Hi my name is Robert...

What is the make and model of the generator? DO you have to plug in a cord to allow the AC power into the RV OR you start the generator and you have power available?

On the generator should be some breakers, most have one or two breakers, on some there is a side panel you have to remove to get at the breakers.

IF the generator is running and you have NO AC power inside the RV I doubt it is a fuse issue, normally a fuse is for the DC side not the AC side.

IF the breakers on the generator are not tripped you could have a faulty Transfer Switch (TS) the TS detects the incoming power source and switches between shore and generator power, when the TS fails you will get no AC power on one source, it can happen on shore power or generator power......

I saw your response, it takes some time to type a reply, I will continue with my answer so look for another response when you can.

If you have AC power going into the TS and nothing is coming out then it has failed, the TS can be located in a few areas, sometimes it is next to the shorecord in box and other times it can be inside the RV, under the bed, in back of the breaker panel etc. BOTH the SHORE and GENERATOR cord will go to it.

IF you have NO AC power at the the TS with the generator running then it sounds like a problem with the generator.... Hope this makes sense, if you have more questions or cocnerns please feel free to contact me, I am around daily and respond WHEN I can....

Just so I am clear the AC power would be the outlets, TV, Microwave it is possible to have the AC power but be missing the DC power, when the generator is running or you are plugged in the power converter will take the AC voltage and make the DC voltage, so if you DO have the AC power let me know.....

Make sure you also do not have any GFIS that are tripped, these will be outlets with a test and reset on them, they are normally in the bathroom and or galley but can be just ablut anyhwere else.... Robert
