really? you've never heard the term 'hot wire' before?
hot wireing is a slang reference.. mostly going back probbaly to car theft. it involved of using a wire from the battery 'hot' terminal' directly to the ignition, thus powering the ignition. ( in a car setup.. one would then find the wire to the starter solenoid coil and arc it against the hot wire to make the starter spin.. on simple old ignition setups and on columns with no locks.. all you need is power to the coil and a spinning starter. )
hot wireing the coil is a good test as while your meter with 50k ohms of input impedance see's 12v on the coil... it may bee too poor a connection thru a switch or wire connection to pass enough current to run the ignition.
thus you run a 'hot wire' from the battery to the coil, thus bypassing any other wire connections and igniton switch in the line... like my previous message specifically stated...
