Electric tongue jack question....
We have a Barker 3000 electric tongue jack on our 03 Sunny. I'm thinking it's about five or six years old.
Currently it only works pushing the trailer upward, it will not go down. I've checked the continuity of the switch, it seems to respond correctly. I've tried to bypass the switch, by touching the 12v. incoming power to the lines to the motor with no results at all.
The motor is not shorted to ground as far as I can tell.
All connections are free of corrosion.
