TACHOMETER CONNECTIONS (Cont) 3
Connection Instructions for OPTION #3 - Inductive Pick-Up
on Spark Plug Wire
1. Connect the Inductive Pick-Up to a spark plug wire as follows (see Figure 3):
A. Use an existing firewall grommet, or drill a 3/8-inch (9,5 mm) hole
through firewall. Install a grommet in hole and route the Inductive Pick-
Up 4-pin female connector from the engine compartment side through
grommet and to the tachometer gauge.
NOTE: The Inductive Pick-Up lead wire is a special shielded wire. DO
NOT cut the wire.
B. Plug the 4-pin Inductive Pick-Up connector into the 4-pin connector #1
on back of tachometer.
C. Remove the screw and nut from the Inductive Pick-Up Clamp.
D. Find a spark plug wire, and clamp the Inductive Pick-Up around the
wire. Make sure that the arrow stamped on the Inductive Pick-Up clamp
points toward the spark plug.
E. Re-install the screw and nut to secure the inductive pick up clamp on to
the spark plug wire.
2. Proceed to the "CYLINDER SETTING INSTRUCTIONS" section to adjust
the tachometer to the proper Cylinder/RPM setting for the "Inductive Pick- Up
on Spark Plug Wire” option.
Shift Light Operation and Setting
The shift light can be used to provide a visu-
al indication of engine "Red Line" (maximum
safe engine speed) or optimum gear shifting
engine speed (to improve vehicle perform-
ance when shifting gears). See Figure 5.
Setting Shift RPM
1. With the ignition key in the "ON" posi-
tion and the engine "OFF" (not run-
ning), press and hold down the shift
light set button. After about 4~5 seconds, the needle will start moving up the
display. Continue holding the shift button down and proceed to step 2.
2. When the tachometer’s needle indicates the desired "shift RPM speed" on
the display, release the shift light set button. The "shift RPM " is now set in
the tachometer's memory, and the shift light will illuminate every time the
needle reaches or exceeds the set "shift RPM ".
3. After the "shift RPM " is set, press and release the shift light set button to
return to the normal tachometer operating mode.
4. To check the shift light RPM setting, press and release the shift light set but-
ton. Press and release again to return to normal tachometer operation. If
the "shift RPM setting" needs to be changed, repeat steps 1~3.
SHIFT LIGHT/RPM RECALL OPERATION (For Shift Light/RPM Recall Tachometers Only) 5
Peak RPM Recall Function
This function saves the highest (peak) RPM that was achieved during a trip in
the tachometer's memory and gives the operator the ability to recall this infor-
mation at any time.
To view the peak RPM value stored in recall memory, press and release the
RPM recall button. Press and release again to return to normal operation.
NOTE: The Peak (highest) RPM achieved during a trip will remain in the
tachometer’s memory until overwritten by a higher RPM valu, or until the mem-
ory is cleared by the operator.
Clearing Peak RPM from Tachometer's Memory
1. Press and release the RPM recall button to place the tachometer in RPM
recall mode. The needle should rise and remain at whatever value is in
Recall Memory.
2. While tachometer is in RPM Recall mode, press and hold the RPM Recall
button. Within 3 ~ 4 seconds, the tachometer’s needle will begin to move
down. Wait until the needle reaches zero, then release the RPM Recall but-
ton. The RPM Recall memory is now cleared, and the tachometer will begin
saving the highest (peak) RPM reached during the next trip.

If the tachometer does not function, or functions erratically, perform the following:
■ Ensure that the ignition system is in good working order in accordance with
the vehicle manufacturer’s specifications. If the ignition system is in good
working order but you still experience erratic readings, the tachometer may
be picking up Electromagnetic Interference (EMI). Try re-routing the Inductive
Pick-Up lead wire or the GREEN tachometer signal wire (whichever is appli-
cable) away from all other spark plug wires, ignition coils and the alternator.
TROUBLESHOOTING 6
■ If the Inductive Pick-Up option is being used, reverse the direction of the
Inductive Pick-Up clamp on the spark plug wire so the arrow points away
from the spark plug. If this is unsuccessful, try moving the Inductive Pick-
Up clamp to a different location on the spark plug wire, or to a different
spark plug wire.

CYLINDER SETTING INSTRUCTIONS 4
The tachometer's CYL setting must be adjusted to match the tachometer's
internal settings to the RPM signal received from the vehicle's ignition system.
Adjust the settings as follows:
1. Make sure the tachometer power and
ground wires are connected to the vehi-
cle, and the 3-pin connector is plugged
into the #2 connector on back of the
tachometer.
2. Remove power from the tachometer
(turn ignition switch off). Press and hold
the CYL button (small RED button on
rear of tachometer, see Figure 4), then
apply power to the tachometer (turn igni-
tion switch on).
3. Press and release the CYL button as many times as required until the
tachometer's needle points to the correct RPM for the signal hookup option
used.
■ Use the settings in Table 1 if "OPTION #1- Direct Hook Up with GREEN
Wire" or "OPTION #2 -Inductive Pick-Up on Coil Wire” is being used.

4. When the correct cylinder setting is obtained, turn the ignition off. The cylin-
der setting is now saved in the tachometer's memory, and will remain until
changed. To change the setting, repeat steps A through D.
5. Proceed to "Tachometer Operational Checkout" to finish installation.
Tachometer Operational Checkout
1. Turn on ignition. DO NOT START ENGINE. Tachometer pointer should rotate
to "0" when ignition is turned on.
NOTE: This tachometer utilizes an "Air Core Movement". With this type of
movement, the needle will remain (point) at whatever position it was in (not
necessarily zero) at the time the power to the tachometer was removed.
This behavior is normal for this type of needle movement. The needle
should return to zero when power is reapplied to the tachometer.
2. Start and run engine. Rev engine several times and verify tachometer indica-
tion changes as RPM increases and decreases. If tachometer fails to oper-
ate, or operates erratically, consult the Troubleshooting section for trou-
bleshooting details.
