there are no diagrams or schmatics of the OBC that i,m aware of........as i said i have torn a few apart and for the life of me i can,t understand how they can advertise a rebuilt one...............there are reasons they have difference in part#,s lets say you have a 1996 powerdrive and a 1996 with powerdrive plus these carts are identical in every way.........2 different OBC,S and one won,t work on the other but yhou can use either battery charger on either cart and it will work.......i quit trying to figure them out a long time ago............................................... ....
