what am I missing here. Can't find a defeat in any of the manuals. Secondaries don't have a ground defeat function for primary injection, I have what I thought was a ground defeat plug for the the secondary contacts with a jumper in but thats not working. I think it must just be the one for zone interlocking. I feel like I have figured this out before its just been years since i did primary on this one. Any help is much appreciated.

Ground Fault is defeated by shorting terminal B6-B7
Zone Interlock is defeated by shorting terminal B8-B9

I do not remember if it is easily seen which terminal is which, but can be difficult determining which secondary terminal is A and which is B and whether it is read from inside or outside.
