Have any conversion folks out their had this happen to them. I've never had this happen till just yesterday.
Any ideas other then disconnect switch being bad?
If you have a bi-directional relay and the voltage was high enough to activate it, the engine can be cranked from the house battery. This is the same relay controlled by the boost switch.
Or, the starting circuit automatically combines house and chassis battery while cranking.
I have a vast knowledge about PV solar, batteries and inverters. I'll try to provide the best answer if I know it and hopefully correct some "Campfire" talk.
