Bosch HBL645AUC single wall oven need wiring diagram

[darren412]

Looking for the wiring diagram on this bosch oven HBL645AUC  single wall oven.  Could not find the schematic supplied with this oven anywhere. Looked on this site and only found 2 issues with this model number that had nothing to do with my situation. There was one file I clicked on but the file showed up as could not be found ?? First I am not positive if this is normal operation to begin with this oven when its in the normal and not convection broiling cycle  but the complaint was that the broiling element to the customer had looked like a 1/3 of the element was not working ??   This is a broiling element with 3 seperate elements that it has for broiling in this oven. When I set the broil on the high temperature setting which is around 475 to 500 degrees you dont see the middle element glowing slightly red ??  Just the inner and outer elements glow slightly red and get super hot.. The middle element does get hot and cannot be touched during the beginning of the broil process so i think its getting 120 V but it definately is not getting 240 volts a that middle element when high broil is selected. just the inner and outer elements get 240Volts on high broil .  My meter shows zero volts at the terminals while its still connected to the middle element.  with out a wiring diagram there are a ton of wires going  through this model and chasing wires has gotten time consuming. Again I am not sure if this is normal operation for this broiling cycle on this model  and if its not I would appreciate a wiring diagram if someone has access to one.   I tried the search on this site for one but only came up with 2 situations involving this model number and neither issue pertained to mine.
