Yes, probably a short, and I think you should look at the ignition switch as the first suspect. It has two switches inside - one to send battery power to the various components, and a separate one to ground out the magneto when the mower is turned off. Could be a short between the two parts of the switch. Test it if you have the tools, otherwise try replacing it. Good luck! If this is helpful, please take a moment to rate my solutions, thanks!

That model number des not show up as a good number on the http://www.searspartsdirect.com site. Are you sure you have the belts on correctly? If it has 2 belts on the deck & 1 is not installed correctly they work against each other. Safely make sure that each blade will turn by hand. did you take the blades off? If they are too long by just a fraction, they will hit ach other, but that usually makes quiet a noise. Get your book out & systematically go over everything you touched or changed. It sounds like something really simple you have overlooked. you can go to http://www.searspartsdirect.com & enter a good model number & view all of the parts diagrams. Sometimes they are a big help, & at other times they just confuse you more:). Let me know what you find!!
