Firefly / Won't Communicate with Inverter
I've got a 2018 Tuscany 40RT.
Firefly system worked great for 5 months and 8,000 miles. On recent trip home from factory to Oklahoma, we dropped out inverter power to interior 120V outlets.
After doing 'soft reset' of inverter, we have 120V back at outlets. However, the Firefly does not communicate with inverter. See below.
I checked Magnum RVC Bridge. It is not getting power from the orange communication bus cable. I checked the 2 power leads (per Magnum), and found no voltage on leads 3, 4. Where in the heck do I find the problem?
Called Thor warranty support. They want me to take to a dealer. I hate that idea. I should be able to fix this problem. One idea they mentioned is that the RV-C cables might have a loose wire, or one connector is mis-wired (I doubt this since it worked fine till now). I'm going to check them tonight.
Any ideas from you with experience on these multiplex systems?
