Dear Friend:
There is a Switch transistor to power on -off the hi voltaje for lights. Check 15V from power source go to this transistor colector, Using soldering Iron, make a juntion between colector and emiter, to short 15V to Hi voltaje power. I´m fixing 10 monitor the same trouble. I will remove a liter transistor.
Late I will post here the driver transistor number, and the replace number transistor I will use.
Pictures , etc. Best Regard

That sounds just about right, if the relay contacts get welded together it sometimes takes out the driver on the printed circuit board. As you found out, 12vdc from 23 to 194 makes the transfer switch move to the Generator position, relay not energized makes the ATS move to the Normal position.

You can make a nice test function by installing a 10 amp contact switch in series with either the N1 or N2 terminals. When the switch is open the generator thinks the Normal power has failed.

Carl

Make sure that the throttle linkage is all there and not damaged/misadjusted, then get a manometer and check your inlet gas pressure. Gas pressure should be 8 inches of water column and stay there running or not.

Check the Ground Fault Indicator circuit breaker for triping, and look for the high limit on generator. Reset the main breaker by triping it full right and then back. Vitally

SOURCE: overload, switch off

I had the same problem, in that the receiver would automatically shut down displaying the "overload" message. I checked the 5 fuses inside, as well as ensured that the fan was working. I was using six 4ohm speakers + subwoofer. All the speakers other than the rear center channel and subwoofer were ceiling mounted in the room.

However, I decided to check the overall impediences of each speaker line to ensure that there wasn't an issue with the speakers. It turns out that the net imediances of the four corner speakers and the front center speaker were 5.7ohms because of resistance in the long lengths of speaker wire I had. However, the impediance of the rear center speaker was only 4.7ohm -- because the speaker line was much shorter.

Thus, the quick solution: ensure that all the speaker line lenghts are the same, (to ensure that the overall imediances of all the speakers are the same). Once I did that, the receiver started working beautifully -- full loudness surround sound working fantastic.

Yamaha 2400IS Generator goes to overload when ie: 240 volt plugged in, or 700 watt angle grinder plugged in.


No idea but somebody else will probably come along with a better idea then mine, seems a lot of these generators have this thing installed on them (Has $25 hard start kit). Not sure what it does or how it works. Strangely enough you said you use it for 240 volt. Looked at the picture and didn't see a 240 volt connection.
If you are using the what look like the 120 volt circuits you can't over load the unit. Maximum current draw will cause it to go into protection mode and shut down the power load. The following is an exert from the owners manual which I got from Yamaha's site. Link at the end of this post.

Hope this helps

Overload indicator light
The overload indicator light
1
comes on when an over-
load of a connected electrical device is detected, the
inverter control unit overheats, or the AC output voltage
rises. The electronic breaker will then activate, stopping
power generation in order to protect the generator and
any connected electric devices. The AC pilot light
(green) will go off and the overload indicator light (red)
will stay on, but the engine will not stop running.
When the overload indicator light comes on and power
generation stops, proceed as follows:
1. Turn off any connected electric devices and stop
the engine.
2. Reduce the total wattage of connected electric
devices within the application range.
3. Check for blockages in the cooling air inlet and
around the control unit. If any blockages are found,
remove.
4. After checking, restart the engine.

Generator had been running for 3 hours with a/c and refrigerator and lights (on concession trailer)when we experienced a loss


the unit has gone into over load
The total power requirement has exceed the output of the generator
for example if the generator is a 2.500 kw or kva then it will generate well at 1.8 kva or kw but it will not run forever at 2.5 kva -kw
When a ac is running the power requirement will be constant on the generator and with the fridge as well then the load will be at the maximum out put of the unit.
when the fridge starts again the extra load will exceed the max out put of the generator and it will slow down ( lights dimming ) and eventually go into overload mode
have an accredited electrician calculate your maximum load requirement for an external power supply and then get a unit that is at least 15.. kva kw better that required
generally fridges use 1000watts , ac conditions will draw over 3000watts and any thing else adds up . I am guessing that your generator is only 2500 unit

Wolf 5000kva generator


Locate where the choke lever is for your generator (under the petrol tank), you ought to notice a star headed shaped screw connected to the governor shaft (if you bend and look closely further beyond the choke lever; still under the petrol tank) which is linked to the carburettor housing/assembly. You need to increase/turn clockwise (using a star screwdriver) on this screw.

Your generator engine sound will change/high a bit because the engine speed will increase.

Reconnect your 1800w chop saw (load) and see if your generator can "effortlessly" accommodate it without shutting down otherwise, increae the turns on this adjustment screw attached to the governor shaft till your generator operates/stabilizes with the load (1800w) connected

Overload light eu3000 comes on with trailer roof ac never did before


The battery is really only there for the electric start. Put a digital volt meter on it while running it under the load of the AC unit. Or if it goes off on the overload with the AC unit, try a variable load like an electric heater or two that you can switch on in steps. Most space heaters or hair dryers have a 1000w, 1250w 1500w so you can increase the load. Watch what the voltage does. If at 1500-2500 watt load the voltage starts to drop drastically, say from 125v down to 90 or 80v as the load increases, that usually indicates a problem with it not getting enough fuel. On these inverter generators, the carburetor is controlled by the inverter by the use of a throttle motor. As the inverter senses the demand for more power, it increases the throttle to deliver more horse power of the engine, thus meeting the demand for more electrical power out.
I have seen a couple things cause this. A partially plugged jet in the carburetor can cause it. A bad throttle motor (Part# 21) on the top of the carb can go bad. I even had one that I caused myself by not putting the little spring (part #20 on the exploded view of the carb) that sits under the throttle motor in correctly.

Have a 2000w inverter in my rv just purchased 3 months ago a olp light on and constant beeping what is the problem ,


With inverters and generators, the power rating is usually off by about a quarter.
Watts and volt-amperes are totally different and sometimes inverter manufacturers don't tell about the difference. A basic rule of thumb is to take whatever the inverter is rated for and knock a quarter off. So, in your case it would be best to assume a maximum rating of 1500 watts.
Also, inductive loads like drillers (electric motors) usually have a start-up current 3 to 8 times the rated operating current. Meaning that 100 watt driller will draw 300 watts to start up. So, if you use an electric motor rated at 700 watts, its startup load would be 2100 watts or even more and thus trigger the inverter overload switch. Hope this helps you.

Generac generator on auto runs weekly. light green previuosly green. now red. what causes this??


Hi and welcome to FixYa I am Kelly. Your red LED is telling you that it was 1. overloaded. 2. has low voltage 3. overheated or 4. short in the powered circuit.

OVERLOAD LED (red): Lights up if the generator experiences
a load greater than the rated output, low voltage, overheats or
the powered circuit experiences a short. The output is stopped
even though the engine keeps running.

I do not know which of the 4 conditions caused your red light. If you have the read light with no load I would suspect low voltage from the generator / inverter. If it overheated you will also get the Red LED with no load.

Thanks for choosing FixYa.

You may be UNDERLOADING the generator and it may be unstable with such a light load... see if it might behave running a heavier load... put a 100 watt light on it as a test,

2 generators 1000 watts invertors


NO! DO NOT ATTEMPT THIS. The problem is that you cannot maintain the phase relationship between them. Both of the generators must turn at precisely the same speed and precisely together - which is virtually impossible without connecting the two generators together on a common shaft, which would be impractical to the point of ridiculous.

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.
