour or full load. run for 10min at a time then check.

Generator has voltage drop, why?


Most of the small portable generators will depend on the engine speed to regulate the voltage. If the motor is at the correct speed you are getting 120 volts 60 hertz, if not it will read lower like 115 volts 55 hertz or so. This can be fixed by adjusting the governor, or idle speed needle.

Can you help me? I have generator yamaha ef 2600. Generator normally running about 3 minutes then rpm comes unsteady and gen stops. Moreover at load 2kW gen immediatly works unsteady and stops. Without...


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.
