ISC330 + 350 Oil Pressure Sensor /Sender info

Yahoo Message Number: 2108
Fred, thanks for your assist about the coach's many sensors, etc. + directing me to Doug Rutherford. This kind of help confirms that we bought the right coach / mfg.

"Bluechow" did a great job of describing his engines symptoms, allowing Doug to zero in and we to learn. We're about to head up to CC/JC, then to Alaska, and don't want a SENSOR prob. in the Yukon.

This may be of interest to the Group.......Don

Hi Don. Well from what we can tell, the "oil sensor" you are inquiring about is definitely the Cummins oil pressure "sender." It has to be the Cummins sender unit, because the tech found it with the lap top.

Country Coach senders are analog and can not be accessed or trouble- shot with software. Cummins did in fact have an issue with the oil pressure senders on the 330 & 350 ISC engines.
The block breather is probably what we would refer to as the crankcase vent. The one that was replaced was on a 2000 model year coach. Cummins has not been having problems on later model years with the crankcase vent as far as I know, so I don't think you have anything to worry about on that front.

I have included the text of an email response below from my electrical man on the Silverleaf and battery discharge questions.
Hope this helps. If you have any other questions, feel free to drop us a line. "SilverLeaf manufactures a wide range of products it is the VMS200 that is referred to below. This unit monitors and displays information that is available on a two wire 'twisted pair' network used to communicate data between the engine computer, transmission computer and ABS/ATC etc. The VMS200 does not use any hard wired sensors therefore the information it displays such as oil pressure is sourced directly from the engine computer etc. The oil temperature sensor is not standard but can be installed at any Cummins dealer.
SilverLeaf's web site is www.simply-smarter.com
All batteries will 'self discharge' over time at a rate dependent on battery condition and temperature. With wet cell or Lead acid battery technology, you can see the battery self-discharge completely in less than two months.

If left discharged too long, a lead crystal will grow internally and cause permanent damage. It is important to clean the top of any battery regularly to prevent a current path across whatever residues may exist between the battery posts.
Additionally, the disconnect switch does not disconnect all loads. The inverter will still receive power so it is important to turn it off also to minimize current draw, and a 'memory circuit' will remain powered up to maintain settings on radios etc."
