"when you forget to disconnect from the engine battery"
A dash switch is different? My recommendation is to suffer testing all those "BIRD" points with a meter (while holding a troubleshooting guide) to the maze of connections to find the problem.
A dash switch typically is different. It's usually a momentary switch that is pressed to jump the coach batteries to the engine battery in the event that the engine battery is dead. Once started you release the switch.
The diagram I posted is overly complicated because they included two battery disconnect solenoids.
