Engine Instrument Shutdown - HELP!

[fep]

After being on the road for 1-2 hours,all the engine gauges, Tach, Speedometer go to zero and the "Christmas Tree" (annunciator panel) blinks on/off and buzzes. The engine remains running. After re start everything is OK, but at some shorter interval it all repeats - suggesting a heat buildup condition. Installed a new Christmas Tree, checked all battery connections,loose wires - no help. Driven it 1800 miles like this.Alpine '04 34'FDDS Help!

Hi fep,

Welcome to the Forum!! I see no one has posted any helpful suggestions, and unfortunately, I don't have any other than asking whether you have called the factory. Call 866-567-4133, which is the customer service number. If you don't get help fairly quickly, call back and ask for Mike Glazier, who is the head of customer service.

Good luck!!

Thank you for your concern and your reply. Idid call WRV (Mark) who suggested the replacement of the Christmas Tree - which I did to no avail.I paid $330.for that item, and even though it isn't the solution, WRV won't take it back because it is an electric component.I'll call Glazier - perhaps he can help. Electrical glitches are difficult to analyze.I appreciate your concern. Frank Punderson

First thing I would do is take it to the closest Cummins dealer and have them read the engine computer for an error. That might just give you the reason for the failure.

HI FEP - We had the same thing happen on our '03 and after 3 months we finally diagnosed that it was the Computer Brain for the dash that was back by (in front of & underneath)the battery compartment. I just looked at the repair order & it is called the Vehicle Data Computer but does not list Part #. We actually took our coach to Butlers in Yakima and had it replaced there under extended warranty.

Dear Swans: God bless you for responding and also having the solution! I've ordered one from WRV and will have it installed. Electrical difficulties are a problem to identify. I sure hope this turns out to be our solution. Ours is a 34' '04, and this is the first real difficulty we have experienced. Many, many thanksfor your input. Frank Punderson
