What's wrong?
The Iota ITS-50R transfer switch in these 2009-2011 Four Winds Mandalay, Serrano, Hurricane, Windsport, and Magellan motorhomes is part of the electrical system that routes generator power into the coach. When it works correctly, the switch carries that power through internal metal bars and connections so lights, appliances, and other coach circuits receive power safely.
On affected motorhomes, the connections at the buss bar inside the switch are not adequate. A buss bar is a metal strip that carries electrical current from one point to another. When the coach is under elevated electrical load and the surrounding temperature is high, those weak connections create extra heat. That heat can make the transfer switch fail.
Owners can notice an electrical odor before the switch fails. Treat that smell as a warning sign from the electrical system, especially when the generator is powering the motorhome.
