    • Sender Questions for 6BTA

      This topic has 2 replies, has 2 voices, and was last updated byZac Schramm 2 weeks ago

      March 3, 2024 at 9:12 am Hi, I am testing the sensors on my engine and curious about 2 things. 1. Is there any reason a standard resistive (oil pressure) sender can’t also be used to measure boost air pressure? It should just be a diaphragm inside and in which case air and oil should be similar.  I already have 2 of these on hand and I want to use the actisense emu-1 to read and it requires resistive senders and I mostly find only transducers for boost pressure.  …

      March 3, 2024 at 7:38 pm Thank you Tony. Boost – Thank you, I was going to select a lower scale (80 psi) sensor. Water temp – Yes that is what it looks like.  I can’t find any technical information or datasheet on it. -Z

      February 6, 2024 at 7:11 am High probability that it is there already.  We have 2004 vintage 6CTA’s and they were conveniently on the top of the flange from an orientation perspective.  I could not get the plugs to budge so I had our mechanic remove the plugs and then I did the install of the probe.  Go take a look at the flange that mates the turbo out and the exhaust elbow.

      January 17, 2024 at 5:45 pm Have two (2) 6BTA5.9M2 marine engines with dealer installed VDO 0- 250 deg. F two- wire electric analog helm gauges. I know these type gauges are not high accuracy, but these are way off. Heat gun reading the sender base (and reading the accessible coolant areas will show 178-184 degrees and the gauge reads 205 (same both engines). My factory wiring diagram for these engines (12-v) shows positive battery voltage to starter solenoid, circuit brea…

      December 14, 2023 at 11:46 pm Hey guys I’ve got the original SC5000 engine screens on my 2006 Tiara and they are pretty much toast. I’m trying to get the SmartCraft Connect Gateway that allows me to push all that data to some dedicated 7″ Raymarine Axioms instead and I’m trying to see if it’s possible. It appears the way my gauges are wired I have 2x Single SmartCraft junction boxes instead of 1x Dual engine box. Does that mean I will need to ge…

      December 31, 2023 at 12:15 pm I am sorry I missed this posting! I had a 2006 Tiara Sovran  with QSCs that this was done to before my purchase. I needed to replace the gateway during ownership (which came from SBM) and it had one gateway sending both engine’s data to a Raymarine ES 127 mfd via the setalkng bone. It worked great!
