Tom/Barb,
Thank you, thank you. I was able to return to "square one" on diagnosing the overcharging alternator problem, by following your instructions on how to try disconnecting the chassis battery, etc. All the dashboard lights returned to normal, the engine started, everything fine except for my original alternator problem (showing constant 15 volt charge rate).
I will treasure this "nugget" of information that you gave me. NONE of my Spartan, nor Newmar manuals had any of this information. Not even anything about the little red warning light in every round gauge. This info will make me feel a lot more secure regarding getting stranded somewhere,....which has never happened with this Dutch Star. Thanks again.
I was having problems getting started and removed all my batteries to test, clean and charge them. After reinstalling I found the codes kept in my ECM were gone. ( I have a "road Tech" computer on board) I asked Cummins about this and their answer was the ECM must have power to retain the trouble shooting codes.
So, when the batteries are removed the ECM forgets the code that is preventing the computer to allow the start.
The problem will return if not corrected, and the computer will also forget the codes that know how you drive, and will start the 1500 mile cycle to reinstall the drive codes.
