Old sears analyzer that works well. For checking Points, Dwell, Battery, Charging system. Great for anyone with a classic car in use or for a vintage tool collector. The original box is a little dirty from being on a shelf for many years. Works fine. Comes with the original Instructions. See the photos, buy it for use or for anyone with a classic car. I also have an old sears timing light for sale on here. They both came from a retired military guy that took care of his own vehicles up until the 80's.
