A member with a 2011 Chevy Roadtrek 210 Versatile reported that Starlink drained the new AGM house batteries and also left the van battery dead, leading them to suspect the battery isolator or separator. Members said this model likely uses a Sure Power-style coil relay separator mounted high on the firewall toward the passenger side, and that the round coil section can get very hot when activated, which is not automatically proof of failure.
Members suggested disconnecting both battery banks before testing or replacing it, then checking the separator posts for continuity with a multimeter. Several members favored upgrading to electronic or magnetic-latching Blue Sea charge relays because they draw less power and avoid the heat of the original coil type, while one member noted the original Sure Power 1315 may have had overheating concerns. A temporary jumper cable across the separator terminals was suggested only while the engine is running to charge the house batteries, with the caution to remove it when shutting down so the starting and coach batteries are not left tied together; the issue remained unresolved as the member planned to have an RV tech handle the separator along with generator and other repairs.
