I need access to either a bump n jump manual or the power board schematic

crazykong isn't working for me.

I have a thread in the help section already.
I need to remember how to reconnect the wiring (though I think I have that) and I need to find some test points on the power supply board to make sure my voltages are right.
 
thanks mike, I got that from crazykong.com it's not clear enough for me.
I uploaded a couple of pics in my thread in the help section.

I think I really just need to know where to test voltages at from the power board that I just rebuilt.

j2 is what I need.


I think it's obv ious, which would put the black wire at the top of j2 while facing it in the cab. but I am not certain
