Jenn-air manual (by 2 users)

i have a jenn-air, SVE47600B, when you put power to the unit, the broiler element comes on and stays on. In the past, someone pried the door open, during a clean cycle. Than the unit would shut off in the middle of baking or broiling, so they called a service guy who took the wiring diagram when he left, he also unwired the door latch used during cleaning cycles. He told customer it needed a new control panel, the guy did not do the repair, he just unplugged the broiling element and used the stove top. So now i reattacted the door latch switch and hooked up the broiler element , then turned on power to the stove and sure enough the broiler came on and stayed on. with no wiring diagram and rusty skills i am looking for advice and help and maybe a wiring diagram. Went to sears web site and they have a control panel or a relay board(down draft), relay board (bake/broil).....pricing between 200-300$ each and i dont want to just throw money at it......HELP
