Engine Cylinder Adjustments
This tachometer has been factory calibrated
for 8 cylinder operation. To adjust for 4 and
6 cylinder engines use a small screwdriver
to turn the switch on the back of the
tachometer until the arrow is pointing to the
desired cylinder number.
NOTE: If your tachometer does not function correctly when connecting the green wire to an aftermarket ignition box, such as MSD, etc., it may become necessary to use
an aftermarket tachometer adapter such as MSD’s 8910 or 8920. Contact MSD for further details on their adapters.
Mounting
The mounting base design offers a variety
of mounting options for best visibility.
• The base can be mounted in forward or
backward position as shown.
• The base can be attached in two different
ways: use the screws provided or use the
self-adhesive mounting pad. (For
adhesive mounting, remove the protective
paper and firmly press in desired location.)
IMPORTANT
The pointer on your
tachometer will not always
rest at zero when the
engine is off. This is normal.
When the engine is started,
the pointer will register the
correct RPM.
Wiring
Connect wires as shown. The wiring diagram
shows installation on vehicles with original
equipment ignitions. If your car is equipped with
a specialty aftermarket ignition, please refer to
the ignition manufacture for the proper hookup
of your tachometer.
Troubleshooting
If your tachometer does not function
properly after hookup, please check the
following:
• If RPM reading seems incorrect, check
cylinder selector switch for proper position.
• If there is no RPM reading, check RED
wire (12V), GREEN wire (tach trigger), and
BLACK wire (ground) for good connection.
• If tachometer reads erratically, check
ignition points for point bounce or for
problems with spark plug wires.
• If problem persists contact Auto Meter’s
service department for assistance.
CAUTION!
As a safety precaution the Red wire of this product should be
fused before connecting it to the positive (+) side of the 12V DC
battery. We recommend using a 4 Amp, 3AG fast-acting type
cartridge fuse (Littlefuse® # 312 004 or an equivalent) inline with
the Red wire of our product.
