i sure have measured a voltage between house batt pos term and the unconnected ground cable before.
i may be needing a 3rd solenoid, today i felt the iso solenoid and it was warm. it was not latching to allow shore or genset to charge chassis, only house batt was getting 13.++ i tapped solenoid w/ a tack hammer a few times and it must've latched as chassis batt voltage read 13.xx
strange behavior such as needing a quick on/off toggle to reverse polarity and force these BIRD isolator solenoids to unlatch and/or lose 12v between two small terminals after charging was discussed in markopolo's classBforum, so it's not my imagination.
DPDT tames BIRDi would dearly love to get to a simpler setup where house and chassis are totally separate like in many older rigs. this can include the qwikee step/ignition and emergency start wiring as well. i just don't know how to safely disengage all this hardware what my rig has.
