Hello everyone, I've just replaced the trim sender on my 2008 VP SX-A drive and I am finding a similar problem than what was described above: I positioned my drive all the way down, adjusted the sender to a full down (in) position to show up on the gage and fixed the sender in place. When I trim it all the way up, the gage needle goes only to the middle and not all the way up. I am struggling to find any hint on that the problem could be. The trim sender is an original 3 wires VP PN 21484383. Any help would be appreciated. Thanks

I believe you have to remove the sender and set it at 11ohms which is full down then reinstall.

Thank you very much 89retta. This is the procedure I used to install the sender, as you just described: set it at 11ohms and then install. It works perfect on the full down (in) position and the gauge reads it correctly, but when I trim it all the way up, the gauge goes only 1/2 way up, not all the way up...

11ohms to me is just a guideline for installing it after that you move it c-hair by c-hair untill it reads correctly on your gauge that is why there is the slot adjustment every gauge is slightly different from each other having two people makes the job much quicker
