Our 2004 National Tropi-cal has been idle for the past six months but plugged into 50 amp power with inverter/charger continuously on line.(as we have done last 15 years). Began traveling 4 days ago a...

1. Your dash Boost switch is energized by the COACH batteries. So, if low and not enough to engage the boost solenoid, that is your problem
2. From your description of the storage time, Have you checked the Coach battery water? I suspect they boiled from long term storage
3. HOW old are the Coach batteries
4. Cannot remember about the 458 Freedom, but some Inverter/Chargers will not engage the Charger function when 120 present if the battery voltage is below 10 to 11 volts. You must either use an external source to get a temporary line voltage to 12 volts for 5 to 10 minutes and then the Inverter/Charger will come on line to charge
5. National used a Board assbly, usually in a Storage compartment by the entry door, that had the Bi directional and Boost relay's mounted in that panel. With various fuses. 14 years and one of those relay's failing would not be unusual. This assbly controls BOTH the Chassis charging the coach and the Boost going to the chassis battery.
6 The boost is designed for latching the Coach to the chassis to start the chassis engine, not the other way. That is why if the coach batteries are dead/low, the system does not function. Doug
