B.S. or Not - What Machine Could Diagnose a 1969 Mustang
I talked to a mechanic today about some trouble my 1969 Mustang Coupe is having - specifically, it won't start. He said that he could charge $20 to tow it and $40 to hook it up to a machine to see what was wrong with it. Was he B.S.-ing me? How can he hook it up to a machine if there is no computer in the car. Is that possible? What machine is he talking about?
we used them constantly for patterns.
they were a _very_ good indication for compression problems as well. measure amps used during crank on each cylinder gives you a damn good idea
