We previously posted that our generator in our recently purchased GMC would run but would not produce power in the coach .
Â
The RV shop that told us we needed a new board & said that it is not wired correctly.
Â
Before we purchased it, the wires had been chewed. Someeone worked on the wires but did not do it correctly. They bypassed the board & wired straight to starter so that the generator would start. It runs great & sounds great. Too bad it doesn't do itsob. Â
Â
It is not wired to the F1, F2 & brushes, according to the RV guy. He said until it is wired correctly, it can't produce power .No matter what we do.
 .
Tom, you had asked these questions:
Â
Did it produce power? Not since we had it.
Does motor run? Yes because the board is by passed & wired direct to the starter.
Was it running, producing power under load & then quit making power? Never produced power since we have owned it.
Â
Tomorrow the dash air is being checked at an auto shop. Hopefully, that can be repaired.
Â
Tom, when I express my concern of traveling to Branson without AC, you said to remember when I was a little girl with no AC. That’s been so long that I can’t remember & besides I didn’t know any better.

Get it to Branson and there will be many there able to help.
Sounds like new control board, this affects only the engine running, not the power output. Need to look at the wiring of the generator portion and see what the story is there. Hard to diagnois from the distance. Hopefully, just a few new wires.
Would not recommend running the engine very long without a working control panel. The jumper just helps determine where the fault might be located.

If you don't want to have someone handy tinker with your board, buy a new one from Jim K at Applied GMC: http://www.appliedgmc.com/prod.itml/icOid/628| Quote: |

There are TWO completely separate problems here. One is the control board that allows remote start and stop, protects the engine from low oil pressure and so forth. The other is that the generator section does not produce power. Someone has bypassed the control board and the engine is running unprotected. That has nothing to do with the lack of power being generated.| Quote: |

Probably true. Get it to Branson.| Quote: |

Any automotive AC shop with reasonably capable mechanics can get the dash AC working. Trivially easy if they will charge it with R12. If they insist on converting it to R134a, the cost may put you off, but it can be done. To convert to R134a, they have to fix all the leaks, flush ALL the oil and contaminants out of the system, replace all the O-rings, they may want to replace the dryer/dehydrator (less than $30 at Applied GMC). They will fill it with oil, pull a vaccum, and charge it with R134a. Done. (If they want to replace the expansion valve, steadfastly decline to allow that.)
After you get it back, if you want better cooling with less horsepower to the compressor, post here asking for someone to help you convert it to Duracool when you get to Branson.

Betty,
I would suggest ordering a pair of Wind Wings from Ragusa:
Click on the link below:
http://www.ragusarv.com/
Click on Exterior Items
Scroll down to Item RV-24 Wind wings.
To fit these Bill will need to drill and tap two holes in the lower part of the window frame. You can then open the small windows
and get a blast of air through it. It's enough to keep you relatively comfortable while driving.
Regards,
Rob M.

I second the wind wings. If you have no ac these are the next best thing.

For max air flow with wind wings, open the toll window all the way, rotate the wind wing for max air deflection into cockpit, then slide toll window forward to match the end of the wind wing. Puts the air on the driver and passenger.
Works for me.

As someone stated, the control board - the PC board under the metal cover on the side of the unit which has about 9 wires that come out to a white plastic square inline connector - has exactly nothing to do with the generator portion of the set. It is the engine controller, and can be bypassed for testing or to run the genset when there is a problem with the oil pressure switch not operating. The brushes do not connect to it.
How far are ya from Robin in Jackson? He's the closest guru on Onans likely.

I'm a far sight from a guru! I'm just a brave amateur! :) Betty is about
three hours from me. Im working six day weeks, Sunday is an off day for me.
It's a week till Branson. If she can put up with no roof air, she'll find
all the help she could ever want in Branson if she's coming.
I could head down on Sunday for a day trip and see if I can make it go. May
be something simple. I can post video from my smartphone if I need to
consult the hive mind...
I could pitch it to my wife as a fun little trip out of town. Maybe some
shopping or dinner or something. :)

Robin, that is very kind of you but we would impose on you to drive 6 hours on your only day off. If that was necessary, we would at least bring it to you. But we are going to Branson and hooray the dash air is cooling. Its not fixed because the compressor is leaking but it's holding a charge. We are leaving Tuesday & will be in Branson Thurs.
I guess I sounded like a whimp with no AC.
We are looking forward to meeting everyone & thank you again, Robin for your very generous offer.

Before we purchased it, the wires had been chewed. Someeone worked on the wires but did not do it correctly. They bypassed the board & wired straight to starter so that the generator would start. It runs great & sounds great. Too bad it doesn't do its job.
It is not wired to the F1, F2 & brushes, according to the RV guy. He said until it is wired correctly, it can't produce power. No matter what we do.

If a rodent chewed wires in the Bell Assembly and that is why F1, F2 and the brushes are not "wired", here is some help in tracing wires. The colors are bogus, I just colored the illustration to help make them more traceable to the schematic. If you click on the picture on the photo site, the colors of the image that pops up are sharper and easier to resolve than the picture.
http://www.gmcmhphotos.com/photos/onan-the-barbarian/p50838-onan-6kw-bell-assembly-wiring-illustration-and-schematic.html
Any Onan experts, please verify that the illustration is correct.
If there is nothing wrong with the wiring, then the bridge rectifier is most likely the culprit, as that is common to both the field windings and one of the brushes.

If you are going to Branson, see Blaine Merrell on Vendor's row. He has got wind wings with stainless steel brackets in various colors. It only take a few minutes to install them. I just talked to Blaine on the phone and he will loan you an 8/32 tap to install them.
You need these with or with out Air Conditioning.

Welcome aboard Betty. Part of the forum's function is to save people from bad advice from those who are not familiar with GMCs. I won't be in Branson as we are heading west to a different reunion of friends. Have someone safety inspection 'look over' your coach to see what might need attention. I replaced the fuel line to my Onan today as it was installed by Cinnabar a few years ago but had cracks and leaks were starting as it was not barrier type ethanol resistant hose. Something to be aware of. Also, if Dave Lenzi is there doing front end inspections, get on the list to have him look at all your steering parts. Only takes 15 mins and he can tell you what parts are good and which might need replacing.

Betty, If your coach has the aluminum track for a curtain installed behind the seats, install a clear plastic curtin and keep more of the cool air in the front of the coach.

For those who have them, do these force flow into the toll windows? On my 23', with the windows open, air flows in the rear side windows and out the toll windows... which is OK, but the toll windows set up a very annoying drumming when open. Do the wind wings stop the drumming?

Of course, you & Dana are always welcome to take a trip down to visit.
The auto repair that charged our dash air said that they don't usually work on "old" vehicles like this. Now we are talking about a coach that has been redone inside & out. Nice paint job except for the ram head on each side (I don't like that). When Rob saw it he said it was a Clasco coach.
We are insulted. They did not ask for the year when I made the appointment. I guess that was a good thing.
They did get us in & charge the dash air so I guess we have to suck it up.

The wings create a steady flow of air into the cockpit. If you are curious how well they may work, next time you are driving cup your hand slightly and stick it out the toll window.

They will force air either direction. The are hand adjustable to force air in or pull it out. Sometime we run with it in the in position and sometimes we run them out. Also sometimes we run one in and one out.
Look here at the second picture down. It is not very good but you get the idea. We use them all the time except when the AC is on.
