best guess without more info
is you run the house batteries really low, take off down the highway and the alternator amps into the house batteries is too much for the contacts
these bi-directional are most often used in situations where the RV will be parked in place with shore power, and the bi-direct keeps the chassis battery charged by siphoning power from the house charging converter over to the chassis battery, so it doesn't go dead because of no alternator charging
in reality the Bi-Directional Isolator controls the Relay that connects and disconnects the two battery packs when either has a charging source and there is a 1.3 volt difference.
This one will not connect the house battery to the Chassis battery when the engine alternator is running at 14.3 Volts, and the coach battery is down to 11.0. But the system works normal in all other respects.
