Breakers could be bad, but no power to all the plugs, including the 240vac plug indicates something else going on. Either residual magnetism has been lost (has it been a while since it been ran?) and needs to be flashed, capacitor or diodes in regulator are bad, or there has been damage to the rotor or stator. There could also be a problem with the brushes on the rotor as well.

Also, if engine is turning too slow, the alternator may not kick in as well. Make sure that you are turning either 1800 or 3600 RPM, though it is a little hard to do this without electrical output. You might try playing with the governor while a lamp with a sacrificial incandescent bulb is in it. If the engine speeds up, and the bulb lights, then governor needs to be adjusted.

When I plug in a tool, it runs fine, when I plug it into my house with the breakers all off, it blows the breakers on the generator? My Honda 2200 watt works fine this way?

I think there is overload .kindly measure ur load of consumption. Do not run the generator set with high load it can be cause of circuit breaker Tripp off .

How do i check if a circuit breaker is good or bad?

Check for voltage on the side the stator wires feed into, then on le breake rload side. If you have no power either place breaker is good, if you have on one side only it is bad. If you refer to how to check if it can handle it's rated current you will need a load bank and apply rated load to the generator and see if it trips when it should.

Why is the circuit breaker on my generator working backwards?

This could be ground fault type breaker. Remove the breaker and look at model number. Verify on google. If breaker is bad you could replace with generic breaker that will mount on your panel. Simple push button breaker will work ok. You can add ground fault with pigtail plug. If however breaker is good, there must be a short. If someone replaced the 115v plug with home type, you will have short at plug. Good luck

I have a briggs and stratton 8500/5500 generator which I am using to power an air conditioner on a camper trailer. I just recently started having a problem where the one circuit breaker keeps tripping when...

Hello, First figure out what the load per leg is on your generator. Are you using the 240 Volts because this is two 120 AC volts legs and they are 120 degrees out of phase with each other.

You will need to figure what the power factor is for each phase on this generator. To figure the power/wattage by using ohm's law. Voltage times Current will give you Watts. Example: If the generator is generator 240 volts the maximum current available is about 23 amps. The maximum current for 120 volts will 46 amps. Therefore, the maximum current per 120 volt circuit is 23 amps for one circuit and 23 amps for the second 120 circuit..

I would try replacing the circuit breaker with the same amperage breaker. Also, watch what the generator load is per circuit. You can install current meter for each circuit. This will give a good indication of which circuit is pulling more load than the other circuit. GB...stewbison

Runs good circuit breakers good,no power

I had the same problem with the same generator. It has served me well for 10 years but recently broke. Apparently it the AVR circuit board. A common problem with older generators. The bad news is it's expensive. After much searching I found it Mitsubishi part # KYC031002210. Price, $350.00! Good luck.

What about when you have it powering the motorhome, without AC on, does it trip then? Do you have anyone you know with a multimeter and knows how to use it? How about buying a plug in voltage meter at a hardware store as a good start. You simply plug it in to a receptacle in your motorhome and it will tell you the incoming voltage and they are not very expensive. That will help diagnose generator problem.

Motor runs but have no power coming out of outlets of mygenerator

1 - Check the circuit breakers on the front of the panel where the outlets are located.
2 - Make sure the black molex plug on the back of the panel where the outlets are located is plugged in securely.
3 - Carefully take the plastic endbell off the generator ( you'll need a 7/16 inch wrench and socket) and look for broken or missing brushes, broken wires, etc.
4 - If you're not up for #3 take it to a good repair shop. :-)
