Electric A-Frame Trailer Jack Does Not Run and Light Does Not Work

Question:

It work fine yesterday. Today its completely nonfunctioning, no light, no motor, nothing. We had to jack up the side today today to change a tire. Would this affect it?

If the electric jack's fuse is blown that would explain everything. Some jacks have an external fuse like # LC285318. Others will have it or a circuit breaker inside of the unit to where you would have to remove the covers to access it.

It could also be a bad ground or a drained battery. If there isn't a separate ground wire then the jack grounds through where it is mounted. That surface will need to be clean and free of corrosion for a good ground connection. And if the battery that drives the motor is dead then the jack won't work. You could have the battery tested at a local auto parts store to determine if that is the problem.
