Older Sears unit. Model 161.2161. Engine Analyzer for 4, 6, and 8 cyl. Has red, black, and green hook up leads. Need hook up info to test dwell, points, volts, amps, and engine RPM. Any help appreciated.
Not the exact model, but should give you enough info to get yourself in trouble... http://www.manualslib.com/manual/496674/Craftsman-161-216300.html
