AC and genset

[spirt320]

Testing my genset yesterday and just noticed that when I switch from shore power to the genset my ac/heat turns off. I thought the genset also powered the ac etc...? I have the unit set on heat at around 65 degrees to keep the cabin at an even temp here. Should i have switched it to the cool mode on to see if that would work with he genset?

Your genset should power your heat and a/c. Check to make sure you have everything turned on.

I agree, but have not used it in a long time. The A/C and heat is working, just when I switched power from shore to genset, it would turn off. I was doing some radio maintenance and opened the cabin power distribution panel to get to the Sirius radio receiver and wonder if a wire got unplugged or something. Guess I will have to go back up this week and check it again. I keep the air conditioning switch on the power panel in the on position always.

So, your AC/heat shut down at the switchover. First, you should consider if it would be advisable, depending on your setup, to shut everything down, and let your genset run for a short time, before putting a load on it. Conversely, take the load off, and it let cool down for a short period, prior to shutting it down. But, in your scenario, are you saying even after the AC/heat shutdown, that were "NOT" able to bring it back up with the generator running?

Correct, so the AC/heat was on running and then at switch over it would immediately turn off. The thermostat panel would also have no display. When switched back to shore power, it would turn back on immediately again. I remember it all working last time I used the genset. I was doing some work behind the switch panel with the stereo and Sirius receiver which sits to the side behind the 12 volt distribution panel and am now wondering if somehow something got disconnected. I didn't think anything did, but may have missed something. Is there another breaker for the AC/Heat system somewhere that I may be missing as well?

Does your genni support the other items or are they all turning off (ie no power from genni)? Also are you turning off the A/C unit before switch over? I am not positive if you must, but I used to turn everything off, switch over, and then turn each item on one at a time on the panel.

I will have to go back and check more closely. Before when I used it and made the switch, the AC/Heat turned right on. I do agree that I need to turn those items off when I switch over to warm up the genset before placing the load on it. As far as the other items, it is hard to tell. when I switched over, the fridge light was still on etc... But they can also just run on battery. The only thing I noticed was the AC/Heat not running when switched over. As stated below, I did open up both of the distribution panels below the stereo to work on the stereo and related components, and had to pull the switch panels out a bit and to be able to access in there and run some stereo cables etc... So I am thinking that I may have unplugged something, or tripped a breaker that is related to the genset and didn't know about it. I will try and make it back up there in the next couple days and backtrack through everything as well as check all breakers and switches. That is what happens when my wife is texting me non-stop while I was busy working on this stuff and making me rush to get back for Valentine's Day dinner. LOL.

Does anyone know if the genset would still run if the customer connection fuse or a similar fuse was blown? I am assuming that if the customer connection fuse was blown then no output power would be going to to the boat to power things, but that the genset itself could still be operable to run. Just a thought as I read and research this until I am able to get back up to the boat on Wednesday.

This is my thought. I had a Similar issue that had the switch/fuse turned off directly on the genny. Started and ran fine but provided no power even when switching to genny at the panel.

I agree. Will be up there Wednesday to really check it out. I didn't have enough time to stay there this past Saturday and troubleshoot it like I would have liked. I will post after I figure it out. Thanks!

Sorry to change the subject, but my 260 DA doesn't have a generator and I can't afford one. Any comments about a honda portable 2000 W generator. Wondering where I could put it, could you put it in the engine compartment and run the blowers? Bad idea?

Fish - this thread is specifically about a person's question regarding his AC not working when on the generator. But, the "to the point" answer to your question is "only do this if you're OK with dying". There are TONS of threads on here about this ill-fated idea. Search and 'ye shall find - if you want a more detailed explanation, search for a comment by fwebster.

Greg,
Steve here, also have a 06 320.
On more than one occurance, while stepping down entering the engine room I have switched the power from the ginny off.
Toggle switch right there in the way, down for off, up for on.
this could be your issue as well,.....no power coming out from the ginny to your panel.
Hope this might help.

Put it in the head compartment and run your vent fan. This way the toilet seat will stay warm and the gen will stay dry. Should be just fine. What could possibly go wrong?

 

[spirt320]

Steve, that is probably what happened. I will be up there in the morning to check it all out. All of the major services were done back in December and most likely my tech probably bumped it. I hope that is all it is. Thanks!

A comment?!?!? Dennis, you say that like Frank only commented on this once. :smt043 However, Dennis is right, venting exhaust into the boat is colossally stupid, let alone all of the other bad things with a portable gnerator on the boat.

Duh...guess that's why it's good to you screen names...no one can tell how stupid you are

 

[Fish Peddler]

Will do. Thanks Man

 

[spirt320]

Thanks to all who helped. Of course it was the little breaker switch on the front panel of the genset. Must have been knocked when service was being done. Glad it was nothing real this time.

We (me included) don't get the "freebie" fixes all too often - enjoy it! :smt001
