I would say to call your local Lance dealer. If they say bring it in, and our repairmen can fix it for a fee, thank them kindly, and tell them they have not helped at all. Even using a few gallons of gas to take it someplace is not all that helpful.
Paying them to tell you the wire ends at the fuse box, and the factory did not install the fuse would add insult to injury.
If the dealer is no help, call the factory and let them know what dealership was of no help. Be sure to get the name of the not so helpful person (before asking any questions).
Fred.
