Electric trailer jack
Will my electric trailer jack work if the battery is dead and my truck is connected via 7 prong connector.

Too much voltage drop. I agree with Trackrig.Trackrig wrote:
Most likely not due to distance and too small of wire from the truck battery. If nothing else turn the truck around and hook up a set of jumper cables to the TT batteries.

My TT with electric tongue jack used 10 gauge wire about 4 feet long with a 30 amp fuse. The trucks charge wire is too skinny and long. Also my Ram truck had a fuse on the charging wire...10 or 15 amps I think.
