I solved the riddle it’s part number 53, when I removed the lower unit it must have come down and stuck to the lower unit and I picked it up and moved it to the box...I feel ignorant, simple but just didn’t see it in the schematic,even after studying it prob 30 times... thank you for all your help, sorry for being a nuisance on the issue, you’ve helped me diagnose and solve this dilemma... your time was greatly appreciated, thanks for putting up with my pain in the ass!!
