I am currently looking to join the Prevost ownership club. I am currently looking at a 2000 CC that has had the original Compudigital dash replaced with the solid state Silver Leaf VMS 640CL Glass Dash. Does anybody have any experience with this upgrade? Any feedback on its reliability would be appreciated. Looking forward to Prevost ownership.
I have a 99 CC that I replaced the digital dash in about four years ago. Not a single problem so far. Love it. Martin and Dale are great people to work with.
Thanks for the response/feedback.
I just upgraded my dash this spring. Like it very well so far with only one complaint. The fuel gauge is way off. Have been supplied the calibration procedure but that requires running the fuel tank down to some point that one would call zero [1/4 or so] and I haven't driven enough to reach that point.
BUDDY, did you have issues with your fuel readings??
That's a $10K upgrade! I'm upgrading mine in two weeks. You should feel good knowing the PC based system has been replaced.
My fule gauge does not work. It has never been correct and does not even read as you use your fuel while driving. Have changed the fuel gauge parameters with my computer till I am tired of fooling with it. I have installed a manual Prevost fuel gauge under the dash and connected a wire from the gauge to pin 68 in the drivers compartment along with power and ground. (24 volt gauge). This is the only problem I have with the system. Dale, Martin and I have gone round and round about this. Good luck. If you use the manual gauge you have to disconnect the fuel gauge wire Silver Leaf uses for the manual gauge to work. In my coach it is wire #34 in the steer compartment.
Charles,
Can you be more specific on where pin 68 is located?
Thanks,
Charles, I also heard the Silver Leaf dash does not include a Turbo Boost Guage. Is this true or is it some other guage that is not included.
Mine does have a turbo boost gauge. There are some functions the Silver Leaf will not show only because of the differences in the information or the messages the DDEC's send out. Not a Silver Leaf problem.
Pin 68 is located outside above the steer compartment in the upper compartment. on my 99, there is a bank of about 75 or so brass screws that all the various wires go to. They are all numbered. On your coach please verify that pin 68 is the wire coming from the fuel gauge sending unit. It puts out OHMs readings. I don't think the configuration on the 2000 is any different than on my 99. The 68 goes to the back of the fuel gauge, another terminal on the gauge is marked ground and the third is marked +Voltage (24 volt). I made up a wire harness with all three wires and used a 24V terminal and a ground terminal in the same compartment as the 68 terminal. Find a 24V source that comes on with the ignition key so the gauge is not hot all the time.
I had Dale install the replacement dash in my 2002 CC a few years ago (4?) and have had the same problem with the fuel gauge reading full for the first 550-600 miles after fillup, as I had with the Compudigital Dash. Checked the sender a couple of times, but I have heard that the problem is the plastic fuel tank, which gets hot from the return fuel from the engine, and sags at the top surface where the sender is mounted, allowing the sender to sink in the tank, relative to the fuel level, and give a false reading. This distortion is permanent, and am told it did not happen in earlier models when the tank was not plastic.
BTW, I do have a turbo boost readout; it was also present on the Compudigital from CC.
