2015 242 LS - Tach's not working and Connext screen on white home screen

[Kirtis Bergen]

Anyone have a fix for this one or suggestions.

House battery died on one of the last trips out so replaced both with new batteries.

When powered everything back up and started up the boat the Tach's will not spin up and the Connext screen stays in the start up "White Yamaha" screen. The tach does a little bounce but none of the loud beep or Port tach full dial over when the key is turned on. Both motors fire up great and boat runs with no problems. Every year we have taken the batteries out for the winter and reinstalled with no issues

Tested both the power to the tach and the Connext and they are full 12.6v at the plug so no issues on power. Have read the Port tach controls the start up of the electronics and read here on the threads that someone had the same issue and replaced the screen but did not resolve the issue, only replacing the Port Tach did?

Have a Hydrophase cruise controller and its picking up all the motor info it always has since I put it in the boat the first year so know all the motor computers are working with no issue.

Anyone replace the Port tach and fix the issue or any suggestions on a test of fix on this? Can the computer be rebooted at the dealer? Heard the Port tach is not available or hard to get?

Pics are with the boat running.

Thats where i saw it.
Ypu could have gotten a voltage spike with the battery change and fried the tach or connext.
Not sure which tach is the main i believe it has the extra plug going to it.

the port tach is the main….2 main plugs and then a jumper plug over to the starboard tach.

Makes sense for the tach getting a spike maybe when the house battery died…you can hear the faint motor noise and it shakes a bit but won’t roll over.

Any ideas how to test to see and what the ratings should be for the tach. Sounds like they are tough to get a replacement

Oem says unavailable which is total bullshit. I looked into it for my 16 ar240 and same thing. Discontinued on a 9 year old boat is crap. Dont know if there is other options out there. Do a search here in the classifieds there was a part out of a 2017 ar240 maybe those are still available

I saw the unavailable online made me cringe….seems to be a critical piece that fires the whole system up including the connext from what I have gleamed from different threads and reading. Hard to believe they stopped making replacements for such a critical piece.

Just dm’d a guy who is parting out his boat so hopefully. Otherwise will see if the dealer has any options to test to be a 100% sure and maybe can find a shop to rebuild.

Thanks

They appear to primarily repair/replace the LCD screens, but they might be able to remedy the issue.

Yes, totally agree that Yamaha has made it very expensive and difficult to source a critical component which is unacceptable. It’s not only the tachs, but the older connext screens as well which are extremely expense to source.

I have checked with them weeks ago. They only repair the lcds and lenses. Unfortunately they dont repair the circuit board. They verify power and ground thats it
