I have a Wacker portable Gen gs 5.6 It runs good but it also don't put out power ether

Does it have brushes that need to be replaced. Check with a power tool supplier for advice/parts to repair

Good Luck

if the sensors are okay, it might be the compressor overheating, my portable ac (moretti elite ac) is also behaving the same, especially when i turn the fan to max. the compressor shuts down about 7 mins and turns on again in about 5 mins, now i found out when i turn to medium or low the compressor runs normally. i think when on medium or low setting some of the cool air directs/channels to the compressor thus cooling it more.

check the fuse box

Steve,

The microwave alone shouldn't cause a problem for the generator as even the most powerful models run about 1200 watts or about 10 amps. An air conditioner on the other hand, can draw considerably more power to run depending on BTU size; 15 amps and up is not uncommon (and even twice as much as that though only briefly when starting).

If these were the only things connected and on, the generator should be able to handle them - again depending on the BTU size of the AC unit. Generators state their capacity in Watts, but must of the devices we connect are in Amps. Calculating Watts in an AC circuit is complicated, but pretty close to the much easier Watts in a DC circuit for most residential settings. Here's how it's done:

Watts = volts x amps. Pretty simple stuff. Your generator is rated at 5500 watts. The microwave is say, 120 volts / 10 amps - which equals 1200 watts. The generator has 4300 capacity available now. Suppose your air conditioner is rated at 120 volts / 15 amps - which equals 1800 watts. 4300watts - 1800watts = 2400watts capacity is left. But, the starting current for the AC is as much as 25 amps for a few seconds (and once started drops back to 15 amps) - which means there's only 1200 watts capacity left. Add up the rest of the appliances you're running at the same time (TV set, Cable / Satellite box, stereo, toaster, lights, computer, etc.- you get the idea), and you can see how you might have exceeded the 5500 watts capacity of the generator for a few seconds. It's at these times that your hear / see the generator speed falter and sputter, lights dim, etc.. If this is happening a lot, you may need a larger or additional generator.

I hope this helps and good luck!

Possible solution: if it's been sitting idle for some time, you might need to flash the windings. see this link:

If you're uncomfortable doing it yourself, your Onan dealer can do it in 10 minutes.
Don't forget to check the circuit breaker on the generator itself!

Yes, it must be vented to the outside, even if you're using central AC, too. The reason being is if you don't vent it to the outside, the hot air and humidity that normally goes thru the duct and out the window, will stay in the house and your Central AC will have to run longer and harder to overcome this rise in heat and humidity. In addition, the room that the portable AC is in, will get extremely hot & humid.

Hope this helped you. Please let me know. Thanks.

run a 10 amp fuse, if it blows start looking for a short. do yourself a favor and rewire the fuse box to an up-dated box, glass fuses will only get harder to find.
Good luck

If the voltage system in Malaysia is 230AC then no problem. But if it is 110AC then there will be no sound. Check for audio click in the input green banana pin by touching with bare finger in the full volume control setting with the audio system. If audio click is present then sound system is okay. If not then, amplifier board circuit is to be checked of the sound system.

make sure your not overloading the power and Amp's out put. you'll also my need to have your set re-calibrated. most tags show, 3600 rpms at 60 hz 120\240 no load. over time you'll ether loss or gain rpms which well directly affects your power output. let me know. good luck

Your voltage regulator is at fault. Make sure you replace it with the exact same brand name and serial number or you will burn out the generator.Thank you, Dana
