    • Converting 6B5.9M from 12 to 24 volts

      This topic has 2 replies, has 3 voices, and was last updated by Tony Athens 6 hours ago

      December 18, 2018 at 3:40 am My 6B5.9M was manufactured in 1994 but installed new in 2004 in my sailboat. I’m now converting my electrical system to 24volts and was originally planning to just swap out the alternator and leave the rest of the relatively simple engine electrical systems at 12V. However, as it turns out only a few electronics items need 12V and a simple DCDC converter can handle them nicely. In many ways it would be simpler to convert all to 24V, but h…

      December 18, 2018 at 8:03 am Robert, I really think you need to rethink this out if $$, time, complexity & and hassle are part of what you’d like to keep at a minimum.. 1) Converting the panels is not cheap-The 24VDC PC board will set you back over $300 each. Then you have the lights and the tach. 2) You need a new starter, new mag switch, and a new fuel solenoid 3) then the new alternator……. Way better and easier to go exactly the other way.. Go ah…

    • Murphy Gauge on 6BTA

      November 30, 2018 at 4:49 pm Anybody have pics of these installed on a 6bta? I seen the 6cta (I think) on this site but it looks like the tank might be bigger. I’d like to put them on the sides just like that though. How’s installation? I need to put fitting in the bottom the the tank and then the top one can go over to the starboard side of the tank where all of the plugs are?

      November 26, 2018 at 4:42 am Hi all, I have a pair of recently installed QSB5.9 380hp with Vessel View 4’s. Troll mode has been displayed in yellow with (apparently no operational effect ) since installation. When I try to disable it, the disable button is greyed out. When the engines were commissioned, the Cummins Tech noticed this, but brushed it off.

      November 14, 2018 at 11:31 am The Cummins OEM analog marine panel on my trawler has one blank VDO gauge space that I want to use for a combination boost/pyro gauge. The hole size for the ISSPRO SMX Marine Boost/Pyro (EGT) Turbocator Gauge Kit is too large for the VDO gauge space. I have been unable to find this combination in a VDO gauge. Any suggestions?

      May 18, 2017 at 10:43 am Hello Everyone. Lately I have been getting an alarm on my QSB 5.9 which reads “ECM High Battery Volts”. This alarm is intermittent and sounds everyday but does not last all day. Comes and goes when it feels like. Has anyone had any experience with this alarm?

    • Chasing down jumpy gauges – protecting connections.

      This topic has 5 replies, has 3 voices, and was last updated by Paul Hoffman 2 months ago

      September 19, 2018 at 6:49 am 1999 Cummings 6BTA 5.9 M-3. I’m chasing oil gauge issues on both engines. At low RPMs (<1,000) no issues, all gauges indicate rock steady. When pushing up to say 2,000 one or both gauges will start to swing erratically, and eventually fall to zero. This typically leads to an engine alarm in a few minutes (though not always – not sure why). Jogging the throttles to bring RPMs up and down tends to bring the gauges off the zero,…

    • Vessel View works, dash gauges don't after install

      September 21, 2018 at 9:45 am Hi, I recently installed a VesselView 4 into my 2007 SeaRay, replacing the dead DieselView unit. I unplugged the wiring harness from the command module and connected the 403 harness in its place. The 403 works great but at the same time, all my dash gauges stopped working. Does the cable I disconnected need to connect to something else? Many thanks in advance for anyone who takes the time to point this newbie in the right direction. Brian

      September 21, 2018 at 11:02 am An update on this. If I reconnect the harness for DieselView to the j-box and connect the cables to it, the dash gauges work again. Obviously, this isn’t a great solution as I want to toss the DieselView unit. Do I need to terminate either or both of the connectors (shown in pic) going into DieselView?

      September 3, 2018 at 2:55 am HI everyone, I am pretty much new to power boating; so you can guess I do not know much about engines and instrumentation. Everything was running smoothly until I had my engines serviced. When I start them the RPM tachometer for one engine fluctuates wildly from 600 to 2000 RPM, also under load. The engine runs fine. I have ruled out a faulty tachometer because the one in the boat and the one on the flybridge are doing the same thing. Has anyb…

      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
