Additional Regulator Features
Small Engine Mode
In situations where additional power is needed for propulsion, the ARS-5 provides the option to manually
reduce regulator field output by approximately one half. This option, called Small Engine Mode, can be
accessed by creating a direct pathway between the positive and negative Alternator Temperature Sensor
terminals. This can be done by splicing into the positive and negative wires of the Alternator Temperature
Sensor cable (MC-TS-A) with a switched wire. With the switch in the OFF position, the Alternator #1
Temperature Sensor will work normally. With the switch in the ON position, the regulator will reduce field
output by approximately 50%.
To enable the Small Engine Mode:
1.
If the Alternator Temperature Sensor cable is being used, replace the female terminal connectors on the
cable with Multi-Stack Connectors (Ancor Part # 230612).
2.
Install a standard ON/OFF switch in a location that’s easily reached from the helm.
3.
Run wires from the switch back to the positive and negative terminals of the Alternator Temperature Sensor terminals.
4.
Add appropriate connectors to the switched wires and connect to the positive and negative terminal connections.
Dash Lamp
The ARS-5 provides a Dash Lamp circuit that’s capable of providing a signal to a user supplied and installed audible or
visual alert if the following issues were to occur while the regulator is in operation;
•
Low Battery Voltage <12.7V
•
High Battery Voltage >15.5V
•
High Alternator Temperature >226˚F/ 108˚C (Requires installation of MC-TS-A sensor.) Temperature adjustable.
•
High Battery Temperature >125˚F/52˚C (Requires installation of MC-TS-B sensor cable.)
•
Alternator Failure (No voltage on stator).
