Like you, I tested all the fuses inside the trailer and they are all fine. Next, I'll open the jack and look for its own fuse.
Any guidance will be much appreciated!
Its hard to tell from the picture but that may be an automatic resetting fuse or it could be the manual reset type, look it over for a reset button., that may used in place of the usual 30 amp ATC fuse, is it located on the trailer side of the battery. Most jacks will have a 30 amp slow blow inline fuse running from the jack motor to the battery, you will have to locate it and give a visual inspection.
