Tilt indicator on CLink not working

[jackmanjls]

This is a boat that I just bought.

I have the square command link (CLink) on a F90TLR 2006 but mfg date is 11/05 so many of the items that I fixed have been 2005 parts.

The CLink Tach tilt indicator is always on 1 bar. Manually moving the tilt bar up/down has not affect at the CLink.

I checked the resistance on the tilt sensor at the motors plug and get between 5-200 ohms. That seems to be reasonable.

I reseated and inspected all the plug connections and they all look good.

At this point the issue is pointing towards either the wiring or the gauge. When first turned on the gauge does go all the way to the top and then comes back down when the turn on procedure is complete. This might indicate that the CLink is OK.

I'm looking for ideas on what I can do to further troubleshoot this. Any suggestion on where to get a wiring diagram.

make sure the two pink wires with white caps are connected to each other.
they will be located around the engine 10 pin main connector.
6y5 they are dissconected,6y8 they need to be or you get what you got.
its actually in the rigging guide.

I looked for the 2 pink wires and can't find.

When you talk about the "rigging manual" I'm assuming you mean the installation manual. If that's the case I've searched/found some of the online install manuals and there's no mention of the 2 pink wires.

On my F90TLR there's the trim sensor that's next to a 10-pin connector. I looked around that area and can't see the 2 pink wires.

Can you give me any additional ideas on how I can find these wires?

[rodbolt17]

single pink wires,white waterproof caps, typically taped to the harness with yellow or white tape.

[jackmanjls]

Down by the dipstick there are 2 pink wires with white caps that are taped together with yellow tape. Each wire is in a black protective sheath. These gotta be the wires.

Each cap looks like it has a plug on the end. Do I remove this plug and jumper the 2 wires together? Should I send you a pic for verification? I don't want to harm the ECM by shorting wires together.

P.S. You've been a great help

Also what do they call the plastic stationary bracket that the tilt sensor arm rides on. Mine is broken and I need to order another.

Its called a "cam trim sender". If yours was plastic, I know on my F150, mine also broke. They updated the part to a steel part and likely won't break again.

If you look up in the parts section here on the forum, put in your engine information, it should be under BRACKET 1 or in my case, bracket 2


I just looked up your motor parts fisch. I don't see that part at all listed. BRACKET2 shows the switch itself but not the "cam trim sender" which is what's on my 150, sorry, dunno..

Can you respond to my post #5, you probably only looked at my last post and I sent 2 posts.

Is this for me???

Well, anyway even if it isn't, can you pull the sender switch off the engine, turn in the ignition and just manually move the switch and watch the dash gauge and see if it affects it?

Is it possible what ever tab that comes out of the switch is broken? Being the dash gauge goes up and down at "initial turn on" sounds like thats functioning correctly.

Right from the start here's what I did. When reading keep in mind that I bought this boat/motor used so I have no idea of the history.

Originally I noticed that the clink tilt was reading max, all bars were lit up. I tried the TT and theres was no movement. I searched around and found that I could set the tilt=0 so, I trimmed the motor down and when thru the set tilt=0 process. The bars came down to 1 showing but still no TT when moving the motor tilt.

I then turned my attention to the tilt sensor and found that the tilt sensor was stuck all the way to the top. I took the tile sensor off the motor and freed up the tilt cam so it would easily. I figured this was the solution all will be resolved. I plugged back into the motor, turned on the key and the clink tilt didn't move. I then reset the tilt=0 thinking that was an issue...no luck, still no reading.

I then got the ohm meter (along with the old lady) and moved the trim cam arm up/down. I got reading from about 5-200 ohms. I conclude that the tilt sensor is OK.

In addition, I've noticed that when I turn the key on the trim indicator goes up/down indicating a sign of life. Also, when I zero the tilt the indicator goes up/down. I'm concluding that this up/down is a sign that the clink is still alive.

After looking at a electrical diagram the output of the tilt sensor is sent to the ECM and then onto the gauge. I think the ECM is OK b/c there's no other indicators that are malfunctioning.

Now I read your email about 2 pink wires. I found the wires and they aren't shorted together. If I jumper these wires together I afraid it might harm the ECM.

Based on what I've explained do you have any other ideas?

I'll watch my email for your response.

Rodbolt17 is a master Yamaha tech, I would follow his directions on this,

Do you realize this is a forum and not e mail?
You can tell who writes the different posts by looking at the upper left of the post

[rodbolt17]

if you remove the caps on both pink connectors SURPRISE one is female the other male.
unplugged and it signals a digital 6y5 style tach trim indicate.
plugged together it changes the signal to route through the ECU and placed on the can line to the buss.
on the parts microfice its bracket two reference 4 and 5.

Brilliant

In the end I took rodbolt17's wisdom and applied it to my Yamie F90TLR.

It's important to note that if you have the tilt sensor disconnected from the motor, as I did, and connecting the 2 pink wires for the 6Y8 CLink data to be sent to the ECM that I did not get a reading right away.

How I did get a reading was to crank the arm on the tilt sensor all the way to one side (highest arm resistance) and then recal the CLink to trim=0. At that point moving the cam arm up/down caused the indicator to respond accordingly.

This task is officially done and can cross off my list. Thanks to all involved.
