I have a yard machine by MTD model 608 made in 2002. My wife tried to surprise me by cutting the grass. She almost had it done and the mower just quit on her, she tried to restart to no avail. I noticed the the fuse connected to the key ignition switch was blown. I replaced that and it started up fine, I cut the grass for 15 minutes and the mower quit on me again. Pulled out the fuse and sure enough it was blown again. I replaced it and now when I tried to start it it just blows the fuse, it won't even attempt to turn over. The fuse blows AS SOON AS YOU TURN THE KEY. I also checked the other fuse by the battery it is fine. I am not sure where to go from here, one friend of mine thought that it could be the electric clutch. I am fairly technically inclined, and my friend has fixed his mowers several times for many years. We are not sure the best way to evaluate what is causing this problem. I was also trying to find a wiring diagram so i could make sure all the wiring was in order, but i could only find them on MTD sites for purchase. I don't want to order that if i don't need too. Any ideas on the best way to evaluate the issue? Thanks!!
