The Ideal Regulator Output Module may be located anywhere convenient to the
alternator that is not subject to salt or fresh water spray. The components in this module
have been coated to resist corrosion but are not immune to, nor warranted against, abuse.
This module has on it the FET (field effect transistor) that actually does the work of
supplying power to the alternator field. While the reliability of this module is very high it
also does all of the real work. The system has been designed with on site repairability in
mind, a spare Output Module or a standby regulator should be considered for long distance
cruising.
The harness that is supplied with this module is a standard alternator harness. It is
keyed so that it cannot be improperly plugged into the module. The colors mentioned below
correspond to the color code of the wiring harness. There is also a 25' 8 conductor phone
cord supplied to interconnect the Monitor Terminal Board and the Ideal Regulator Output
Module. The following discusses each of the wires connected to the Ideal Regulator Output
Module beginning from the left side of the module.
FIELD WIRE, BLUE:
The BLUE FIELD WIRE is connected to the FIELD
TERMINAL on the back of the alternator and supplies field current. The gray insulated
plug connector may be plugged directly into standard small case high output alternators.
(NOTE: The white wire that is stubbed out of the gray plug is for electronic tachometers
and has no function related to alternator regulation.) If the plug will not fit into the alternator
it may be cut off and the blue wire may be terminated with an insulated spade terminal or
other appropriate connection for the alternator field terminal. The RED LED, on the Ideal
Regulator Output Module, labeled CHG indicates field current is flowing.
The RED LED
glows more brightly as the alternator output increases.
Neither the GREEN or the RED LED should be ON when the engine is off!!!
If the RED LED is ON, and the green LED (labeled "ON") is OFF, it is an indication
that the FET is shorted or the field is connected to some other source. DO NOT
OPERATE THE SYSTEM UNTIL THIS IS RESOLVED!
CAUTION:
The gray plug will fit into the typical DELCO internally regulated
alternator but the internal regulator must first be disabled.
DO NOT attempt to use the
Link 2000-R with an internally regulated alternator without modifying it to use
external regulation! See #4 on page 8.
REG ON WIRE, BROWN:
The BROWN REG ON WIRE turns on the regulator. It
should be terminated on the recommended oil pressure switch, or some other switch (i.e.
ignition switch or relay), that is hot (+12V) when the engine is running and off when the
engine is off. If the system has an isolator or separate engine starting battery the BROWN
WIRE should be supplied from a stable 12V source. This wire must not be connected to
the oil pressure sensor for the oil pressure gauge or to the oil pressure switch for the alarm
system. A separate normally open oil pressure switch should be used. When this wire is
energized the GREEN LED labeled ON is lit.
The GREEN LED must be OFF when the engine is off! If the regulator is left
continuously ON it may destroy the Ideal Regulator Output Module, damage the
alternator, discharge the battery, and cause system failure.
