.Another day I was fiddling around with the valve covers,putting new gaskets on it...and a wrench fell down on the passenger side of the engine,bounces off the exhaust manifold,then lands squarely across the positive battery cable and the purple "crank" wire on the solenoid,and it shorts,and the starter starts cranking away,the truck was in first gear and before I could jump out of the engine compartment,it runs over the top tray of my tool box,and ends up against a concrete wall a few feet away,the starter still humming away,trying to turn the tires!...

.................................................................................................I burned the crap out of my hands while attempting to get the battery cables off too,and destroyed a nice test lamp in the tool tray,that was now pancaked--and then I discovered an allen wrench had puntured my left front tire,that was in the tool tray....

:..that was a bad day...now I rarely look under a hood without taking off the battery cable!...
