    • Smart craft needs calabration

      April 16, 2018 at 12:07 pm I own a 2005 searay 39 dancer with cummins 370’s. While under way with engine syncs on, (only using starboard throttle) lost port rpm, switched off syncs, used both trottles ok. Traced to broken wire in harness connector under starboard aftercooler. Engine syncs now work. When i start engines, smart craft says(must perform dielsel calibration). I tried to calibrate will not let me. If I turn start rocker switch on& off 1 time quickly, …

    • SMX Digital 6CTA external alarm

      This topic has 6 replies, has 3 voices, and was last updated by Corey Schmidt 1 month ago

      March 14, 2018 at 4:32 pm I want to hook up an external alarm to the SMX Digital View display for my Cummins 6CTA 8.3. From the webpage it looks like the alarm lead closes to ground when there is an alarm. Can I hook that lead (pin3) up to an external buzzer ground and run a fused positive lead to the positive end of the buzzer? Thanks

      Reply #6 March 17, 2018 at 9:31 am I see, yes you are correct that the panel set points for the ED-1/ED-X display on a 480CE cannot be changed because that set-point number is determined by the engine ECM controller… not the display. Think of your display as a “monitor” and nothing else. The displays we use (SMX DigitalView) to indicate instrumentation on mechanical engines uses software that Seaboard developed in-house and therefore we have much more flexibilit…

    • Is an EGT alarm a better overheat indicator than coolent temp.

      This topic has 12 replies, has 7 voices, and was last updated by Dan 2 months ago

      January 28, 2018 at 5:10 pm I’m considering installing EGT gauges with alarms to augment my coolent temp gauges/alarms. I’m thinking this is an overall better heads up that things are heating up. I’ve read that if you lost all coolant (blown hose) you may not get an alarm due to sensors no longer submerged in coolant. Am I thinking corectly? Is it worth installing these? Any strong opinions? Thanks! Joe

The one that failed was the one that picked up the oyster shell, damage was probably done then.

    • Bosch K1 Alternator wiring

      This topic has 8 replies, has 2 voices, and was last updated by Tony Athens 2 months ago

      January 3, 2018 at 9:45 pm What is the D+ lug on the K1 Bosch alternator for? It was jumped over from the B+ lug when I inherited this boat. It had a parasitic drain on the battery that was identified as the alternator. First suspicions and advise was that a diode was bad. But, I am now thinking the jumper wire from the D+ lug was the cause. I “now” understand this to be the field exciting lug also used in conjunction with a charge indicator light. The light f…

      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…

      November 25, 2017 at 3:38 pm I’m about to install a pair of SMX Digital Voltmeters to a pair of 8Ds. I’m installing home runs +/- for both but…… Both batteries go to a common ground bus, from which the whole boat is grounded. Is there any value to having one of the DVMs have a switched negative which goes to the ground bus so I can see the difference between battery egatuve and ground negative?
