I went out to run the coach today. No gauges! Here is a list of what is not working:
RPM, Oil press, Water temp, Engine volts, Fuel Tach, Fuel gauge (neither main or aux.), Also the Check Engine and Stop Engine lights don't flash when turn on ignition.
Also in the rear electrical panel in passenger side engine compartment there are two breakers for the DDEC power. I reset both of them, but only one worked. It looked like the one closest to the engine would not reset. The engine would only run about 300 rpm and was blowing black smoke. I replaced that breaker with a 20amp auto-reset breaker and now the engine starts and seems to run ok.
VMSpc does receive info from the computer so I'm getting water temp, engine volts, rpm, oil press, turbo boost.
But I still don't have any gauges! Can't see any wires loose or connectors loose. Funny that they all stopped working at the same time.
Any ideas?
