So been battling a gremlin all season. The basics are the 8.1S with Smartview (manufactured in 2005) in a 2005 DA390.
Sympoms: Intermittently and at random, will get a single beep like ignition turned on or off, and engine will momentarily stumble on starboard engine. (problem is not issue with Port...yet) (if at lower RPM say 1000, will come back at idle (680-700)) if at higher RPM, loss of power for quicker than you read this, and comes back to life. Smartview looses connection, then 50% will come back as normal, other 50% time will have total loss of insturments for that motor. Seems to settle for a bit, then comes back with a single beep and may regain instruementation and start the process over.
So far, all connections on harness, ground, battery checked and no corrision and reset.
Voltage readings on smartview and vesselview range from 13.5 to 14.1
New 50 CB installed (red button, not yellow one)
Ran this morning with Merc Tech, and when happens, laptop still receives data, no loss of communication on CanBus...
.
Installed Vesselview mobile (had one laying around) and no loss of communication of engine data, even during the beep and stumble.
NO FAULT CODES, so it has to be in the electrical supply side right?
This has my completely stumped, and like many searched and searched forums, so will use this to update as my search continues. Seems quite a few had this issue, but no one posted a resolution. My plan is to do that or loose my sanity... whichever comes first!
