Hi All. Got a 07RXP. I have a strange problem with my ski. VTS and speedo does not work when I run the ski. VTS works fine when I switch on but as soon as the motor runs vts stop working. Same problem with the speedo. Works fine when I turn paddle wheel by hand but as soon as the motor runs speedo reeds 0.

There was however a modification done to the dess post. A separate kill switch was installed because ski does not shut down when dess key is pulled, therefore the kill switch mod was done.

Any help would be appreciated.
