Install Battery #1 Temperature Sensor
The optional Battery Temperature Sensor (MC-TS-B) allows your Max Charge MC-618 voltage regulator to monitor your battery
bank for changes in battery temperature, adjust charging voltages to compensate for battery temperature, and respond to a
battery over-or-under-temperature condition by discontinuing charging. The MC-TS-B sensor includes a 20’ cable, a sensing
attachment lug and positive and negative regulator plug-in connectors. To install the MC-TS-B:
1.
Connect the sensor lug to the battery negative post closest to the center of the battery bank. Extend sensor cable to the
regulator.
2.
Connect the temperature sensor to the Bat. #1 Temp. terminals on the regulator. It is essential that the terminals are
connected to the correct pin.
Connect the RED wire to the positive terminal (#8) and the BLACK wire to the negative
terminal (#7).
NOTE:
Do not crush, crimp or bend the portion of the sensing lug covered by heat shrink
tubing. Doing so can destroy the sensor and is not covered by warranty.
Install WHITE Stator-In And Tach-Out Wires
When an electric tachometer is used, the alternator’s stator output will provide the
electrical pulse needed to drive the tachometer. The MC-618 has been designed
to provide regulated tach output when the WHITE stator wire is connected to the
regulator’s Stator In (#12) terminal and the out feed wire to the electric tachometer is
connected to the Tach Out terminal (#13) terminal. *Not required for magnetic pick-up
tachs.
Stator output can also be used to detect alternator failure. See Page 10
for details.
When the tachometer is connected via the MC-618, the regulator will ensure that the tachometer will not discontinue supplying
field current when the batteries are fully charged. When connecting the tachometer to the alternator stator output, it will
be necessary to determine the number of poles in the alternator in order to properly adjust your tachometer. Most Balmar
alternators feature 12-pole rotors and stators, though, in some cases, the pole count may be 14 or 16. See alternator manual for
specifics. See your tachometer manual for adjustment instructions.
Install Battery #2 Temperature Sensor
Your Max Charge MC-618 voltage regulator can accommodate a secondary battery temperature sensor. Used in conjunction
with an optional MC-TS- B battery temperature sensor, the regulator can monitor temperature at a secondary battery bank and
respond to a battery over-temperature condition by discontinuing charging.
To install a secondary battery temperature sensor:
1.
Connect the temperature sensor to the secondary battery bank following the directions provided for the primary battery
temperature sensor.
2.
Connect the temperature sensor to the Bat. #2 Temp. terminals on the regulator. It is essential that the terminals are
connected to the correct pin. Connect the RED wire to the positive terminal (#15) and the BLACK wire to the negative
terminal (#14).
Install Aux. 1 Lamp
The Max Charge MC-618 regulator’s Aux. #1 (#16) terminal provides the ability to use a visual indicator when the regulator is
operating under the following conditions: Full field (the alternator is working at full power) and Small Engine Mode (the regulator
is being controlled at 50% field output). When a described condition is detected, the regulator sends the Aux. #1 terminal from
neutral to ground. To utilize the Aux. #1 Lamp function:
1.
Connect a small LED or incandescent lamp (maximum current flow is 500 mA)
to a positive voltage source.
2.
Connect the negative terminal on the lamp to the Aux. #1 terminal on the
regulator.

CAUTION:
Reversing the polarity of the battery or alternator
temperature sensors will damage the sesor and is not
covered by warranty. Ensure that the connections are correct,
and never re-connect with the regulator powered.
