Boondocking - power transfer switch (DC to AC ) quit working

my Onan 5500 has a remote start inside and another start switch inside the generator cover in front compartment. Mine did what you're describing during a power outage. tried to restart inside, generator ran but no power. Went outside to switch held in off position for 20 seconds then restarted from that switch, problem solved. generator worked ok after. This may save you
