What's wrong?
The chassis battery on the 2017 Thor Motor Coach Tuscany, Tuscany Zte, and Venetian supplies 12-volt power for starting and for key chassis electrical systems. The isolator relay cable is the heavy electrical cable tied into that battery circuit. Its job is to route power through the relay correctly, so the chassis battery and coach battery systems stay separated while still charging and supplying the systems they are meant to support.
On affected motorhomes, that isolator relay cable was installed incorrectly during assembly. Because the cable is in the chassis battery circuit, a bad installation can interrupt power rather than carrying it cleanly through the relay. Thor Motor Coach duplicated the power-loss condition during engineering checks and updated production so the cable would be installed correctly.
There is no warning sign before failure. The motorhome can lose power suddenly and unexpectedly, so an owner would not have a dashboard light, noise, or gradual symptom to rely on before the electrical failure occurs.
