I was trying to figure out why my 1986 F150 wasn't holding charge and found out it was the battery. I had pulled the alternator and battery off to have them tested. While reinstalling the alternator I touched a hot wire to the frame and now it won't crank. When I turn the key I no longer hear the file pump or anything under the hood turn on. It will turn over but not fire. Any help would be appreciated.

Truck will not crank

In addition to ignition, power and monitoring gauges and lights, today's motor vehicles feature computerized engines, transmissions and braking systems, electronic mapping systems, Bluetooth and Internet connectivity, sensors that detect other vehicles, motorized seats, and digital audio and video systems; several manufacturers are producing electric and hybrid automobiles and self-driving cars.
