X2 need to know the model and year to really be able to help.
If you have say a Hummingbird, it maybe zero amps. If you have say a Northpoint it could be a couple amps maybe even more, as the leveling system and remote control devices always have power to them.
A simple multimeter with an amp clamp is a good friend to keep in the camper, to help diagnose issues. Don't need anything fancy, but it can diagnose a lot of issues.
