Install Alternator Temperature Sensor (#9 Positive, #10 Negative)
The optional Alternator Temperature Sensor (MC-TS-A) allows your ARS-5 voltage regulator
to monitor your alternator for temperatures in excess of safe operating levels. The MC-TS-A
sensor includes a 54” cable, a
sensing attachment lug and positive and negative regulator plug-in connectors.
To install the MC-TS-A:
1.
Connect the sensor lug to the terminal provided (6-Series) or one of the four bolts that
hold the alternator’s front and rear cases together. Extend sensor cable to the regulator.
The cable can be included within the regulator’s wiring harness, or can be run alongside
the harness and attached with cable ties.
2.
Connect the positive and negative female connectors to the Alternator Temp. Sense
terminals on the regulator (#9 is positive. #10 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).
Install Dash Lamp (#11)
The Dash Lamp (#11) terminal provides the ability to activate a visual or audible indicator when the regulator monitors
the following conditions: Low system voltage, high system voltage, high alternator temperature, high battery temperature
(temperature conditions are only indicated when appropriate temperature sensors are connected) and no voltage on stator,
indicating that the alternator has failed. When a described condition is detected, the regulator sends the Dash Lamp terminal
from neutral to ground. To utilize the Dash Lamp function:
1.
Connect a small LED or incandescent lamp, or an audible (piezo) alert (maximum current flow is 500 mA) to a positive
voltage source.
2.
Connect the negative terminal on the lamp or audible alert to the Dash Lamp terminal on the regulator.
3.
When connected, the lamp should flash at regulator start-up to indicate active status.
Magnetic Reed Switch
Looking much like a small thermometer atop the regulator’s
circuit board, the magnetic reed switch provides a durable,
sealed interface that enables the user to set basic and
advanced regulator programming features. Included with
the regulator is a small screwdriver that doubles as the regulator’s programming tool. A small magnet embedded in the tip of the
screwdriver’s handle allows the user to activate the magnetic reed switch. By holding the magnet to the RED dot located at the
end of the reed switch, the user can scroll through the regulator’s various program modes and individual program selections.
Initial Pre-Flight Test And Start-Up
When the regulator is properly mounted and the regulator wiring is installed, the ARS-5 is ready for pre-flight testing. Before
turning on the engine, it is advisable to check voltages at the following terminal connections to ensure that the wiring is correct.
Test #1 verifies proper voltage values with the regulator turned off. Test #2 verifies the expected voltages with the regulator
turned on.
Note: If the regulator’s BROWN ignition wire is receiving it’s switched source of voltage from an oil pressure switch, it may be
necessary to start the engine before applying test #2. If the engine must be run to accomplish test #2, be sure that alternator is
properly cabled on both positive and negative sides to the battery being charged. Failure to do so could result in damage to the
regulator and alternator.
Using your hand-held multi-meter, test the following wiring terminals for voltage:
TEST #1: Engine/Ignition Off
•
Primary RED Power Wire (Terminal #2) >12V
•
BROWN Ignition Wire (Terminal #3) 0V
•
Primary BLUE Field Wire (Terminal #4) 0V
CAUTION: Reversing the polarity of the terminal connections on any of the alternator or battery
temperature sensors can result in invalid sensing and potential damage to alternators, regulator and/or
batteries.
