Here we go again, that old lie. Don't believe every slick sales spiel
you see, even on the web. That is a bunch of BS used to hide the truth
by someone who sells the isolators. The SurePower 1315 Separator  IS a
relay/solenoid!  Is Smith saying that SurePower sells crap? And with the
same breath trying to sell older largely obsolete SurePower Isolator
products?

The SurePower 1315 is a  REQUIRED addon by many fleet vehicle contracts
as the best way to add additional batteries without modifying the base
vehicle charging wiring.
