Complete, automatic control of
multiple battery systems
Guest battery isolators allow you to connect your
engine alternator to both batteries or banks of batteries
for independent battery charging. They'll also prevent a
higher charged battery from discharging into another,
lower charged battery, by keeping both batteries
electrically isolated from one another.
These solid-state devices act as electronic valves that
keep your charging system operating safely. When your
engine(s) is running, the batteries are charged
automatically. When used with a Guest non-field
disconnect battery switch, you have complete control
over battery selection for power use, plus alternator
protection provided by the isolator. Models are
available for systems with 10-120 amp alternators.
Selecting the Right Isolator for Your System
The first step in selecting the correct isolator is determining
whether your regulator has isolation diodes. With batteries
connected, ignition (key) "off" and battery switch (if you have
one) "on", measure the voltage between the reg/aux/61 terminal
and the engine block with a meter set on 20 volt scale. If the
voltage reading is anything other than zero (0), there are no
isolation diodes. If this is the case, be sure to order the required
kit, #U-3059. The chart below lists the appropriate isolator for
specific applications and alternator outputs. For outboard
alternators other than OMC, order Model #2401A.
