Generator/No Power
2002 Gulf Stream Sun Voyager with Generac generator. Has been running fine and putting out AC fine until today. Generator starts right up. However, nothing inside coach indicates running 110 volts through the system. I checked both 30 amp breakers on the generator itself and they seemed ok too but tripped them back and forth anyway. Is there another fuse I'm missing? What else can I do with this thing?

Check the Transfer Switch, There is a Time Delay Board inside. If it is malfunctioning, for whatever reason, There will be no power to the Coach!!
Remove the TS cover and check rear upper left corner,in the back. There you will see the TDB There is a Green LED light and a DIP Switch. The switch is set to "I" inoperative or "O" operative move switch to "I" and see wwhat happens!!!

I recently had the intake replaced and the engine seals resealed. I asked the tech if he knew of anything I should have replaced sinse the gen had to be removed from the rv. He said hands down he would replace the drive belt and belt hub due to the fract that if it should break the engine would run but I would have no power. I did have it replaced. I hope your problem is less costly.

Do you know the maintenance history on the genset?
Have you checked the GFI outlet reset switch?
It should be run and started at least 1 hour per month to keep the generator slip rings clean. If that's ok and you are mechanically inclined you could get a service manual for your model or call Generac for tech support. If not it may be time to locate a good tech to diagnose the concern.

I"m not sure of the maintenance of the generator. On the surface, it appears to be fine. It actually looks to be pretty well maintained. Oil is clean, new filter, etc. Tell me more about this GFI switch. All I've done is check the two 30 amp fuses at the genset.

I need to know more about this transfer switch thing. Is that under the bed with the 120 v fuses and the other electrics? I need to say again that everything associated with the genset was fine until today. It's always pumped out 120 before without any problems. But, I'm ignorant of the coach electrics in general. so, tell me more about this transfer switch. Is this the box that keeps the genset from pumping 120 through the coach with it hooked up to shore power?

Just like at home in bathrooms and kitchens some of the outlets are controlled by a 120 volt GFI receptacle. It looks like a regular power outlet but has a test and reset button on it. This may explain no power at outlets, but would not make any difference if the air conditioning is not working.

On our coach the transfer switch is in a plastic box that the 50 amp chord leads into. Open the cover as already suggested and you should see a small circuit board with a tiny dip switch. Flick the dip switch, then go back inside and trip the main house breaker. Then start generator, let it run for a minute, turn main breaker back on and see if you have power. Tripping the breaker is protection because if you do get power there will be no delay. If you have power this means you need to replace that little circuit board. Its not expensive and is easy to replace or was for me.

You need to find and have a qualified person to check the transfer switch. This is a set of contactors that select the incoming source of power into the coach. When the generator is started the voltage from the generator should trigger the transfer switch to activate power coming from generator. You can check for voltage from generator and to the load side of switch into coach. If the generator is not putting power out you need to get generator repaired. If the generator is putting out power but the transfer switch is not working it will need repair or replacement.

This is sounding more and more like the Time Delay Switch. I assume that this also what keeps you from running shore power and generator at same time right? It appears to me that this device is located under the bed in the bedroom. I'll check this out first chance I get. I'm betting this is the deal though. Hey would it help to try and "kick" it you might say but manually switching dip switches as suggested by others? Many thanks for helpful responses.

Thanks for the help. This has got to be all about that Delay Switch. It's under the bed so I'll check that out next.

Make sure that you unplug all power sources including battery disconnects before opening transfer switch. Ours is located in a outside compartment where the power chord leads in. When our delay switch went bad the generator would start and run fine but supplied no power. It only affected the generator. After flipping that little dip switch I used the coach this way for many months before replacing the circuit board. The switch is a by pass switch for the delay feature so I had to manually delay by turning the main breaker while generator stabilized each time. Transfer switch has a two year warranty. I had them mail me the circuit board.

News Update. I tried bypassing the Time Delay Switch. Tripped DIP switch but no go. I tested the generator input side of the TDS and guess what? It appears I'm only getting 4.75 volts AC out of the generator. When I shut down, I loose that little bit of course. Removed service panel on generator itself Exposing a lot of wiring. Also saw a red LED light that was not lit with Generator running or not. I feel that LED should be lit up when generator runnng. So, the problem is in the generator. Could it be something simple like some kind of regulator or something. Any other ideas?

Now that you know that it is the generator not putting out power, you will need to get a service manual and trouble shoot as to why. It could be a voltage regulator, brushes, slip rings, stator, rotor, loose connections etc.
