2015 wedge calibration

Recommended Posts

ChainSetter

I just got a 2015 247 dealer demo 1.1 hours.  Every thing seemed to be working until I turned off auto wedge ( it was giving high speed wedge warnigs over 25mph) Now the wedge is all screwed up.  It tells me to check wedge calibration but there is no option for that.  Under power wedge on the MTC screen it only has an option for auto wedge on or off.  It is unresponsive to the sport knob.  It sometimes moves with the dash touch screen switch but won't stow completely and asks for calibration

My 2016 23 lsv did the same thing after using the wedge a few times. We were a long way from the marina, so I just continued and knew any problem would be covered by warranty plus I was not aware of any wedge calibration. Eventually it quit doing it and I didn't do anything but just ignore the warnings. I was receiving the message about every 5 -10 minutes probably at least a dozen times before it stopped popping up on my screen.

I also remember it didn't want to stow, but finally did. When I was receiving the same warning, I knew the wedge was stowed so I just didn't worry about the warnings.  I haven't had any problems since.

Do you remember how many hours it took to go back to normal?

Cycle it through its limits. Full stowed to full down and back. Fixed mine.

Go to the settings menu on your 7 inch screen, select debug assist and put the wedge all the way down (to the lift position) using the controls on the 12 inch screen, joystick pad or using the minus icon on the debug assist screen.  The wedge voltage should be 0.51 to 0.53 with wedge down.  To adjust, losen the two screws on the sensor on the starboard wedge arm and pivot the sensor to change the voltage on the debug screen. Tighen the screws when it is in the correct range.  If the bolt under the sensor is loose, it may need to be tightened so the sensor adjustment will not vary.  The wedge can be lifted using the plus icon on the debug screen.

Cleaver you have got to be a Malibu tech or something that was awesome! Seems to have fixed my issue for now. You have no idea  how much trouble you have saved me. Thanks!!! Any idea why auto bilge keeps flashing when there is no water in the bilge?

Well it was fixed. We got the calibration set and it worked for about a week. All the sudden today it won't go down. No alarms but I can't even get it to move down in the debug screen. The wedge is sitting all the way up. I can hit the plus sign and I hear the hydraulic go for a half second. Minus does nothing nor does the on screen control or the joystick. Any more ideas? Also checked the 5 amp fuse under the dash and reset the 40 amp by the motor.

The fuse boxes under the dash has a wedge up and wedge down fuse.  Each has a bypass position next to the fuse.  If you insert a good fuse into the bypass position for wedge down, it should move.  The fuse cover has the fuse position and bypass position number on it that corresponds to the correct position on the fuse board. The power button must be on and fuse box led blinking.  If it does not move, there may be a wiring, connection or power/fuse box issue.  If it moves, you may have an issue with the 7 inch viper 2.  Is your debug screen wedge position at 200 and voltage near 3.5 when the wedge is up? 

See if the date tag on the back of your 7 inch viper 2 is between 02/06/15 to 07/31/15.  Some of them had issues and your dealer can help you with it.

Check the reddish bypass valve on the top of the cylinder to make sure it is tight.

@csleaver I have the 200 and 3.5 when the wedge is up. What do I do?

The debug assist screen should read 199 to 200 and 3.50 to 3.60 V when the wedge is all the way up in the stow position and it should read 0 to 1 and 0.50 to 0.53 V when the wedge is in the full down lift position.

Is that what yours is reading?

The '+' and '-' icons on the debug assist screen can be used to lift or lower the wedge for testing.  The wedge will go up a little each time you touch +, and down a little each time you touch -. 

If the wedge does not move, first check the wedge breaker which should be in the engine compartment under the center rear cockpit seat.  Otherwise, there may be a faulty or loose connector, plug, breaker, wire, relay pack, viper screen, a problem with the actuator, or a more physical problem with the wedge like a broken or missing fastener.

Mine reads 200 and 3.5-3.6 in both the up and down position. I’m able to Move it up and down with the (-) &(+) buttons. The fuses are both good. It was working fine until I took the wedge off to have some of the cracks welded. I’ve tried adjusting the sensor but with no luck. Anything else I can try? It’s 4 weeks before I can get it into the closet boat shop.

There is a bolt with a magnet in it behind the wedge sensor, make sure it is installed correctly, and tight enough that it does not spin on its own.  If it has moved, you may need to rotate it to a position that will allow you to move the sensor into the correct adjustment voltage range.

I did not realize that the bolt had a magnet in it. My bolt stripped and I just replaced it with a 2.5in stainless bolt. I’m having a hard tome finding it online and the local boat shop says 2-3weeks. Any ideas?

I don't know where you would get one from, other than a Malibu dealer.
