Mdc??

I just purchased a 2001 x star a few months ago and I have a new mdc to go in it. Just went to install it and the water tube is hooked into the secondary pitot, nothing on the primary side. Is this correct?

There should be two tubes for the MDC. Does the new boat have perfect pass or something that would eliminate the use of the primary tube?

My guess would be that someone put Perfect Pass on the boat which would take the place of one (the primary) of the speedos. That would leave you with the secondary one. My suggestion would be to scrap the second speedo and replace it with a GPS speedo. The reason I say this is 9 times out of 10 water from the pito tube is the what caused the failure in the first place. Depending on your MCOCD PP makes a GPS speedo but it's pricey at $350

There are tons of other options starting at about $125 but then you get into that mixed bag of gauges look which depending on your taste you may not want.

Another option is to replace the 2nd speedo with a marine head unit. There are quite a few out there, and in my opinion it is a better place to have a radio head unit in most boats than where they put them.

I picked one up for when I redo my dash as the factory MC location for the radio has the aux cords connected in the driver footwell or where you have to get out of the seat.

The boat does have perfect pass installed. I changed the mdc and my gauges are still
Not working. All light up as they should but still only the tach and speedo work.

Possible a connection after the MDC. Its a pain in the butt but you may want to clean the connections with starter fluid (many threads on what to use). It is my understanding that if one connection is bad it will trip all of the gauges since it is an inline series network. I do not know the exact technical term for it. Basically if one is not working none will work. Just my understanding.

Did this this occur after winter start up or did it happen after working correctly with no changes to power/battery connections? Your PD will be different with each.

If after winter start up, get real serious about tracking the power cables and ground to ensure everything is connected correctly. Miss a ground or power cable and your results will vary.

If it has been happened with no power changes, there's a good chance one of the gauges is bad causing the other to malfunction as well. The system runs on a (poorly implemented) serial digital bus typology. This means that one malfunctioning gauge can effect the others on the bus. Try disconnecting one gauge at a time and see if the symptoms change. If that doesn't work you can always go the other direction and disconnect all but one of the gauges and see if that one works. You my want to try this a couple times in case you pick the broken gauge or you have multiple gauges that are bad.

I've written several long posts on trouble shooting and my personal opinions on this system so I'll spare everyone another rant on the subject. Good luck with your challenge, hopefully you just missed a ground or power cable after putting the boat back in service.

Do you have any idea if they still offer the original style gauges. I’m thinking my fuel gauge is the problem.

mcpartsdepot is where to look. to save a lot of $$ look on greatlakesskipper, you may find something there. FWIW hava you checked the sender from the tank? they are notorious for not working.
