-The HVD mentioned here is actually LVD/HVD.  You can use it to make the isolator a [[electrical:12v:alternator#voltage-sensing_relays|VSR]], turning on at 13.2v (engine running) and turning off at 13.8v (just under alternator voltage). If you wanted to [[electrical:12v:self-jumpstarting|self-jumpstart]] set the connect voltage much lower so the two are connected anytime the key is one.  Or wire a separate momentary ON to energize the isolator.
