Yamaha EF5000 not producing power

Runs fine, fuses are fine, not sure how to check the breakers. It was producing electricity just 3 days ago before cold weather hit with light drizzle. Need help fast! Got a job to finish.

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...

I have the same unit and same problem.
I have lost my owners manual. Did you figure out what needs to be done to correct the no output issue.

What could be causing my golf cart to lose power? In the morning, it barely goes up the hills. It seems to run normally at night, but when I hit the gas pedal the lights go completely out.


Have the battery checked. Especially make sure they do a shunt regulator test on the cells. Sounds light a shorted cell in the battery.

Dewalt dg6000 runs but will not produce electricity


High and Low Temperature Operation
Air temperature affects generator output. Output drops 1% for each
If the engine does not start:
1. Check the fuel tank for sufficient fuel. Refill with fresh gasoline if necessary.
2. Check the engine oil. Fill to the upper limit with fresh oil.
3. Ensure that the fuel petcock is open. The fuel petcock is open when the lever is perpendi-
cular to the ground (straight up and
.
If there is no power to the receptacles:
1. Turn the circuit breaker switches off and disconnect all electrical loads from the generator.
2. Turn the circuit breakers on and test the GFCI's by following the procedures in this manual
on page 1.
3. Place the voltage selector to the 120 Volt only positions (unless you are using a tool that
requires 240 Volts).
4. Turn the idle control switch off.
5. Turn the circuit breaker(s) off and reconnect the electrical loads. Be sure that the plugs are
securely connected to the receptacles.
6. Turn the circuit breaker(s) on.
7. If there is still no power at the receptacles, take the generator to an authorized D
service center. To locate a D
WALT service center nearest to you, call 1-800-4-D

Husky 5000 watt generator quit producing power.


You could have a bad circuit breaker button. Replace that and see what happens.

Check the thermostat and make sure the fan switch is set on "Auto". If it is set on "ON" the blower will run constantly.

My car doesnt want to start up right away in the morning. Almost like its really cold out and it takes it a min. The rest of the day its fine runs great. Any ideas?


Reason 1 - Gasoline, like any other liquid, evaporates less when it is cold.You have seen this -- if you pour water onto a hot sidewalk it will evaporate a lot faster than it will from a cooler place like a shady sidewalk. When it gets really cold, gasoline evaporates slowly so it is harder to burn it (the gasoline must be vaporized to burn). Sometimes you will see people spray ether into their engines in cold weather to help them start -- ether evaporates better than gasoline in cold weather.

Reason 2 - Oil gets a lot thicker in cold weather. You probably know that cold pancake syrup or honey from the refrigator is a lot thicker than hot syrup or honey. Oil does the same thing. So when you try to start a cold engine, the engine has to push around the cold, gooey oil and that makes it harder for the engine to spin. In really cold places people must use synthetic motor oils because these oils stay liquid in cold temperatures.


Re ason 3 - Batteries have problems in cold weather, too. A battery is a can full of chemicals that produce electrons The chemical reactions inside of batteries take place more slowly when the battery is cold, so the battery produces fewer electrons. The starter motor therefore has less energy to work with when it tries to start the engine, and this causes the engine to crank slowly.

All three of these problems can make it impossible to start an engine in really cold weather. People either keep their cars in heated garages or use "block heaters" to get around these problems. A block heater is a little electric heater that you plug into the wall to keep the engine warm.
i hope it was convince answers

My unit was working fine until 3 days ago when the breaker tripped, I reset the breaker and worked fine for a day then tripped again when it tripped both the ac breaker andthe main in the trailer as well...


High amp draw can be caused by a few different things, so first check that incoming voltage to trailer is sufficient. (115 volts) Not unusual for some parks to install more hydro hook-ups on a feed line, and when all are up and running, your incoming voltage could be decreased. If your o.k. that way, then I'd start looking at the compressor circuit of your ac, in particular, the compressor start-up capacitor. The capacitor basically stores electricity and boosts it to higher voltage for compressor and fan start-ups to reduce current draw that will trip the breaker. Please have a knowledgeable electrician, or RV tech check this for you, as a capacitor can give a real good high voltage (possible fatal) shock, even when power is off to unit. I also suspect that the start relay has shorted (welded) itself due to high amp draw situation, and that is reason it comes on by itself.

B93-366 Indoor Unit Ours is mounted on the wall in a new room addition (3 years ago). Has worked fine. Used it with remote control a few days ago. It worked fine. Turned it off with remote control. next...


You will have to remove the front panel and check the fuse to make sure that it did not pop. Also check your breaker switch to make sure that your breaker did not pop. Those can be your really only two issues

I get a warning message, "HIGH ENGINE TEMPERATURE-STOP ENGINE" from our 2002 S60 Volvo upon starting. The check engine light also comes on. The electric fan come on and runs for approx. 2-3 minutes....


Mine is doing the same thing. I have taken it to the shop and the mechanic can't find anything wrong with it. When he resets the diagnostic, the car runs fine for a few days then it happens again. I'm thinking it is something due to the cold temps here in NW Iowa. It is obviously not a cold weather car!

My generator is not producing power runs fine does not make power


Could be several problems on the gen set itself. Check to see if there is a surge protection breaker or fuse, depending on age. Make sure all connecting wires are secure and switches are not set to 240v instead of 120v if you are trying to use outlets.
