    INTRODUCTION The Model 091-139-2-12 AUTO ISOLATOR I system is a lossless isolator replacement for the conventional diode isolator. Designed to be installed in a vehicle with one or more Main batteries that must be isolated from one or more auxiliary batteries. The system consists of a voltage detector and controller Model 091-139-CONT-12 and a separate 200-ampere rated solenoid, Model 091-139-SOL-12HO for switching the batteries.
