Wiring Harness Problems

Yahoo Message Number: 22716
I would be interested in hearing from anyone on this board who has experienced wiring harness problems.
My coach, a 2002 Allure #30760 is at a Cummins facility for annual PM.
I also reported a brief flickering of the Engine Warning light that recently occurred three or four times. Cummins people tell me the cause of the Engine Warning light is a short in the coolant level sensor circuit and they replaced the wiring harness. Problem is they say they have fixed several other wiring problems and more keep cropping up and they can't give me a diagnosis or any estimate of time or cost to fix.
(I have used the facility before, and believe them to be reputable, although if any repair job ever sounded like a scam, this one does for sure). I am very worried that all this wiring work that apparently has been done seems to have created escalating problems. I equate the wiring in our coaches to nerves and mucking with them is apt to lead to all manner of unintended consequences. I am befuddled because wires don't just go bad or wear out if properly fitted and installed in the first place. Does anyone out there have information about similar occurances in other coaches manufactured in late 2001 and 2002? My coach has had all the major problems - electrolysis, leaking slide-out hydraulic lines, failed ride height valves, failed oil pressure sending unit etc - that have plagued coaches manufactured about this time.

Bob,

I wouldn't call this a scam. More likely this is a case of the repair facility not knowing exactly what the problem is and they are "Easter Egging" it, doing the "hunt and peck" method of troubleshooting hoping they will luck onto the problem. Hopefully you can find a shop that can be of help. The best way to find it is to wait until a hard failure then troubleshoot it. Just because the engine warning light comes on doesn't mean it will self destruct in 30 seconds. Has the repair shop read the fault codes on the engine computer?

I really never thought the deal was a scam. I have experience with this Cummins facility and have always been treated fairly. The ecm generated a fault code pointing to the fuel pressure sensor. When they replaced the sensor fault did not go away. Then they found melted wires in the engine wiring harness. Replaced the harness, but then the engine wouldn't start. That was about May 3. Since then they have been trying to figure out where the problems is. I went to the shop today, pointed them to the wiring diagrams and tried to trace the ignition circuit since the Cummins wiring harness was not getting voltage when the key was turned. All fuses we could find were okay.
After stewing about it for a couple of hours, I decided to ask the obvious question - had anyone checked the emergency cut off switch? Getting blank looks, I walked over to the coach and found that the switch had been tripped!! Somebody probably elbowed it when replacing the wiring harness. Coach started right up after re-setting the switch. Nothing better than a bunch of chagrined techs!!!! Lord knows how many hours they sunk into trouble shooting the problem.

Remaining problem is we don't know what caused the fried wiring harness in the first place.

Glad to hear you are underway again. Having been in the electronics field for a few years, I can say that sometimes things happen that cannot be explained, such as the melted wires. Once corrected, things operate normaly. It could have been caused by a connector that was not seated properly and during the replacement of parts, it got pushed together and now, no more problems. Hopefully it will never happen again and all will be well.
