I really don't understand the upgrades that would be needed anywhere to the electrical supply at an RV park. Most all electrical vehicles can be charged using 120v, it just takes a longer time. but if you're RVing than you would have to stay at least...
Sounds like the limit switch to me. When you are holding the 2 blue wires together you are bypassing the limit switch, about a $7.00 part. Usually looks like a small button with 2 blade wire connections, has 2 small screws holding it on.
