Oh my, when it rains it pours, lotsa problems all at once.

RCtime · 05-02-2013, 06:08 PM

Went to Pechanga RV resort casino 2 weekends ago, hooked up to 50 amp, running the AC. all was well, left and came back 2 hrs later and the AC. was shut down with the #1 compressor circuit breaker tripped.
Anyway, took it to Mobillodge, authorized Colman repair facility., diagnosis, #1 compressor shot., new one on order In and out all said and done $1100.00 .
But, while I was there, he wanted me to fire up my 7500 quiet diesel genny. I did, started right up, however when you put a load on it it does not rev up, and promptly shuts down.. doesn't run more than 40 45 seconds and shuts down. I think its code 1=33 which is overheat either temp or heat sink. Not to sure on the codes though. Obviously it is not overheated temperature wise, it hasn't run long enough.
Strange it was coupled with the AC incident.
When it starts right up I see about5- 6 amps on the display, then it will shut down 35 40 seconds later and if you put a load on it , say the water heater etc it will not increase rpm.
However this seems so secondary to me right now, my pal for the last 10 1/2 year, my dog Charlie I had to put down yesterday. He has been a good camping buddie.
Any ideas anyone.

So sorry to hear about your pup. There are just no words to make it better.

As for the electrical issues... how was the weather? Any electrical storms in the area or did others have any issues with the park power? Do you use a surge protector?

I'm sure some of our Onan experts will be along soon with help on the codes.

Best of luck and hang in there.

Rick

RCtime · 05-02-2013, 06:37 PM

thanks Rick, I am sure you understand. I did have my 50 amp. surgeguard on and it was not tripped and showed no issues.
Looks like you have some great traveling buddies also.

Sammie · 05-02-2013, 06:40 PM

RCtime, So sorry to hear about Charlie. It's so very hard to lose a best friend like your buddy Charlie.

As far as your generator shutting down problem, it sounds like you might have a temperature sensor problem. FIREUP had a similar problem that he described in this thread. http://www.irv2.com/forums/f101/7-5-...ns-136251.html

I'm sure he will chime in later with his ideas that will help you.

Also sorry to hear about your dog. We've been there several times and it always hurts to lose one.

Agree with the idea that you may likely have a failed/failing temp sensor which is telling the genset it is overheating when it obviously is not. This past winter I dropped my genset to replace that gizmo and also replaced all the coolant hoses, drive belt and the thermostat. Unfortunately, on the Journey, none of those things can be done unless the genset is removed from the coach.

I posted a thread about the job if you might want to DIY. If not, be prepared to pay $800 + to have it done.

I read your post, alas, I will pay as I do not bend in the right places anymore.
CONGRATULATIONS on your new coach, its a beauty and quite an upgrade from our Jouneys. I thought after you had yours painted you would be driving it for awhile.
After I get my AC re-installed next week I am persuing my genny fix.
I hope its a simple fix, but I expect its not.

AFChap · 05-03-2013, 08:37 AM

Has the generator been recently serviced? I had the same codes after I had mine serviced (coolant replaced) and found the shop didn't properly purge air from the system. I followed the manual instructions and got a lot of air out re-filled the coolant, and problem was cured.

FIRE UP · 05-03-2013, 11:10 AM

RCtime,
Sorry about your dog, we're rapidly getting more and more attached to our new little home and traveling companion, a mini Schnauzer. Things sure are different when you've not had a dog for almost 18 years then, there's one beside you almost day and night.

Anyway, if, you truly have the infamous code 33, then it's quite possible you have what smlranger, myself and many others have had to deal with. And that's a faulty temp sensor. There's no guaranty here but, it sure sounds like it. SMLranger and I both did fairly intense "tear downs" of our 7.5QD units and, he got lucky on his and the temp sensor came out without almost no trouble at all. But, on mine, IT WAS WAR!!! I won. But, not without a serious battle.

Whether you plan on doing it your self or, having it done, the work can be not too expensive or, based on just how much trouble that little sensor is to get out, it can get nasty. You see, that little sensor looks and, is almost shaped just like a spark plug. But, it's got a tip on it that has fairly tight clearance with the surrounding housing that it's mounted in. And, due to in sufficient flow characteristics of the coolant in its immediate area, it gets a "hardening of the arteries" so to speak.

Corrosion slowly starts to encompass that little sensor tip and eventually, it completely fills the small void, surrounding the tip. When it does that, the readings the sensor takes start to become and, in fact, become false and, since that temp sensor controls much of the operation of the gen itself, the gen can only react to what the sensor tells it to do, which is false.

Sometimes that little guy pops right out and the cost and the time are minimal. But, as in my case, that little guy fought me 'till the very end and caused me grief.

So, when you get the rest of you A/C work done, and, then it's time to tackle the Genny, hope it's not the battle I had to fight. Let us all know how it comes out in the end.

I agree with all you have to say about the temp. sensor. To answer AFchap, no I havnt had any coolant replacement, just oil and filters with about 30 hours or so run time since.
What still puzzles me though, is that the genny will not ramp up rpm when a load is put on it, If indeed it is the temp. sensor will it affect that also?
I do have an authorized repair facility within 4-5 miles of where I store my coach. Smith Powerhouse Inc., on Lakewood Blvd., in Bellflower, Its factory authorized so I guess I will be talking with them.
Scott, My wife and I had a mini Schnauzer about 3 dogs back. He was smart as a whip and a really a nice dog. I think that was back in the 60s.
I guess the fire guys are busy, isn't is nice to be retired. My grandson got recalled and put on a strike team headed to one of the fires.

RCtime,
Sorry for the late reply. Pertaining to your "ramping up" of RPM for added load on your genny, I cannot answer that. There are electronics in there that sense the load and, apply appropriate throttle to the engine to accommodate the load. Your sensor handles cold start situations, and over heat situations but, has nothing to do with the throttle application. It's kind of ironic that you're talking about this right now because I think mine is "ramping up" too much for a given load. I'm by far, no expert here but, this is just an opinion.
We're presently down camping at The Springs at Borrego and due to full hook ups, no genny is needed.

But, when we return home and, I find some time, I'm going to take the big beast down to a local Onan specialist and have him run some tests on it to see if there's any issues and also to see if my opinions about too much RPM for a given load is normal or not. Right now, the Sophie dog is pacing back and forth on the dash, like on a guard tower, making sure that nothing, and I mean "NOTHING" gets by her. When she thinks all is well on the western front, it's LIGHTS OUT!
Scott

I'm also sorry to hear you lost a traveling companion. As to your Onan I have a problem with mine and have had it to Cummins and to a local Winnebago shop and have not yet resolved the problem. When the connection is made to the wiring harness near the generator that goes to the remote start locations the generator will start run briefly and then shut down. As a thought you might disconnect that connection and try starting it from the generator to see if it performs as it should with that connection disconnected. My generator puts out power and runs as it should as long as the inside remote start is disconnected.

Bug512 · 05-05-2013, 07:15 PM

Sorry to hear about Charlie, we went through the same thing with our two early in April. Hopefully a new traveling companion is waiting for you.

Others will know better about that generator set.

As for the AC repair, that price sounds reasonable. I need a condenser coil myself.

RCtime · 05-08-2013, 06:18 PM

Ok, here is the end results I have back from my generator problems.

I took my coach to Smith Powerhouse and here is their estimate of repairs.
The repair cost they gave me is the worse case scenario and may be less.
Failure of temp. senser. They are going to drop the genny from the coach and replace the temp. sensor. They said they are often hard to remove and if they have to drill it out and retap the threads the quote is for that labor. If it removes easily my bill will be less.
complete service of genny, oil, filters and fuel filter., replaces all hoses and belts and radiator cap. Includes all oil, filters and parts and taxes.
$1064.16
Smith Powerhouse has two excellent reviews in the RV REVIEWS and I felt very comfortable dealing with them.

RCtime, I see we run in the same circles. I was born and raised in Bellflower and frequently shop at Deluxe RV right down the street from Smith. That doesn't sound like a bad price to me for all that service. I will keep them in mind for future service on my generator.

That doesn't sound bad at all based on my own experience in how much work is involved in doing it. Tell them to heat the sensor a bit with a propane torch, spray it with something like Deep Creep and it will come out of there easily. While they are in there, ask them to also replace the engine thermostat.

RCtime · 05-08-2013, 08:07 PM

Excellent suggestion about the thermostat. I will call them tomorrow.

Thanks Ron

JohnRR · 05-08-2013, 09:08 PM

Thank you for the update.

RCtime · 05-14-2013, 06:55 PM

Here is my last update.

yes indeed Smith Powerhouse came through. The sensor was frozen solid and cracked they said, definitely my problem. They broke it off trying to remove it and drilled it out.
All is well now, completely checked out, back in my coach, load tested serviced and all new parts, yes the thermostat was included.
Same price as quoted. Pick it up tomorrow and have my AC installed Thurs.
Heading to Wyoming. See Ya
Recommend these guys if you get an ONAN Genny proplem.

My Dear Friend Ron....We are saddened to hear about Charlie... There is no pain as the loss of a Family Member.
When God opens the door and introduces you to your next Pet, accept it with open arms.
No one will replace Charlie but knowing you the place in your Heart is open to a new replacement.
Maybe we will meet again but till then, Keep smiling.

Thank you so much for your kind words. It has been 5 years or so now when we were camped next to each other, and you met Charlie. What a pleasurable experience.
I hope all is going well with you. I truly hope that we will meet again.
Ron
