TIC TOCK TACHMETER ONLY TACHOMETERS HAVE ELECTRONIC MOVEMENT. THEY WILL RESET TO “0” ONCE THEY HAVE POWER FROM DISTRIBUTOR OF 12 VOLTS. ALL TACHOMETERS HAVE TWO LEADS, ONE FOR 12 VOLTS, AND THE OTHER IS “S” FOR SIGNAL FROM DISTRIBUTOR. THIS TACH WILL WORK WITH FACTORY GM POINTS OR FACTORY HEI. IT MAY NEED A TACH ADAPTER WHEN USING THIS ON MSD OR AFTER MARKET IGNITION. TACHOMETERS WILL WORK WITH FACTORY GM POINTS OR FACTORY HEI IGNITION. WHEN USING AN AFTERMARKET IGNITION SYSTEM LIKES MSD, ACCEL, PATRONIX, ECT. A LOT OF THESE SYSTEMS GENERATES HIGHER OUTPUT VOLTAGE TO THE TACH LEAD THAN WHAT A FACTORY GM TACH CAN HANDLE. FACTORY GM TACHS CAN OPERATE ON VOLTAGE RANGING FROM 11.2 TO 14.7 MOST AFTERMARKET IGNITION SYSTEMS GENERATE OVER 18 VOLTS. YOU WILL NEED TO BUY FROM THE MANUFACTURE OF YOUR IGNITION SYSTEM AN ADAPTER TO LOWER THE VOLTAGE TO THE GM FACTORY VOLTAGE.
