Mine came with 40 amp fuse from factory
On Thursday, was just heading out for a long weekend getaway. Stopped to top up with fuel and noticed my tailgate had come down (not shut properly I guess) right onto the electric tongue jack. This in turn, held the switch on, but, because of the size of the fuse, proceeded to burn out the jack motor before the fuse finally blew. Wires melted, really strong burning odor, etc. Luckily, was able to pick up a manual jack and therefore not ruin out weekend.
Why would the manufacturer put in a 40 amp fuse in a 30 amp trailer?
