Battery Isolator - Parasitic Current
Does the typical battery isolator subject the vehicle battery to any parasitic current when they're in the "cut-out" mode (secondary battery disconnected)?

With the ignition off, the isolator keeps all house loads from the starting battery. BUT the starting battery still has its own parasitic loads on it from the engine computer , dash clock etc.
Some put a small charger on the starting battery to maintain it while the RV is parked and isolator is "open", while the house batts are maintained by something else.
