IF YOUR CABLE IS OK IT IS POSSIBLE THAT THE SWITCH IS SHORTING OUT

PAUL, September 2008

you've got a short to earth.usually i find that the flex has dammage and to save time and effort testing i just replace the flex.while doing this i also find the other common fault whitch is flex grips inside have pulled loose letting the connections becomeunsecured.caused by dopes pulling the tool towards them via the cord.
