I've got a QDI DCRU board that was removed from a Weaver E8. I'd like to re-install it, however, as at the time of removal I hadn't planned on re-using it, I wasn't bright enough to note what wires were attached where.
I've basically got the hot and common AC wires coming from each truck, and the 2 wires coming from each DC motor. There's also a reversing lockout switch, but I know where that connects. Anyone have any idea where they're supposed to go?

Do an OGR Search on "QSI DCRU". Many threads about hookup methods.
Above from your photo. My guess is you're interested in AC & ACG for truck roller & wheel, and M1 & M2 for motor wires.
Here's a hijacked photo from recent For Sale thread showing what appears to be 4 wires blue, brown, orange, yellow going in from the top side.
Thanks, I didn't even notice those markings last time I looked at it, even with my glasses. Tracing things out, the - post of the bridge rectifier seems to go to the "R", but I suppose that doesn't matter, as the motors would need to be hooked to outputs of the board which are reversible. The AC and ACG are simple enough, but M1 and M2 are perplexing. If I recall, each motor's wirers were soldered directly to the board, rather than having 2 connected together (unless where they connected to the board simply acts to connect them), so I'm not sure if they were wired in series or parallel. If the latter, then each motor would need 2 places it connected to the board (4 wires), not just M1 and M2 (unless there are 2 solder points each for M1 and M2). I'll have to investigate further. Wish it were possible in the 2nd pic to see exactly where those wires connected (checked the thread, it isn't).
