The SurePower 1315 is NOT an isolator, it is a smart separator. There is
no voltage drop with it. The older diode type isolators do have a
voltage drop but not this separator. The 1315 is the best way to go for
a Vanagon, IMHO, since it requires no modification to the alternator or
to the base vehicle wiring.

The 1315 product IS a smart relay.
