S2RV Blinking Dash Lights

[ChuckW]

If you own a 2018.5 or later S2RV chassis, and have the blinking dash light issue, get in touch with Jayco Motorized Customer Service. During a tour of the Seneca line today 7/12, I had a discussion with the Jayco rep. I was told that they, with cooperation with Freightliner, have a fix for this problem. It’s a minor modification that basically keeps the electrons from flowing in the wrong direction.

sounds like the issues when the isolation bridge that Jayco installs on the dash radio head unit. This bridge connects to the radio's "ignition on" input - that then connects to the isolation bridge ( a couple of diodes) that then ties into the Freightliner "ignition on" and the Seneca's "refrigerator 12 power" circuit.

The purpose is so that the radio can be ON without having to turn the Freightliner ignition to ACC/On to listen to the radio when camping.

I am surmising that there could be a change / defect in that isolation where the Freightliner bulkhead module is sensing +12v after the ignition is "OFF" which would be considered a fault.
