What's wrong?

The transfer switch in these 2007-2011 Jayco Greyhawk, Seneca, Eagle, Recon, and Designer vehicles manages electrical power when the coach changes between power sources. Inside that switch, the buss bar is the metal connection point that carries and distributes current through the switch. It has to stay tight and properly connected so power moves through the system without excess resistance.

On affected Jayco vehicles, the Iota-brand transfer switch has an improper electrical connection at the buss bar. That bad connection changes the way current passes through the switch, which puts stress on the electrical system at a point that handles coach power. The issue is in the connection inside the transfer switch, not in a normal owner setting or campsite power choice.

There is no warning sign before failure. An owner should not count on a dashboard light, visible damage, or a change in how the vehicle drives to identify this defect.
