Position 1
Position 2
Position 3
Position 4
Note:
Customers with isolators: Use switch position 2 or 4 only, otherwise battery overcharging may occur.
Customers without isolators: Use switch position 1 and 3 only if vehicle is equipped with
a diode battery isolator module for multiple battery packs.
If in doubt, please contact the vehicle manufacturer for battery information.
1. Before installing, turn regulator over and select
appropriate voltage setpoint for battery type and
charging system configuration (See Table 1 and
Fig. 1).
2. Install regulator as described by the vehicle-level
installation instructions.
3. Plug the regulator-to-alternator harness into the
alternator.

4. If battery sense cconnection is used with the
application, connect as shown in Figure 2.
Battery sensor connector monitors the actual
battery terminal voltage and temperature.
Temperature sensor is 10K
1.256KΩ at 80ºC. If battery sense connection
is not used, the regulator reverts to an internal
voltage and temperature reference.
5. LED will flash RED when voltage is high,
AMBER when voltage is low, GREEN when
voltage is normal. LED will remain steady RED
when OVCO circuit has activated. Alternating
AMBER/RED will flash when the battery sense
harness becomes disconnected. On applications
without the battery sense connection, the LED
will always flash AMBER/RED regardless of the
state of alternator voltage because the battery
sense connection is not used.
