No Power to Power Gear Hydraulic Levelers

Yahoo Message Number: 78322
We have studied the Power Gear manuals and the Country Coach wiring diagrams until I'm cross-eyed and haven't found my problem. I do NOT have 12 volts at pin #5 of the Power Gear Control Box. I see the pin is fed by wire #68 from chassis/ignition fuse panel. The fuse is good and has power, the entry step is working and have checked continuity of the fuse. I assume there is a relay in the circuit but not sure and am unable to find which relay to inspect. Guess it could be the signal from the ignition switch, should be able to figure that out when I find the relay.

Can anyone help point me in the right direction?
The coach was in for service at the local Cat dealer, the levelers were working when it went in and didn't when it came back. They performed the heater hose re-route service bulletin and put the latest ECM program in. Good news is, it runs great and the OTR heat now works very well.

Thanks for any help you can offer,

Dale:

What heater hose re-route service bulletin? Can you elaborate? TIA

Gil,

It is an old "Service Letter" that was never applied to our coach. Here is what the ticket says: "PS41792 for Country Coach motor homes that have little or no heat from cab heater. Cab heater return line needs to be moved from thermostat housing to water pump inlet to increase flow to cab heater."

Re: [Country-Coach-Owners] No Power to Power Gear Hydraulic LevelersDale,
Thanks for all of the information you've written. We have an 06 Inspire, and I don't think I've read or know about a CAT service bulletin for the hose re-route. I'd be grateful to hear about that though of course there could be something different between an 05 and an 06. Regarding tires, we replaced our tires almost 2 years ago in MN with the 295s Bridgestone and have been satisfied with them. We had about 65,000 when we replaced them. My concern was as yours is to get some extra load capacity and also to eliminate the front tire wear that we got with the Goodyears.

Thanks in advance.

Dale, years ago I had a ground to the levelers go bad. It is located somewhere near the firewall in front of the driver's feet, accessible through the generator door.
(Were the CAT techs working in the generator compartment?)

My symptom was uncommanded retraction of the levelers.
Voltage was still provided to the system, but only about 10 volts. Cleaning the connection fixed it.
I don't know where this ground is in the system, but it might be worth a look.

Well, I finally figured it out, kind of embarrassing... It was a fuse. The fuse was the first thing I checked but learned an important lesson, don't count the wiring diagrams in the manual as gospel. The diagrams indicate the levelers are fused in a different position than they actually are.
The good thing is I learned a lot about the coach digging around trying to find the problem.

Thanks to everyone for the suggestions!
