RE: I think one of my backplates is wired wrong....

You really ask hard questions with minimal information. Here I would say at first glance that both transformers appear to be oriented the same way, with the primary leads toward the bottom of each photo. However, I have never seen an SL bass transformer with four red primary leads and one black. Moreover, there appears to be a lot insulation on the four red and and single black leads, suggesting they could be secondary leads, which carry high voltage. On the other hand, a secondary should have only have three leads, pos, neg, and ground. The transformer with the orange, yellow, etc, primary leads is like every other SL bass transformer that I have ever seen (N = 2), oriented with respect to the back plate as it should be. Take this question to SLOG or email William directly; he may know.
