SEMI-TACHLESS MODE
This new feature provides an easy method of starting the vehicle without locating the exact tach wire required. It
uses a timed crank output combined with the tach wire as a crude pulse monitor. This combination prevents the
starter from engaging into an already running engine and provides a reliable method of detecting when restart is
required. There are 4 different crank times available for use.
HOW TO USE THIS FEATURE:
1) Program the "Engine Sense" for "Timed Crank".
2) Next program the "Crank Time" to the appropriate time required for engine starting. This is determined by
starting the engine with the key and estimating the amount of time it takes before the engine begins to run. We
recommend starting with the minimum time, which is already preset for 0.75 sec.
3) Connect the RED/WHITE tach wire to ANY negative coil trigger wire, OR see Tach Amplifier instructions on
previous page. The system is now configured for Semi-Tachless operation.
WARNING: This method of starting the vehicle is not as reliable as using the TRUE TACH LEARNING.
This method should be used only in the event that a tach wire cannot be located using the normal tach
programming and tach amplifier. When using this method, there may be certain operating anomalies
requiring seasonal adjustments. These are, but not limited to:
•
Starter may under crank in extreme cold weather. Vehicle may start on 2nd or 3rd attempt, or will
require programming.
•
In warm weather starter may tend to over crank, and may require reprogramming from the winter
setting.
VACUUM SWITCH
This is to be used only in the event that a tach sense wire cannot be found. A simple Vacuum controlled switch,
installed on the intake side of the engine, is used to signal the starter module that the engine is running. When the
engine is NOT running, the switch rests at ground. When the engine starts, the engine vacuum opens the switch
causing the ground to go away. This tells the starter module the engine is running. Connect Vacuum Switch per the
instructions included with switch. Vacuum mode is programmable. Make certain tach amplifier is off.
3 PIN GREEN ACCESSORY PLUG
PIN 1: EMPTY, PIN 3: EMPTY
PIN 2: ORANGE: OEM RE-ARM WIRE
This wire provides a negative output in sequence with the lock pulse of the system. This wire is to be connected to
the door pin switch wire to simulate a door being open when the system is locking in order to ARM some types of
OEM Factory Security Systems. This wire can be connected directly to a Negative OEM arming wire if one is
available.
