What's Causing Electrical Short?I have an "Intermatic" spring wound interval switch, P/N FD60MWC. Normally it's used to replace a wall on/off switch, but I thought I could wire it to an extension cord so we could automatically turn our radio off at night. Not so.........when I plug the extension cord into the wall outlet it shorts out (sparks at the outlet). What am I doing wrong? I cut one wire of the extension cord and connected the 2 cut ends to the 2 terminals on the timer switch. The radio isn't plugged into the female part of the extension cord when this happens.June 06 2009 - New Bern00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
