      May 31, 2017 at 12:21 pm These panels [370HP Diamond CPL 2208], have a loose circuit board associated with each engine panel at each control station. An alarm buzzer is part of each board. The ‘workings’ of this board tion. The ‘workings’ of this board are a mystery to me as I can’t find documentation. According to the first attachment the volt meter has purple [ignition] on one side and purple/black thru the low volt LED thence to a two w…

      Reply #9 October 29, 2017 at 12:36 pm This may also add to the understanding of the factory system…………..The PCB boat IS NOT needed for all the instrument to work properly. In fact, on a properly working system, the PCB can be removed from the panel and all of the instrument will operate as they should.. The PCB BOARD is there for one reason only–To have an “vital sign alarm system” for the engine.. It basically reads the return signal from t…

      July 10, 2017 at 12:00 pm I’ve installed Faria Synchronizers (Catalog #34601, Factory #SY9671) on my Cummins 6BTA-3M powered boat. So far, the synchronizers aren’t working as the needle/indicator jumps and I’ve tried to adjust the synchronizers per the instructions, no help/progress. Are the engines equipped with a magnetic or alternator tach. signal source…? Any idea’s..? Thank you..

      July 22, 2017 at 5:10 pm Cummins had to replace my QSB 5.9 engine and put a Recon in it this last week. All seems to be fine. They very nicely gave me a version 3 VesselView as I didn’t have one in the boat. We connected it for the sea trial and it all worked fine yesterday. Today, shortly after starting the engine I got the “sim no J39 data” error. When this occurs, don’t get any rpm reading, either on the VesselView or the original tachome…

I don’t have that harness, only the VesselView harness. Is the Vessel View Adaptor Harness something that can help resolve this issue? If I can find one…

It looks like the non starting on the stb engine was due to the hp plungers on the fuel pump being stuck in due to being storage for years. I explains why the fuel rail had no fuel I guess.

You can see in this pic I have on my genset an unused coolant port right next to the coolant switch.  What you have now are “switches” that are either open or closed to trigger the safety shutdown. What you will be adding are sending units which will provide the ohm readings for the gauges.  Rob "Luck is the residue of good design." Attachments:You must be logged in to access attached files.
