Disconnect the coil from the truck entirely, connect one jumper lead from the positive side of the coil to the positive post on the battery, and connect another one to the negative side but keep the other end from touching anything.
Connect a wire to the high tension post on the coil, and put a spark plug on the other end. Lay the spark plug on something grounded.
Take the test lead that is connected to the negative post and tap it on the negative battery post. Do not hold it for more than a second on the battery. The spark plug should give a nice bright blue spark with a decently loud snap every time you lift the wire off the battery. If it does not, the coil is bad.
