Spark ibr loosing position

[Posterduck]

I have a 2020 spark trixx that has run flawlessly for 430 hours.
Towards the end of the riding season last year here in MN, the ibr started to act up. It is like it was slipping or loosing its position. For example, I would have it trimmed all the way up, and the nozzle would get pushed straight again (not touching buttons and display still showing the position as all the way up). By either clicking the vts button up or down, taping the brake lever and then foward again, or even if enough time passed, it would return to its correct position.
I thought this was the IBR module, so I replaced it this winter. Just put it in the water to test and it is having the exact same issue with the new module.
Any clue what this might be? Such a strange issue.

I recreated the issue on the lift by shaking the gate by hand. You can see at the very end of the video it goes up by itself to where it should be.

Take a look at your IBR fuses. If you don’t have buds, bring it someplace that does. May need a calibration.

I will take another look at the fuses, but they looked fine to me. Calibration was already done after I put the new ibr in.

I wondered if you did that already. If I remember correctly IBR has to be linked to ski. Can the gate be actuated properly through buds?

Yep. vin matched, programmed/updated, and calibrated.
Yes, is moves just fine through buds.

It probably sounds like I’m running through the basics, but have you load tested the battery? You may want to post this problem on seadoospark.org. More people there that have experience than me with working on the IBR.

I actually have not load tested the battery, but I have no indication that it isn't a good battery. It had a nice strong start after sitting all winter disconnected.

The IBR can be extremely finicky with voltage. Sometimes when a battery starts to die it does weird stuff. I once had an IBR light pop up and it was a fuse that somehow wiggled its way out a tad. Pushed all the fuses down and problem went away.

I will track down another battery and see if there is any improvement. I am also suspecting the harness might have issues.

Fuses and battery are not the issue.

That’s a bummer! Is there corrosion on any of the connections? Shooting off the hip, hopefully something hits haha
