2003 Ford F250 No Start Do to VD Voltage Drop

A 2003 Ford F250 pickup truck was towed in as a NO START. At AutoClinic we "Test No Guess". We performed electrical testing and found a Voltage Drop that was preventing the engine for starting. We tested the circuit and located the problem using basic and high tech equipment. Using our labscope we were able to show our customer the visual of the voltage drop.
