1. Select a location that Is protected from excessive heat, moisture or vibration near either the Voltage Regulator or the back of the Tachometer.
2, Connect a wire between your alternator's Stator/AC output terminal and Regulator's “Stator In" terminal (see Alternator and Regulator manuals for terminal location on your Alternator and Regulator).
3, Connect a wire between your Regulator's "Tach Output” terminal and the "Tach In' terminal on the Signal Stabilizer.
4. Connect a wire between the “Switched Power In" terminal on the Signal Stabilizer and a power source providing positive 12V DC controlled by the keyswitch’s “ON" position. (Hint) This can be the same source as the Voltage Regulator’s Ignition circuit wire (possibly a Brown wire).
5. Connect a wire between the “Tach Out1terminal on the Signal Stabilizer and the signal (sense) input on the Tachometer.
6. Connect a wire between the “Ground" terminal on the Signal Stabilizer and a clean system ground.
. With water to the engine, start the engine and record the actual engine RPM using a Laser Tachometer or other suitable measurement device.
8. Carefully adjust the potentiometer at the center of the Signal Stabilizer’s circuit board until the Tachometer’s display matches the reading shown on the Laser or other suitable measurement device.
9. Increase and decrease the engine RPM while monitoring the Tachometer and Laser Tachometer or other suitable measurement device to ensure that the actual engine RPM and the displayed RPM are in sync.
