ACTRON Automotive Analyzer-Tach-Dwell-Voltmeter No 615 USA Made

Made in USA ACTRON Analyzer Tach/Dwell/Voltmeter for 12 Volt Electronic or Conventional Ignition Systems Model No 615
This analyzer has been hardly used and is in very good condition. The box shows evidence of multiple moves but the meter spiffy-clean. I have owned this ~35 years and just once used it. I just tested it and it works flawlessly. This analyzer tests 12 volt conventional & electronic ignition systems using vehicles battery 4, 6 or 8 cylinders domestic or imported. It is housed in a red polycarbonate housing with a 6" meter. No batteries are required, it is powered from the car's 12v system.
I bought this May 7, 1988 in Tucson and only used it once. Included is the owner's/instruction manual which will open up all the various uses which can be performed with this beauty
