Question about Power Generators

Generator runs, but does not generate electricity

I have a Valsi GV75MG1300TV 7500 Watt generator that I purchased and used after Hurricane Katrina. The motor still runs fine and I start it every few months, but when I needed power after Hurricane Gustav, it would not generate electricity. The Voltmeter on the Generator is not registering anything. It will occasionally bump off of zero, but not for any amount of time. I checked connections and flipped breakers, but have not gotten anything out of it. Reading the manual seems to indicate that a capicator or diode coule be broken?? I have also heard others say that sometimes generators need to be reset ot "Tickled". Please help. Thanks.

    I have the same problem with my Coleman 7500 Vertex Professional vertical gas generator. Engine runs and breakers don't seem tripped, but no juice. Perhaps a blown capacitor?

    Have checked continuity in all coils. Checked and replaced the cap. checked the diode. All ok. have remagnitised. Still not generating any power.

Reset / tickled? There are resistors and diodes in the end of the alternators rotor (the bit in the middle that spins) If these look ok visually then change the capacitor which is a barrel shaped object usually with 4 prongs on the end. Without a capacitor the genset will not produce a voltage.

You can apply 12 volts to the output for a couple seconds, with the engine OFF, and it will bring back the magnetic field in the armature. If that didn't fix it, you have to rotate the shaft 180 degrees and apply the 12v to it again with the same polarity as you did the first time for a couple seconds, and it should work this time. Easy fix, done it many times.

Tuching small 9volt battary to brush leeds when off will recharge small exsiter

Yes on the 7500 series you sometimes lose the magnetic field - to correct this buy a 6 volt flashlight battery - with the unit off induce battery voltage to the brushes -then try to run - if it doesnt work try again . it may just be an exciter prob -

Generator runs great but produces no power


On Thursday last week I had 220 amp outlet being used and a 110 amp outlet being and overloaded the generator. It turned out to be the reset breakers failed to trip and blew the capacitor. The reset breakers I would suggest replacement after 7 years very easy to do on a 5500 Valsi generator 2010 model still running and now producing electric. And of course use only regular gas non Ethanol.

Possibly the needle and seat valve or check for a cloggeg air filter or a tear or hole it the carb body.

We have a Valsi 5500 watt generator that isn't putting enough voltage out to run everything in out small travel trailer. It runs the lights but doesnt push out enough voltage to carry the A/C, microwave,...


How long have you had this generator?
Has the generator worked on all of these loads before?
Model 5500 is a 5500 Watt generator which could easily be 5500 watts (Peak) and not continuous.

Your AC is an inductive load.
Your lights are resistive loads

An inductive load can cause issues when starting due to an increased current demand at start up that some generators cringe under. Do the lights flicker or are they stable? I'd say your diodes on your stator are working if you have light stability but you haven't provided nearly enough information for a detailed solution.

I'm sure you have enough voltage but you aren't getting enough current to run specific loads. How many watts is your AC? How many watts for your microwave? Both of these units demand a great deal of energy to run and when you place too much demand on your generator, it will choke it out and eventually, will cause damage to the generator. You may consider getting a beefier generator with a greater amount of wattage output.


Seeing these specs online and noting what you are trying to run, you have an undersized generator and need to get one that can produce a greater amount of running wattage (as well as peak wattage).

How long will it run on a full tank of gas????


Hello. W/D here.
You've posed a fine question, as it has several answers. We used one of these during Hurricane Katrina.
1. At idle, you can expect about 6 hours.
2. Fully loaded, you can expect to refuel it at about 4 hours without the tank being empty.

Your actual time will vary with the demand placed on the generator, but these times are best as I recall.
Hope that this was of some small help, --W/D--

Have a VALSI 5500 watt generator that works fine but the tank has rusted out and I cant find where to purchase a new one. Can you help me find where to purchase this tank


We had problums with this one also. If you absolutely cant find a tank repair it.

A motorcycle shop in your area has no doubt had plenty failed tanks to repair. and then have it plastic coated on the inside.

The problems stem from the use of fuel with ethanol it attracts watter and dosed not work well in a gen set that spends lots of time setting.

Begin using fuel with a fuel stabiliser and keep it full, Air also has water in it.

VALSI 5,500 WATT GENERATOR WILL NOT START


All generators need to be run once a month. All things from the tank to the and including the carb will get gummed up with dried out fuel. I have a whole house generator and a 5500 watt gen set on my motor home. I keep fresh fuel in the stand alone house generator in California in case of a bad earthquake. I drain the gas after every run and keep all vehicles full of fuel just in case. Run gen sets at least once a month or pay pay pay!!

Generator will not generate electricity.


I assume it is a hand start genset. The most common problem if it has been sat for a while is rust on the ignition timing flywheel. If you take the pullcord housing off (recoil) then you will see a big flywheel with what can only be described as a big forked prong with a couple of wires on it. This flywheel should be stainless steel and rusts when sat around for a while without use. Its job is to complete the circuit to the spark plug every time the flywheel passes the forked prong at a given spot on the flywheel, the faster the wheel turns the faster the spark hence the engine runs quicker. Clean the rust off with a releasing agent (wd 40) hey presto!!!!!!!!!!!
