Auto Meter PRO-CYCLE 19304 Installation Instructions

2650-600X-10 Rev. B
Important Notes
1. This tachometer has an air core meter. The tach pointer may not always rest at zero. This is normal. When engine is started, pointer will
position on the correct RPM.
2. This tachometer is not waterproof. We strongly recommend that you take precautions to protect your tach during vehicle washings.
3 An under-charged battery may cause incorrect tach operation. Also avoid connecting tach in series with ballast resistor.
4. When charging battery, make sure the tachometer is disconnected from the battery.
5. Use only supplied or recommended mounting options for your tachometer. Others may void your warranty.
6. Solid core ignition wires may cause tachometer interference.
7. Isolate tachometer wires from ignition and ignition wires.
8. Ignition manufacturers recommend that the ignition and coil be matched according to criteria which they establish (often the ignition and coil are
products of the same company). Mismatching coil and ignition types may cause erratic tachometer operation.
9. If you are using a points ignition or your ignition module does not have a tachometer connection, connect the green tach wires to the negative
side of the coil or coils. If you are using a two-coil ignition connect one green wire to the negative side of each coil.
Calibration
(Models 19304, 19305, 19324, 19325)
Before wiring your tachometer determine the required pulse per revolution for your application. This tachometer comes from the factory setup to
operate in a 1 pulse per revolution application. If your application is 2 pulse per revolution, follow the instructions below.
If used on a 2 pulse per revolution system, remove the screw at the rear of the cup.
This requires a 3/32" Allen Wrench. Carefully slide the cup back along the wires
to expose the inner case. Remove the snap in light socket assembly to access the
cylinder select switches. The switches are located to the left of the light hole. Use a
small screwdriver or an unwound paper clip to change the switch settings.
