Installation By Wire
Install BLACK (#1) Ground Wire
The BLACK Ground Wire (#1 in diagram at right) is included in the four-wire Ford-style plug on the wiring harness and is
factory installed on regulator packages designated with “H” at the end of the model number. The other end of the Ground
Wire is fitted with a ring terminal connector. In most applications, this wire can be
connected directly to the alternator’s ground terminal post. Both alternators and
regulators must be connected to system ground.
Install RED (#2) Power Wire
The RED Power Wire (#2 in diagram at right) is included in the four-wire Ford-
style plug and is factory installed on regulator packages designated with “H” at
the end of the model number. The other end of the Power Wire is fitted with a ring
terminal connector. In most applications, this wire can be connected directly to
the alternator’s positive output post. When a diode-type battery isolator is used,
the power wire must be connected to the battery side of the battery isolator.
Power Wire is equipped with 10-amp ATC type fuse. The Power Wire must be
fused to ensure against damage to the voltage regulator.
Install BROWn (#3) Ignition Wire
The BROWN Ignition Wire (#3 in diagram at right) provides the ON/OFF voltage
for the regulator. This wire is included in the Ford-style plug at the regulator end
of the wiring harness. The other end of the wire is fitted with a butt connector.
Typically, the ignition wire is connected to the ON side of the ignition switch. This
may be at the actual switch, or to the wire in the existing engine wiring loom that
delivers switched voltage from the ignition switch. In some cases, an oil pressure switch may be used to activate the regu-
lator. In either case, the regulator’s ignition wire must see zero volts when the engine ignition is switched off.
Install BLUE (#4) Field Wire
The BLUE Field Wire (#1 in diagram at right) provides regulated current to control alternator output. The wire is included
in the wiring harness Ford-style plug and is pre-connected at the regulator. At the other end of the wire, you’ll find either
a plug or a ring terminal, depending on the alternator’s field terminal connection. Attach the field wire to the alternator’s
field terminal.
Install Battery Temperature Sensor (#5 Positive, #6 negative)
The optional Battery Temperature Sensor (MC-TS-B) allows your ARS-5 voltage regulator to monitor your battery bank
for changes in battery temperature, and adjust charging voltages to suit. The MC-TS-B sensor includes a 20-foot cable, a
sensing attachment lug and positive and negative regulator plug-in connectors. To install the MC-TS-B:
Connect sensor lug to the negative post closest to the center of the battery bank. Extend sensor cable to regulator.

Connect the positive and negative female connectors to the Battery Temperature Sensor on the regulator (#5 is posi-

tive. #6 is negative). It is essential that the terminals match the polarity of the regulator connection pins (red wire to
positive terminal and black wire to negative terminal connectors).
Install WHITE Stator-In (#7) And Tach-Out (#8)
When an electric tachometer is used, the alternator’s stator output will
provide the electrical pulse needed to drive the tachometer. The ARS-5
has been designed to provide regulated tach output when the WHITE sta-
tor wire is connected to the regulator’s Stator In (#7 in diagram) terminal
and the outfeed wire to the electric tachometer is connected to the Tach
Out terminal (#8 in diagram). Stator output can also be used to detect
alternator failure. See Basic Programming information for details.
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. See
alternator manual for specifics. See your tachometer manual for adjust-
ment instructions.
