Hi Ho: Any internal combusion engine requirese 3 things to run: fuel, air, and ignition (spark). We were recently unable to keep the engine running after the starter motor was disengaged. Air filter ok, spark ok...Suspected that the fuel was also ok since I had replaced the filter less than a year ago. Disconnected the fuel line at the filter and was surprised that no (little) fuel came through the filter. Took the filter out and cleaned it and voila, back in business.

It's easy to see which of the 3 things is missing. If they are all there the engine should run.

Of course it's also possible that the processor shuts things down when it shouldn't, but that's another subject.

Dirk

Hard to find that spark in a diesel engine.

Cinequip,

Our Xantrex power share maxes at 30 amps as well. I had ours set at 15 amp today for a NoWaCa rally where we were all on 15 amp and forgot to set it back to 30 amp. I had the same problem with the generator shutting down and not taking the load until I set the power share back to 30 amp. Once reset to 30 amp it took both roof AC's just fine, as it usually does.

i do find I'm better off to not have the AC's in queue when I start the generator and also have the inverter enabled. The generator comes on line faster and more reliably for me if the AC's are not queued.

That's interesting, Bill, my generator works completely the opposite. No matter where I set the Xantrex power share the generator will still quit unless an air conditioning unit or some other AC power load is ready to be powered. Cummins Cal Pacific, after throwing up their hands on the whole affair, thought the generator shut down might be because of a mismatch of the Onan "brain" and the Xantrex. I think they wanted to sell me an Onan inverter. My next attempted fix will be to see if there is an update for the inverter. At the time the coach was with Cummins they said my inverter had the most current update revision.

Scott:

The * in "30*" merely means that was the last setting before you started making adjustments. It is NOT a default number. It merely refers to your last setting. You will see it in all your adjustable settings.

What Xantrex models do you and Old have? If your inverter is designed and wired for an Alpine, it ought to have 50 amp capability. My RS3000 and earlier RS2000 both had at least 50 amp capability. I'll need to check what the limit is. IIRC my Xantrex Heart-Interface did, too.

Takepride,

The RS2000 settings will only go to 30 amps. My new RS3000 and the older unit in my 2002 would set to 50 amps. The only thing this setting does, is to limit the amount of power used for the charger, it does not effect the other coach 115 volt circuits.

Thanks Dale, good to know.

Considering how advanced energy management is for homes (and has been for 20 years), I'm surprised the Xantrex is so primitive and lacks many capabilities. Seems "load shifting/shedding/management" are just myths.

Problem Solved! I leave one of the bedroom reading lights on (they're 120vac for some strange reason), and the genset always starts up and takes the load fine.

Back in 05 when we got our coach we had some strange goings on with our generator in that it quit, would not start if the engine was running, etc. I spoke with Mike Glazier @ WRV, who I got along with very well, sent out some relays and a wiring diagram. I installed the relays and wired accordingly. Since then I have never even thought whos first or what is running or what is not. Everything has been terrific. I would be more than happy to share this info with you if I could find it. I will eventually. That is the opposite of assume. Possible Mark H. could shed some light on that information as it might help some of you with your gen. problems.

We always leave a nightlight on behind the drivers seat in the receptacle that does not go through the inverter. That way we can tell if the generator is running when we are traveling or when we connect to shore power and are leaving the coach. We can just lean in the door and see if the light is on. Maybe that would suffice for your generator issue as well.

Is there anyone you don't get along with very well?

To my recollection no, course my recollection is real bad. Speaking of getting along did you and the other "gentlemen" resolve that brake issue. Driving it carefully was quite a comment or however he put it.

Scott, did you ever hear about the Xantrex update, my Genset is doing it too. I hate to queue up a A/C for the thing to work correctly. I will send them an e-mail and see if there is an update for this issue, we are heading out soon and it needs to work when I need it to work.

Monty,

No I never did an update. I solved the problem by simply leaving something on, so the genset comes up with a load. It doesn't have to be the A/C.

So far this has only been a problem under the following conditions:

1. HOT day.
2. Just stopped driving (batteries fully charged, so no load on charger upon genset startup).

Let me know, if you figure out how to get an update.
