2007 Fleetwood Providence Electrical issue

I have a 2007 Fleetwood Providence diesel pusher that after sitting stored with power on tothe RV, developed a problem when I started. I noticed that all the gauges did not work except the air gauges. Repairs had to be done at the Freightliner repair center, (Cobie Neely , Decatur Al.). After replacing the jumper wires in the dash unit and several gauges they got in to work. $1350 later. After I drove it home and had some other repairs to the readend , the same problem returned and back to the Freightliner repair shop. This time they said they had to reset the computer, $140 (reduced from $500) I picked the RV up and drove it 30 miles and parked it, plugging it into power. I came back 1 week later, started the engine and the problem reoccurred. Now the RV is in the shop again. Has anyone experienced this, need help!

No ideas, but suggest calling Freightliner Custom Chassis Help Line and ask them. 1-800-FTL-HELP. Have your chassis VIN handy.

I have a 2007 Fleetwood Excursion. It sounds like you may have the same dash and gauges I have. The first time mine went out I replaced all the pig tale wiring. The second time it was the LBCU (Light Bar Control Unit) maybe the same as you called the computer. The LBCU takes the data from all the sensors and interprets the raw data and sends it to the gauges. So if the LBCU is bad all gauges fail except the air pressure. The data comes to the LBCU through a long data link running the length of the coach. Intermittent breaks or corrosion in the junction points along that link can also cause problems. Hope this helps.

The repair shop a Freightliner shop, replaced the light bar and all the pig tails and a couple of gauges about two months ago.
Today the shop called and said they unplugged all the pigs tails, when they plugged it back in everything now works. They are still trying to find the original problem.

At my Freightliner dealer, I think motorhomes were a side business. When I left their yard, my coach batteries were dead and my odometer had jumped from 57000 miles to over 90000 miles and they did not have a clue. Turns out even though the LBCU said miles, it was showing kilometers. Freightliner figured that out and told me how to fix it. I think I knew more about the instrument panel then my dealer did. When all gauges went out, they wanted to change all the pigtails. I said no and had to explain that the gauges work in series so the only way a pigtail could cause them all to go out is if the first one between the LBCU and the first gauge was bad. I explained that if a pigtail was bad between the second and third gauge, then the first two gauges would work and the last two would not. In your case, if they think it is a gauge, they can plug each gauge directly into the LBCU and see if it works. I understand a common problem, especially after setting unused for awhile is corrosion in the data link. Apparently there are connection terminals that get corroded and block data flow. There could also be a place where the insulation on that wire has worn off or been chewed off allowing an intermittent short. I learned all of this by talking to Freightliner. Great people, very helpful.
