Good one Doc, not a lot of folks know how to do a voltage drop test on a component system. This is the most accurate way to diagnois a faulty circuit, relay, component or ground.
I had a 67 Taurus that developed a hesitation problem when accelerating rapidly in traffic. After some trouble shooting I found the alternator voltage would drop 2-3 volts when engine speed was accelerated. Replaced the alternator and the hesitation problem went away.Good one Doc, not a lot of folks know how to do a voltage drop test on a component system.
