So very odd.? The connector is a 15 pin D with guide pins and cannot go in wrong.? Infinite between supplies and common, and between supplies and each other.
It appears that simply connecting the various rail returns together, as they are done at the backplane, causes the problem.? I will see which particular one is the issue.

Connector miskeyed?? Off by one?? bad?
Any idea what line is shorted?? Resistance with the power supply off but plugged into the backplane?
Guesses.

I have an 8711B where the power supply runs when out of the chassis but when plugged in it keeps trying to start as if there is a short.
I have determined that the supply acts this way when the small backplane is plugged in without any assemblies connected.
There are no shorts on the backplane and it is in perfect condition including connectors.
I just ordered the CLIP from ArtekMedia to help me look into this.
Has anyone ever seen something like this?? It's a new one to me!
