You haven't given much information that allows anyone to help you, but it seems that you are having a problem with your boat. What sort of boat is it? How many batteries does it have? What kind of battery switches does it have? How is the generator wired to provide 12VDC power anyway? Ordinarily, your generator is providing 120VAC. The only 12VDC power that the generator provides is possibly from the attached alternator that is charging the generator's battery. Does the generator start from it's own battery? Does the generator battery also serve your interior loads? (that would be unusual) Have your messed around with your batteries or battery switches lately? Likewise, shore power is 120VAC, so the only way that could be producing 12VDC would be through a battery charger. Without more information, it seems that there is a problem with your "house" battery, battery switch(es), battery wiring or battery connections. If you have a multimeter, I would suggest tracking down the sources of 12VDC power to find where you have 12v DC and where you don't. That should give you some clue as to where the problem is located. Most likely, your house (interior) battery is dead, but when you run your generator or connect to shore power, you have 120VAC power and your battery charger(s) are turned on and providing 12VDC to your interior loads. Good luck.

Your generator may be putting out a square wave instead of a true sinusoidal (sine) wave.

There is usually a circuit in the microwave which monitors the AC line for timing purposes, and a square wave may not be interpreted correctly.

I would consult the manual or contact the manufacturer or installer.

SOURCE: I have a Coleman Powermate 5000 / No power output

Two suggestions. One: check for voltage from the secondary coil wires (if it has one). Two: unless stated do not do this, I have always flashed the excitor circuit through the 120vac receptical. Give these a shoot and I hope it works for you.

No, it will fry the unit!!!

You need the cigarette lighter adapter to bring the voltage down to 5V. More than 5V will fry the One.

SOURCE: My coleman 1500 generator runs fine but does not

Should be a circuit breaker on the side where the outlets are. Could also have a reset button that pops out. Good luck

SOURCE: Induction cooktop. Installed on a boat. Works fine

If the cooker is tripping off the power when connected to the genset then the induction circuit drain current of the cooker is higher than the generated supply.
If so you will need a genset with a higher rating so that the circuit on powering will stay to generate the EMI needed to heat or else the processor of the induction circuit will sense a lower voltage to cut off.
Also if you can use a isolation transformer with the correct rating or even a auto transformer it will help to regulate the problem.
Try checking with a voltage stabiliser to confirm .

Fridge in my 2012 Sterling 32RL

The fridge in your 2012 Sterling 32RL is most likely a 2-way refrigerator. This means it can operate on two power sources: 120-volt AC power (shore power or generator) and propane gas.
Typically, 2-way refrigerators do not operate on 12-volt DC power directly. However, some RVs may have an option to run the refrigerator on 12-volt DC power while driving, using the vehicle's battery system. This is usually done through an inverter or a converter that converts the 12-volt DC power to 120-volt AC power to run the refrigerator.
To determine the specific capabilities of your fridge, it is recommended to consult the owner's manual or contact the manufacturer of your RV or the refrigerator itself. They will be able to provide you with accurate information regarding the power options and operation of your specific refrigerator model.

Dometic 2652 has no power from generator or shore power fuses are good have been troubleshooting but no luck

At what voltage? 12 v DC or 110 VAC? Have you checked the circuit breaker in the power distribution panel? Is the outlet the 110 volt cord connected to hot? Is the 12 volt converter producing voltage? The only thing that exists between those components is wire. Look for the not so obvious problems like a wire pulled out of the back of the plug the 110 v cord is connected to or inside the power distribution panel for wiring problems.

Ac electric works with generator but not when plugged in to 110 volt from the outside

I would be checking the main breakers on the panel to insure one didnt trip when you added generator electric. is there a breaker on the outside line at the box you may be missing? Also keep in mind, although uncommon, breakers do BREAK and need replacing. are you competent enough to use a volt meter to check the hot leads on the box and at your unit breaker box to insure you are getting power into the unit? In some older units the switch between land power and generator power was to manually throw breaker switches but automatic processors have replace them now... I would say start at the residential plug in and verify power is where it should be along the route of the supply cord...from the meter forward... if you have a converter plug, say from the 220V 30 amp that you are probably drawing down to 110V household, stick that on the meter and plug in your toaster to insure there is power coming in....IF YOU DONT HAVE A METER AVAILABLE... otherwise...test test test... your generator probably broke a circuit somewhere... now just to find it..

Generator runs,no power at breakers or output plug,has been started and shutdown under load. 5.7 volts on wires coming from stator. All three wires.this is on a motor home.

have the unit checked by an authorized generator repair shop
if it was operating when shore power came back on there is every possibility that the generator or inverter has been damaged from the lack of synchronization of the sine wave

On a 2001 bayliner 2455 some of my electrical doesn't work on shore power

Do the lights or stereo work without shore power? If they don't that you have a dead battery. They are likely part of the 12 volt system and the shore power only charges the battery that runs them.

My fredom 25 inverter is not running the refrigerator in my motor coach when I turn the generator off or unplug from shore power.

Is the inverter rated for more power than the refrigerator draws (watts). Does the coach 12 volt power drop (at the inverter) below 12 volts when the refrigerator comes on? If so, you may need to increase the wire size from the battery to the inverter. Make sure that the voltage doesn't drop at the battery. If so, it may need replacement or a larger capacity battery. When the battery is being charged, measure the voltage at the terminals (which are hopefully clean)--it should be 13.5 to 14.5 volts.
